Polacoat Da-Plex
Semi-Rigid Screen

Preparation
It requires at least four people to assemble a Da-Plex Semi-Rigid. To maintain optimal image geometry and screen alignment, a lat and
straight wall free from obstructions and angular distortions should be used. A wall opening with 5” + the ordered viewing height and
5” + the ordered viewing width must be used to maintain the precise in-wall it of the Da-Plex Semi-Rigid. When assembling the
screen, choose a clean work area using padded material or other soft, clean materials. The work area larger than the overall screen size
and directly in front of or behind the wall opening where the screen is to be installed.
NOTE: Please read through the installation steps and note wait times. The rolled screen surface needs to be acclimated to the room for
48 hours prior to installation (Step 1). Once the surface is unrolled it will need to lay in its unrolled state for 4 hours (Step 2).
Screen Orientation
Polacoat® In-Wall rigid rear projection screens have a polished surface and a matte, coated surface. The polished surface should always
be installed so that it faces the projector and the matte surface must face the audience. If screen has anti-glare coating, the anti-glare
surface should always face the projector.

Maintenance and Protection
Projection screens should always be installed after the completion of construction, drywall, and painting of all adjacent areas. If
construction work needs to occur near an installed screen, clean polyethylene sheeting should be used to cover and protect both
surfaces. Never apply adhesive tapes to the coated surface. Always be careful to guard the screen against damage from moving
scafolding, ladders, or staging materials.
General Cleaning
Never use solvents on or near Da-Lite rear projection screens. Remove dust by gently blotting the screen with a soft, clean, lint-free
cloth.
Dry Soil Marks
Clean with VM&P Naptha or with Da-Lite Lenskleen and a soft, clean, lint-free cloth.
Cleaning of Frame and Trim
The exposed surfaces of the aluminum frames can be cleaned with a dilute solution of detergent and water, followed by a clear water
rinse. Use a soft, grit-free cloth to preserve the anodized inish. Protect screen surface during frame cleaning. Do not use abrasive
cleaners or solvents.

Installation
1. Prepare clean working area and use padded materials or soft,
clean materials in the space where the screen will be
assembled on the loor.
WARNING: The screen surface should be allowed to
acclimate to the temperature and humidity of the location
where it will be installed. Da-Lite does not recommend
beginning installation if there is high humidity in the
room. Care should be taken to prevent water from
condensing on the screen surface as it may leave
permanent marks on the screen surface.
NOTE: Da-Lite recommends that the roll with screen surface
and hardware be removed from the crate and acclimated to
the location at least 48 hours prior to installation.
NOTE: Wear the provided gloves any time the screen surface
is being handled and also during lifting to provide grip.`
2. Carefully unpack unit from crate and packaging. Using four
people, unroll the screen. Locate one person on each end of
the roll with the other two people used as support for the
middle of the roll. Before unrolling the screen, ensure that the
edge/end of the surface is nearest to the loor. While
maintaining slight pressure on the roll, cut each piece of tape
wrapped around the roll at the edge/end of the surface. Once
all tape pieces have been cut, the screen surface can be
unrolled. This should be done gently and in at a measured
pace to prevent damage to the surface. There will be elastic
potential energy stored in the roll. Carefully guide the screen
surface when unrolling, particularly on the last wrap to
prevent the surface from springing out or scraping itself. The
audience side of the screen surface will be face down after it
has been unrolled.
WARNING: Do not step on the screen surface or place
objects on the screen surface during this step or during
installation. This may cause irreparable damage to the
projection coating.
NOTE: Da-Lite recommends that the screen surface remain in
this lat, unrolled state for at least 4 hours prior to Step 9. This
will allow the screen surface to fully adjust to room
temperature and will signiicantly reduce the risk of breakage
or damage. Do not proceed to assembling the frame on the
screen surface if these precautions have not been taken.

Installation (continued)
3. While the screen is resting, the T-tracks can be installed into
the wall opening. Measure 2½” from the side of your wall
opening to locate the end of the irst T-track piece
(See Figure 1). Using one of the 4” pieces of trim, snap the
trim into place on one end of the T-track, place the T-track in
the opening and slide until the lower portion of the trim is
against the wall. Secure that end of the track with a #10 screw
in the hole closest to the end (See Figure 2).
NOTE: Most screen units will have one piece of T-track for the
side openings and two pieces each for the top and bottom
wall openings. Larger sized units (above 14’ wide) may have
three pieces of T-track each for the top and bottom openings.
4. Using the other 4” piece of trim as a guide, secure the
opposite end of the T-track section on the end hole with a #10
screw. Once both ends are attached, slide the 4” trim pieces
along the track to align the other positions and attach a #10
screw into the hole openings until completed (See Figure 2).
NOTE: Sliding the trim along the T-track will maintain the
proper alignment when attaching the T-track to the wall. This
alignment is necessary to allow the trim to snap on easily at
the end of the screen installation. Ensure the opening is level
on all four sides. If the opening is not level, the T-track will
need to be shimmed in order to ensure the screen trim is
level once attached to the T-track.
5. Repeat Steps 3 and 4 until all T-track sections have been
secured to the wall opening (See Figure 3). For top and
bottom sections, use 4” piece of trim to overlap at the seams
as a guide to ensure that both T-track pieces are lush with
each other in the wall opening.

6. Mount the irst lifting bracket in the top section of the wall
opening behind the T-track. Measure 2⅛” from the back
(projector side) of the T-track to the back edge of the lifting
bracket and ½” from the edge of the opening to position the
bracket correctly. Use 1/4” x 1” lag screws to attach the bracket
(See Figure 4).
NOTE: When installed in the correct orientation, the bottom
lip of the lifting bracket will be the side closest to the T-track.
7. Repeat Step 6 for the second lifting bracket at the top section
of the screen in the opposite corner (See Figure 4).
8. Position the third lifting bracket 2⅛” from the back of the
T-track in the center of the top section of the wall opening
and mount with 1/4”X 1” lag screws (See Figure 4).
NOTE: After completing this step, there should be three lifting
brackets mounted into the top section of the wall opening
behind the T-track. Check that these brackets are secure.
They will be used to guide the screen surface into place and
support its weight until the T-track and screen frame are
attached to each other.
WARNING: After completing this step, do not proceed
further in the instructions until the screen surface has
remained in a lat, unrolled state for at least 4 hours.

9. At the unrolled screen surface, peel back the protective paper
approximately 3/4” on all sides. This will allow the frame to be
attached easily to the screen surface.
NOTE: Do not remove the protective paper completely. This
will be done at the end of the screen installation in order to
protect the surface during the hanging process.
10. Center the irst rubber gasket on the screen surface edge and
press it into place starting at one end. Repeat this step for the
three remaining sides of the screen.
Installation (continued)
11. Place the frame sections around the screen surface. Attach to
frame over the rubber gasket with set screws facing upwards.
Use a rubber mallet to gently tap the screen frame into place
if needed (See Figure 5)
12. Starting from the center on each side, tighten all set screws
on all four sides of the frame using the 1/8” hex key.
Approximately two threads should be visible on each set
screw when properly tightened.
13. Place the hoisting bracket in the center of the top and bottom
sections of the screen frame. Attach to frame using the
provided cap screws and a 3/16” hex key.

14. Feed the irst rope through the large hole on the left hoisting
bracket so that the knotted end makes contact with the
inside of the bracket. Then, feed the rope through the left
lifting bracket that was installed into the wall opening behind
the T-track (See Figure 6).
15. Repeat Step 14 for the second rope through the right and the
third rope through the center hoisting and lifting brackets
(See Figure 6).
NOTE: At this point, all three ropes should be fed through the
hoisting and lifting brackets. There will be no rope placed
through the single hoisting bracket on the bottom of the
screen. On the rear (projector side) of the wall opening, a
person will be needed in the following steps to guide the
three ropes as the screen is being lifted.
WARNING: Do not lift the screen into place if the ropes
have not been fed through the hoisting and lifting
brackets.
Figure 6 Figure 7
16. Lift the screen assembly to a vertical position on the loor
parallel to the wall opening. On the projector side of the wall
opening, one person will be holding all three ropes without
slack and guiding the screen to an upright position. On the
audience side of the wall opening, to lift there should be one
person on the left side of the screen, one person on the right
and one person supporting the top center of the screen
frame at the center hoisting bracket. After this step is
completed the screen will be standing on the loor in front of
the wall opening (See Figure 7)
CAUTION: Do not allow the screen to twist or bow during
this step. Without careful lifting, there is potential to
crack, break or shatter the screen surface. Four people
must be used during this step.

Installation (continued)
17. Raise the screen assembly into the wall opening. On the
projector side, one person will remain holding all three ropes
without slack, guiding the screen into place. On the audience
side, two people will lift the screen vertically, one on the left
and one on the right side. These three people (one rope
control and two lifters) will coordinate together to lift the
screen into place. The fourth person should be on a ladder on
the projector side helping the rope control and lifters guide
the screen assembly into place until all three hoisting and
lifting brackets attach to each other at the top of the wall
opening (See Figure 8).
NOTE: During this step, be careful not to touch the projection
coating on the audience facing side of the screen assembly
along the screen edges.
NOTE: At the end of this step, the screen assembly’s weight
should be supported by the hoisting and lifting brackets and
it should be inside of the wall opening.

Installation (continued)
18. At the top section, align the T-track and the frame. Insert eight
tensioning assemblies (four per frame section for larger
screens). Align the tensioning assemblies so that they are
evenly spaced across the length of T-track and frame (See
Figure 9)
19. Tighten a minimum of two tensioning assemblies per frame
section between the T-track and frame using a 1/2” wrench.
After two or three turns on one tensioning assembly, move to
another in order to prevent the bolts and nuts from binding.
Keep using this alternating method until at least two (or
more) tensioning assemblies, per frame section, have secured
the frame to the T-track on the top section of the screen
assembly. As the tensioning assemblies are tightened the
screen frame will pull gradually closer to the T-track until
there is no more adjustment.
CAUTION: Do not proceed to next steps until a minimum
of two tensioning assemblies per frame section are
attached fully and are holding the screen weight on the
top side.
20. Remove the three lifting brackets from the wall opening
behind the T-track by loosening and removing the 1/4” x 1” lag
screws. The three ropes should also be removed at this time.
NOTE: Once the lifting brackets have been removed, the
screen assembly will be held in place by the previously
attached tensioning assemblies.
21. Tighten the remaining tensioning assemblies on the top
section of the screen assembly until all eight (four per frame
section) are evenly spaced and secure on the top side.
NOTE: Use the alternating method of two to three turns on
one assembly then moving on to another assembly to
prevent the bolts and nuts from binding.
22. At the bottom section, align the T-track and the frame. Insert
eight tensioning assemblies (four per frame section for larger
screens). Align the tensioning assemblies so that they are
evenly spaced across the length of T-track and frame.
23. Begin tightening the tensioning assemblies between the
T-track and frame using a 1/2” wrench. After two or three turns
on one tensioning assembly, move to another in order to
prevent the bolts and nuts from binding. Keep using this
alternating method until the tensioning assemblies have
secured the frame to the T-track.
NOTE: These tensioning assemblies do not need to be
tightened down completely (no threads showing) because
the top frame is already anchoring the screen in place. The
bottom needs to be secure enough to the installer’s
discretion.
24. Repeat Steps 22 and 23 for the left and right sides of the
frame, using only four tensioning assemblies per frame
section.
25. Snap the trim into place on the T-track on all four sides of the
inished screen assembly.
26. Carefully remove the protective paper on the audience side
of the screen surface to complete the installation.
