This model is treated with DreamLine’s
exclusive ClearMaxTM Glass technology.
This is a specially formulated coating
that prevents the build up of soap and
water spots.
Install the surface with the ClearMaxTM
label towards the inside of the shower.
Please note that depending on the
model, the glass may be coated on
either one or both surfaces.
For best results, squeegee the glass after
each use and dry with a soft cloth.

Preparation
The safety of any installation is the responsibility of the installer.
Professional installation recommended.
To prevent serious injury, do not lean against the installed glass.
1. Prior to installation, examine all boxes and packages for shipping damage and compare the piece count
with your packing slip. After opening all boxes and packages read this introduction carefully. Check that all
of the needed parts are included in the package by checking off the components on the “Detailed
Diagram of Shower Door Components”. If the unit has been damaged, has a finishing defect, or has
missing parts, please contact our customer support department within 3 business days of the delivery
date. Please note that DreamLine®will not replace any damaged products or missing parts free of
charge after 3 business days or if the product has been installed. Contact DreamLine®if you have any
questions, and please provide an order number, job name or other proof of purchase to help us identify
your original order.
2. Please note that you should consult your local building codes with questions on installation
compliance standards. Building and plumbing codes may vary by location, and DreamLine®is not
responsible for code compliance standards for your project and will not accept any returns.
3. If this unit is going to be installed in a new construction, please install all of the required plumbing and
drainage before installing the shower. Use a competent and licensed (if required by local code) plumber
for all plumbing installation
4. Please make sure that prior to beginning the installation, the surfaces are leveled and solid and will be
able to support the total weight of the unit. Also make sure the walls are at right angles. Irregular
installation surface level, radius corners or improper angle of side walls will result in serious problems for
your installation. Please, note that some adjustments and drilling might be necessary during the
installation process.
5. Please protect all primary surfaces of the product during installation. Never set your glass down directly
onto a tile floor. Leave corner protectors in place until necessary to remove them. Always use a piece of
wood or cardboard to protect the bottom edge and corners of the glass prior to and during installation.
6. This unit must be installed upon a finished threshold and against finished walls.
7. The return panel for this model has up to 1/4“ of out-of-plumb adjustment within the u-channel.
Do not exceed this tolerance. The inline panel does not offer any adjustment.
8. This model requires that you drill into the threshold for proper installation.
9. This model requires a minimum 2-1/4” of flat threshold space for installation.
10. Installation of the Guide Rail brackets into a stud or 2 x 6 wood reinforcement is strongly
recommended.
11. Professional installation required.
NOTE: DO NOT attach the handle to the door glass until instructed to do so. DO NOT
use the handle to lift the glass during installation. This may result in damage to the
glass and/or serious injury. Always use an assistant and/or a professional grade glass
suction cup when handling heavy glass panels.

threshold required
1. Check both of the finished walls for plumb and the
threshold for level. Check your threshold against the
minimum threshold requirement of 2-1/4” for this unit.
Compare the overall (outside) dimensions of the
enclosure against the threshold to ensure that it will fit.
(Fig 1)
NOTE:
This model does not allow for out-of-plumb adjustment.
2. Measure the W2 dimension from the finished corner
of the opening over to the return panel threshold.
(based on the model size as shown on the “Shower
Enclosure Plan” Page 9)
Next, measure the W1 dimension of 34-3/4“ out from
the wall as the width of the return panel. These will be
the outside dimensions of the installed enclosure.
Use a carpenter’s square as a guide and extend this line
across the primary threshold to the opposite wall to use
for reference in Step #14 during the installation of the
U-channel for the inline panel glass. (Fig 2)
W1 = 34-3/4”
W2 = between 44-3/8” min > 48-3/8” max
OR
W2= between 56-3/8” min to 60-3/8” max
NOTE: This model requires a minimum 2-1/4”
of flat threshold space for installation.

4. Set the U-Channel (#01) aside and drill the holes in the wall using a Ø5/16” drill bit and insert
the Ø5/16“ Plastic Wall Anchors (#16) into the holes. Mount the U-channel (#01) to the wall using
the ST4.2×40 Countersunk Screws (#17). (Fig 4)
3. Align the outside edge of the U-Channel (#01) to the inside of the mark from the previous step on
the return panel side of the unit. Level the U-Channel (#01) vertically (plumb), mark the position of the
U-Channel (#01) on the wall, and mark the four holes for drilling through the pre-drilled holes in the
u-channel. The placement of this u-channel must create an opening that is within the model dimensions
of the door section, depending on the model size: <48” (SHEN-6434480) or <60” (SHEN-6434600 )
See the “Shower Enclosure Plan” on Page 9 for overall dimensions. (Fig 3)

into the U-channel (#01) and level it vertically (plumb). Make sure the Return Panel Glass (#22) is
aligned with the shower base or threshold. (Fig 6)
5. Attach the Stationary Glass Connector (#23) to the top of the Return Panel Glass (#22).
Attach the Bottom Bracket (#24) to the bottom of the Return Panel Glass (#22). Use the supplied

threshold.
Drill a hole in the shower base or threshold using:
◾ Ø1/8” drill bit for an acrylic base or
◾Ø5/16” drill bit for an anchor for a tile threshold.Mount the Bottom Bracket (#24) to the threshold
using the Truss Head Screw ST4.2×55 (#25). (Fig 9)
10. Apply a quality mildew-resistant silicone to the inside of the U-channel (#01).
Be sure to apply silicone to the screws and screw holes in the channel as well. (Fig 10)

This distance will represent the finished
opening size (L) that will be used to
calculate the finished cut dimension for the
Guide Rail (#04) in the next step. (Fig 12)
11. Place the Return Panel Glass (#22) back into the
U-channel (#01) and assemble the Bottom Bracket (#24)
to the Return Panel Glass (#22). (Fig 11)

Rail (#04) to fit the finished opening.
Measure the finished opening width at the position
of the Guide Rail (#04) for the model height:
The Guide Rail (#04) is 1“ less than the model size.
and will need to be cut to 1” less than the finished
opening size (L). (Fig 13)

14. Align the outside edge of the
U-Channel (#01) to the inside of the mark

the position of the U-Channel (#01) on the
wall, and mark the four holes for drilling.
