other side as shown below. The back side of the screen material should be placed upwards.
Step 7: Insert the rods (r) through the sleeves according to their corresponding lengths on each edge of the screen
as shown below. The short rods (top/bottom) will overlap to secure a firm grasp in the middle areas.
Step 8: Carefully and gently place the assembled frame on top of the screen material in the marked areas as shown
below. Make sure to not allow the angle edge of the frame to come in direct contact with the screen material to
avoid puncturing it.

Center Support Bar
Step 9: Insert the Center Support Bar (o)into the upper top groove on the back of the frame with the bottom end
near the approximate center point of the frame and rotate it in at an angle so that both ends of the bar are in
alignment with the groove.
Diagonal Sizes of 150” and below use 1 x Center Support Bar
Attention: Do not proceed with the Edge Trim installation until making sure there are no ripples in the material.
Step 10: Hook one end of the spring and secure inside the groove of the frame, use the spring hook (i) to attach the
spring to the grommet hole located on the screen material’s outer edge in the following order.
Begin by first attaching the center points on both vertical (left/right) sides, steps 1-2. Then the center points on both
horizontal (top/bottom) sides, steps 3-4. Once all center points have been secured, make sure the screen material is
still within the marked areas before proceeding to attach the next springs.

Continue attaching the rest of the springs to the material in the following order in steps 5-12.
Note (after all springs have been attached):
Correct material installation –Corners of the screen material are properly wrapped around the corner edges of the
frame and material is evenly tensioned and flat, creating a nicely taut surface.
Incorrect material installation –The corners of the screen material are not properly wrapped along the edge of the
frame leaving the material with unbalanced tension and an uneven finish. To correct, detach springs from material at
the corner(s) where material does not lie flat along the edge of the frame, reposition the material so that it lies flat
and wraps along the edge of the frame, and reattach springs to the material.
Note: Please make note of the yellow label and spring in the center of the frame. This is an indicator to start the
screen material installation process from the middle area of the frame.
How to avoid getting ripples on the screen’s material surface
Solution: Pull and smooth out the material using your hand from the center to the corners, creating a nicely taut
surface as shown below.
Edge Trim Installation
Step 11: Place the edge trim frame
pieces over each end of the frame.
To avoid ripples forming in the material it is imperative that all of the corners are properly wrapped around the
edges as illustrated in the check mark diagrams.

as shown in Step 1. Repeat for other side.
Once both top and bottom edge trim frames have been connected, attach the vertical (left/right) sides edge trim
frames (d) using the Elbow Joints M4(c) and secure with four M4x4 screws (m) on all corners, Step 2.
Step 12: Install the angle cover (n) on each corner of the frame as show in the illustration below.
Step 13: Install the springs (q) in each middle area to secure the bezel trim edge frame.
Wall Installation
Step 14: Measure the overall length and height of the frame and drill holes for the top brackets. Line up the wall
brackets with the drilled holes on the installation location and screw them in using a Phillips screwdriver. If not
installing into a structural wood stud, use a hollow wall anchor then screw in the M5x50 wood screws with a
screwdriver. Make sure the brackets are leveled.
