Step 1: Materials
Parts Supplied:
2 – Cable PassThru Units | 12 – 2” Bugle Head Drywall Screws
1 – Rubber Seal in Cardboard Tube

Tools Required |
Drill |
#2 Phillips Bit |
Tape Measure |
Keyhole Saw |
Pencil |
Sharp Knife |
Stud Finder |
Step 2: Placement
Using your studfinder, determine a spot on your wall between studs to install your Cable PassThru. Ensure that the placement is clear of any wires, ducting, or plumbing, as we need a clear path through the wall.
Step 3: Prep for Cut
Once placement is determined, hold the Cable PassThru up to the wall. Level the unit using a Torpedo Level (Fig. 1). While continuing to hold it in place, use a pencil to trace the outline of the inner sleeve (Fig 2).
*Use included Wall Cutout Template to verify and adjust size as needed for correct fit.

Step 4: Cut CablePassThru Hole
Use a keyhole saw to cut out the hole traced in Steps 2 and 3. Cut out any insulation that may be in the wall where the hole is. Then use a long drill bit or similar tool to indicate the corners of the hole on the other side of the wall. Use the keyhole saw to cut the second hole on the other side of the wall.
Step 5: Install CablePassThru
Place one of the Cable Pass assemblies into the hole we cut in Step Two. Check once again to be sure it’s level. Place the six 2” bugle head drywall screws into the provided screw holes. Then use your driver to gently drive each screw into the drywall, making sure not to overdrive them. Repeat the process for the other side. You are now ready to install your rubber seal.

Step 6: Measure Gap
Once both Cable PassThru units are installed on either side of the wall, measure the gap between the edges of the PassThru tunnel (See Fig. 4). The completed seal will settle into notched lips.
Step 7: Measure the Seal
Push one end of the Rubber Seal through cardboard tube until it is protruding (Fig 5). Measure the exposed end of the rubber seal until it matches the length measured in Step 5 (Fig. 6). Continue to measure the rubber seal while rotating the tube to ensure it is even and protruding end is flush and square.
Step 8: Cut Seal
Using the cardboard tube as a measuring guide, cut the rubber seal to length with a sharp, serrated knife (Fig. 7).

Step 9: Insert Seal
With one CablePassThru door open, insert the folded rubber seal through the cable slot (Fig. 8). Unfold rubber seal in the PassThru tunnel, using hands to press it into the notched lips (Fig. 9).
Step 10: Finish
Seal with a tight bead of silicone caulk around all four exterior edges where the passthru abuts the wall. Congratulations, you’re done!
OPTIONAL:
For a more permanent seal: Smear a light coating of fast drying adhesive to the notched edges of the cable passthru units. Install and flatten the seal. As shown in Fig. 4
