SECTION 7" Wall Attachment Channel Installation

7-1. Measuring and Cutting Wall Attachment Channel

The last attachment channels to be secured are the wall channels to allow you to secure the patio sidewalls to the house. Each room wall module will rest on the lip found on the inside of the bottom track. This lip must be taken into consideration when measuring for the wall channel cut lengths.

7-2. Slitting or Notching the Wall Channel
Slitting the exterior edge of the wall channel will allow it to fit into the bottom track more easily. Using the miter saw, cut a 1-1/2 inch slit next to the outside fin of the attachment channel on the bottom.

Note: For the Weather Guard roof, cut a 1-1/2 inch slit on the top as well (Figure 7.2 Detail "A"). Repeat this for the other wall channel.

Note: For the beam roof, cut a notch so that the outside face of the wall channel covers the outside edge of the roof attachment channel. See Figure 7.1, Detail "B", and Figure 7.2, Detail "B" for a profile view of the notch. Repeat this for the other wall channel.

Note: In applications under an existing roof or in between two posts (where the module spacing will be very tight) it may be necessary to cut off the outside fin of the wall channel in order to fit the module(s) into place. The fin will be reattached once the module is in place.

7-3. Checking for Square
Place the wall channel inside the bottom track at the house wall and square it with a level. Place a mark on the house wall at the outside of the wall channel. Do the same for the other sidewall attachment. Measured from mark to mark, the dimension should be the same as the front wall width (Figure 7.3).

7-4 Pre-Drilling, Sealing, and Securing the Wall Channel
Molly bolts will be used to attach the wall channel to the house. Starting at the uppermost end of the wall channel, mark your first location for attachment. Continue to mark fastener locations every 16 inches. Remove the channel and predrill 1/4" holes into the wall channel at each mark. Before bolting, deal the wall channel by placing a bead of sealant in the sealant reservoir on the back en of the extrusion (Figure 7.4). Depending on the material that is on the house wall, use polyurethane or silicone.

Note: Expanding inserts may be used to secure the bolts to a stucco wall.
