Magna-Loc Eave Plate and Magna-Loc panels must be installed prior to Vented Ridge installation (see pages 43-53).

1. Once panels have been installed, slide Back-Up Channel under upper edge of panels. Position Back-Up Channel to allow

for proper installation of vented ridge assembly. Use C-clamps to hold Back-Up Channel in place.

2. Apply a row of Double Bead Tape Sealant across panel, up and over all ribs approximately 0"-2" from panel end on

both sides of ridge.

3. Install Magna-Loc End Dams over Tape Sealant. Before continuing make sure End Dam placement will accommodate

Vented Ridge Cover.

4. Once closure is set in Tape Sealant, fasten through End Dam, Tape Sealant, Magna-Loc panel, and into Back-Up Channel

with (5) #12-14 x 1" SD N/W per panel. C-clamps may be removed once Closures have been fastened.

5. Once all End Dams have been installed, place a row of Double Bead Tape Sealant across top of End Dams on both sides of

ridge. Tube Sealant must be used to fill any and all gaps left around End Dams.
