1500A Polycarbonate Capping, 8mm Joiner Cap 4 ft

Qty.

$9.60

Simplify Assembly

Adding TwinWall or TripleWall to your wood framework is easier when using these special pieces to hold the panels in place. The Caps are made of a tough, sunlight resistant polycarbonate, and are weatherproof and maintenance-free. 2-7/8" across (longest side).

Use End Caps on the top and bottom of TwinWall or TripleWall to close the channels. This keeps out dirt and insects. Also use End Caps on the outside edge of corner panels (Fig. 1).

The Joiner Cap is used to connect 8 mm TwinWall over studs and rafters (Fig. 2).

Use Gasket Washers on Washer Head Screws where fastening the center of panels to support blocking.

Builder's Notes: Drill Caps (Base) every 12" for screws. Caps are easily cut to length with a hacksaw.
