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.
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
TwinWall or TripleWall along vertical
edges (Fig. 2).
Builder's notes: Drill Caps every 12"
for screws. Design framework 24-1/2"
O.C., or plan to rip TwinWall to 23-3/4"
wide. Cut capping with hacksaw.
