3 Attaching
It is important that the rear roof channels be securely anchored to a sound and flat mounting
surface. A special mounting board (2x4,2x6)x19' 10" (38 mm x 89 mm, 38 mm x 140 mm) x 604,5 cm can be
used if existing surface is questionable or on mobile homes. The mounting board should be attached with wood
screws drilled into the wall studs on frame construction. Masonary anchors should be used on brick or masonary
installations. Also on frame construction, if stud or rafter spacing is greater than 16" (40,6 cm) on center, use the
mounting board. Countersink all fasteners.
Option 1 Attachment to Stud or Rafter
rear roof channel level on wall, drill a 3/16" (5 mm) hole, 1" (2,5 cm) from top flange, through rear roof channel's
web and wall at every stud or rafter. Make sure there is a hole on each end of channel. Remove rear roof channel
from wall and enlarge holes in rear roof channel with a 7/16" drill bit. This hole will enable the fastener to pass
through the rear roof channel. Align holes in wall with holes in rear roof channel. Attach rear roof channel to wall
with 3/8"x2 1/2" (10 mm x 6,4 cm) screws and washers, provided your local code permits the use of this screw.
Note: If a special mounting board was used, holes are provided in rear roof channel for attaching to wall.
Option 2 Attachment to Brick or Masonary
locally) 12" (30,5 cm) on center. Level rear roof channel on wall, using holes in rear roof channel as a guide,
drill holes in wall at the center and each end of channel with proper size masonary bit ( do not drill holes in mortar
joints). Attach rear roof channel to wall with masonary anchors. Repeat procedure for remaining holes in rear
roof channel. Note: If a special mounting board was used, holes are provided in rear roof channel for attaching
to wall.
