PREPARATION
NOTES:
Prior to tarp system assembly, park truck or trailer on level ground.
Box must be square and straight, center must not be pulled together or spread apart.
Remove or grind smooth any sharp edges or points contacting tarp and/or cables.
Remove or reposition any interferences with tarp. If modications to box are needed,
consult box manufacturer.
Most fasteners used in this installation are a 3/8” x 1” self-threading bolt. A 5/16” hole
must be drilled to obtain correct tap drill hole size. It may be necessary to use washer
and nuts or other types of fasteners (NOT FURNISHED) to ensure a solid anchor.
Before beginning, measure outer length and width of your box. Also measure length
of tarp and width of the end caps to ensure you received the correct size. Tarp must
measure 8” to 16” shorter than box length. End caps must be 1/2” to 3” narrower than
box width.
Some applications may require end cap variations which result in shorter tarp lengths.
Ensure extension is secure by bolting in place on top of your box.
