Wire cutter, crimper and stripper 15. Utility knife 16. Electrical tape The truck or trailer on which installation is being done must be parked on a level surface. This prevents box from twisting, which can cause a poor installation. Box must be square and straight, center must not be pulled together or spread apart. Make adjustments prior to installation. Inspect box for sharp edges or points that make contact with tarp and/or cables, remove or grind smooth. It may be necessary to remove or reposition ladders or other devices that manufacturer. If you have an extension on top of your box, make sure it is secure by bolting in place. Most fasteners used in this installation are 3/8 x 1 self threading bolts. A 5/16 hole must be drilled to obtain correct tap drill hole size. Attach these bolts only to secure structures on box. In some cases it will be necessary to use washer and nuts or other types of fasteners (NOT FURNISHED) to ensure a solid anchor. Before you begin, measure the outer length and width of your box. Also measure the length of the tarp and the width of the end caps to ensure you have received the correct size. The tarp must measure between 8 and 16 shorter than the box length. The end caps must be at least 1 narrower than box width, usually 1 to 3 narrower. NOTE: Some systems may require end cap variations which will result in short outer tarp lengths. 5
