A 45 degree bend in the arms of our aluminum dump truck tarp system can ensure against costly damage and lost time routing the tarp arms out of the way of bucket loaders, reducing the likelihood of an accidental collision with the arms. They are easy to splice in, so you can add them later if you think you might need them. Comes with (2) 45 degree elbows, (8) 5/16" x 1-3/4" Bolts, (8) 5/16" Nylock nuts, and (8) 3/8" Washers.
