Aluminum cross tube fits through the pocket on the end of your tarp, attaches to 90 degree elbows that either fit in, or are welded to, your system's upper arms, and pulls your tarp to the back of your truck or trailer. Slightly elliptical tube measures 2 1/8" x 2 1/8" x 95", with a 7/8" hole drilled 3/4" from both ends on both sides. This cross tube does not fit Aero systems.
This cross bar will fit most systems on trucks up to 96" wide. If you have a wider truck, you can order a 103" cross tube (oversize shipping charges will apply).
This aluminum tube can also be used as an upper side arm.
