Can anyone tell me what the name of the strip of aluminum or fiberglass that people put across the back side of a tip up canopy. It covers the area that closed on the roll bar? Also, does anyone have instructions to make one? Unfortunately I was unaware that the tip up cannot be left partially open on startup and I snapped a piece off at the tip I will use "weld on 3 " to reinstall it but would like to have the strap on to insure that it stays there. Thanks.
