Overcenter straps are constructed with a simple overcenter buckle rather than a ratchet or cam buckle — a great solution for quick cinch applications. Wind the adjustable strap into the buckle, then clasp the lever closed, and the strap locks down firmly for a secure hold. Proper use and correct winding are the key to a secure load, and these straps make it easy to get right: frequently used to hold down tarping on the sides of trailers, they keep tarps, covers, and side curtains snug and secure mile after mile.
