Wheel chocks keep a trailer from creeping away from the dock while it’s loaded. Use two per dock position, set snugly under the tires.
Choose solid molded rubber (7″ x 9″ x 7″) for stability and long life, or aluminum (7″ x 11″ x 8″) with a claw-like base that grips varied surfaces. A zinc-plated chain keeps each chock where it belongs.
