This is a polyurethane dock bumper designed to protect trailer doors and dock edges from impact damage. It typically mounts on the rear of dry van or reefer trailers, absorbing shock when backing into a loading dock or during coupling. Replace the bumper when it becomes cracked, deformed, or worn to prevent metal‑to‑metal contact. The 3‑inch wide bumper fits many popular trailer models with a 3‑1/2 inch bolt hole spread and uses 1/2‑inch mounting bolts.
Verify bolt hole spacing (3-1/2" center-to-center) and overall dimensions (5-3/4" L x 3-3/4" H x 3" W) to ensure correct fit.
