MXSAG Aluminum Truck Bed Cap Mounting Clamps — 4‑Piece Silver, Heavy‑Duty No‑Drill with Zinc Hardware

MXSAG’s 4-piece heavy-duty aluminum clamps secure a truck bed cap, topper or tonneau cover quickly without drilling. These universal clamps are built for fast, no-drill attachment of camper shells, tonneau covers and toppers to pickup beds. Constructed from high-grade aluminum with zinc-plated bolts and washers, the set combines corrosion resistance with strong gripping teeth to hold accessories firmly in place across most makes and models.

How do these clamps attach without drilling?

The clamps use a bolt-and-jaw system that tightens against the truck bed flange, creating a firm hold without penetrating the bed. You simply position the clamp, run the bolt through the clamp body and tighten with a wrench or ratchet until snug.
