The M3 Cam Lock Kit is a robust, field-proven hardware system designed to secure roll-up doors on trucks, trailers, and cargo vans. Built around Whiting’s industry-standard cam lock mechanism, this complete kit ensures that your rear door closes tightly, stays locked during transport, and withstands repeated daily use in demanding conditions.

Engineered with precision-cast components and reinforced steel parts, the kit provides reliable operation under frequent vibration, weather exposure, and heavy loading environments. It is especially suited for logistics fleets, delivery vehicles, freight trailers, and service trucks that require long-lasting hardware with minimal maintenance.

The rotating cam latch offers smooth locking action, pulling the door panels in firmly and resisting prying or tampering. When used with the included hinges and mounting brackets, the system provides a tight, stable, and aligned door seal to help protect cargo from theft, dust, and moisture ingress.

Installation is straightforward and compatible with most Whiting-style or universal-style roll-up doors. Whether you're building new truck bodies or replacing damaged components, this kit is a trusted solution for fleet managers, body builders, and repair professionals alike.
