The lockable clamp arm system allows users to load, secure, and unload ladders in seconds, no straps or tie-downs required. The arm rotates below the crossbar for a clear loading path and automatically clamps the ladder firmly in place, providing a quick, one-person operation that boosts safety and efficiency on the job site.

Designed to fit a wide range of commercial vans, including Ford Transit, Ram ProMaster, Mercedes-Benz Metris, and Chevy Express, Holman Clamp & Lock Racks utilize factory roof mounting points for no-drill installation. Adjustable grips accommodate extension and step ladders of various sizes, while dual- or single-side configurations let users customize their setup for maximum productivity.
