Hook Truck Restraints — Secure Trailer Engagement for Every Dock
Hook-style truck restraints engage directly with the trailer’s rear impact guard, providing a positive mechanical connection that prevents trailer walk during loading and unloading. Wilcox installs hook truck restraint systems for facilities that need reliable restraint at every dock position without the complexity of hydraulic systems.
Mechanical. Reliable. Compliant.
Hook restraints are a cost-effective alternative to hydraulic systems for facilities with lower cycle counts or budget constraints. Wilcox helps you determine the right restraint type for each dock position and installs to manufacturer spec with full safety testing. All documentation provided for your safety compliance records.

Frequently Asked Questions
A truck restraint locks the trailer to the dock to prevent trailer creep or early departure during loading. Without one, trailers can shift — a leading cause of dock accidents. Ontario workplace safety regulations and OSHA increasingly require active restraint systems.
Hydraulic restraints engage automatically and integrate with dock light systems to control forklift access. Hook restraints are manual — reliable and cost-effective for lower-volume docks. Wilcox recommends hydraulic for high-cycle operations.
Most ICC-compliant trailers work with standard hook and hydraulic restraints. Specialty trailers (flatbeds, tankers, low-boys) may require alternate restraint configurations. Tell us your trailer mix during consultation.
Annual service: mechanism function test, hydraulic check (if applicable), safety light test, and mounting hardware inspection. In harsh environments (salt exposure, freeze-thaw), inspect more frequently.
Wilcox stocks common restraint parts on service vehicles for same-day repairs. Our emergency line is 1-800-528-4131 — 24/7 response for any dock safety equipment failure.
