Original Dok-Lok® Rotating Hook Restraints

The #1 name in vehicle restraints, Rite-Hite is the expert when it comes to Dok-Lok® rotating hook restraints. We created the vehicle restraint industry with the introduction of the first-ever rotating hook restraint on April 22, 1980. Innovated to meet today’s standards, but fundamentally the same for over 40 years, rotating hooks set the industry standard with the most advanced RIG technology. Offering the greatest reach, creating a two-point entrapment for ICC bars and today’s RIGs, rotating hooks help reduce trailer separation accidents, such as: early departure, trailer creep, landing gear collapse and more. When optimized with Shadow Hook technology, rotating hooks can properly secure intermodal chassis as well as obstructed RIGs.
