The Kelley HH3000 HIDDEN HOOK restraint has a unique, non-impact, recessed design that is ideal for new construction or remodeling applications. The HH3000 vehicle restraint system is mounted in a pit under the leveler and, when retracted, offers a clean dock face, allowing unobstructed access to smaller delivery vehicles, trailers with hydraulic lift gates and an open drive for unimpeded snow plowing or drive cleanup. The hydraulically activated HH3000 effectively controls vehicle movement by grabbing and holding the rear impact guard throughout the loading/unloading process. It also includes advanced safe engagement signaling and an interlock-capable control panel.
