We are open for normal business hours Monday to Friday from 7:30 AM to 4:30 PM. We are limiting the number of staff members in the office and practicing safe distancing precautions. We are encouraging all of the team members to wash their hands and use hand sanitizer whenever possible along with cleaning door handles, debt machines, handrails, photocopiers, and desks. We want everyone who walks into our office to feel safe. We still offer 24/7 Emergency Service. 


The Hold-Tite is a non-impact, self-aligning, hydraulic restraint that is exterior mounted to the front of the loading dock.


  • Actively seeks and secures a trailer's Rear Impact Guard (RIG)
  • Maintains a positive hydraulic hold of the RIG for zero running room
  • LED 3-light system for advanced communication between the truck driver and dock attendant
  • Push-button activation with custom PVC solid-state controls (115v single phase operation)
  • Zinc-Plated
  • iDock® Controls with Interactive Message Display
  • Override passcode
  • Automatic light sequence
  • Auto restore and activation of the amber caution light
  • Low profile, non-impact design (wall or driveway mount)
  • A light indicator if unable to secure a trailer’s RIG
  • Positive hydraulic restraining force to minimize “trailer creep”
  • Restraining force in excess of 32,000 lbs


The Hold-Tite® is a non-impact, self-aligning, hydraulic vehicle restraint and is available as a standalone unit or integrated with other loading dock equipment through an optional integrated control panel. The unit helps prevent unexpected trailer departure from the loading dock during the loading/unloading process.


Once a trailer is backed into position against the dock bumpers, the operator presses the “Engage” button, activating the Hold-Tite to rotate up and seek out the trailer’s Rear Impact Guard (RIG). The restraint then applies continuous pressure to the RIG to securely hold the trailer to the dock. After loading is complete, the operator presses the “Release” button, lowering the HOLD-TITE unit to a safely stored position, releasing the trailer.


  • Positive hydraulic retention of RIG for zero running room
  • The no shear pin design firmly holds fully loaded or empty
  • trailers after seeking, finding, and securing the RIG
  • Amber caution light when restraint is in process of engaging RIG or in override conditions
  • Integrated iDock Controls for safe leveler interlock
  • Full communication package with signage and interior/exterior red/green lights in opposing mode
  • Restraining force in excess of 32,000 lbs


The Hold-Tite restraint uses advanced iDock Controls with an LED 3-color light communication system. As a truck approaches, the exterior light is green and the interior light is red. Once the trailer is in position and the Hold-Tite is activated, the exterior light will change to red, warning the driver not to pull away, and the interior light to amber while the restraint is in motion and green once the trailer is secured, allowing the dock attendant to safely enter the trailer. When the trailer is released and the restraint is safely stored, the interior light reverts back to red, and the exterior light changes back to green.

If the Hold-Tite is unable to secure the trailer’s RIG due to abnormal trail conditions, the restraint will communicate the fault condition by illuminating an amber “Caution” light on the iDock Controls, or by an optional audible alarm. If “By-Pass” of the system is necessary, it is recommended that you secure the trailer by other means before proceeding with the loading/ unloading process. In “By-Pass” mode the exterior light is red and the interior light is green, accompanied by the amber caution light indicating to the dock attendant to proceed with caution.


The restraint is engaged by a hydraulic cylinder that allows the Hold-Tite restraint bar to securely engage and hold a trailer’s RIG bar. The pump and motor are 1 HP TENV at 115V and the control panel is NEMA 4X with all components, connections, and wiring UL listed and/or recognized. Panels are built in-house in a UL-approved control panel shop.


The durable zinc-plated, steel housing unit is designed to protect the self-contained motor and all internal components from any weather conditions.
