Is your trailer restraint system ready for tomorrow's challenges?
Traditional loading dock environments demand more from workers and equipment as traffic becomes more dynamic and the flow of goods expands. Rite-Hite's RHR-1100 Dok-Lok is the industry's most versatile trailer restraint, offering total dock safety for a wide variety of applications and customer's needs.
So what about tomorrow? Its future-focused design is ready. If you anticipate your dock's needs will change as business evolves, you're covered with ease of upgradeability to Shadow Hook technology — which is exclusively designed to restrain the widest variety of RIG-based trailers.
- Rite-Hite's original "rotating hook" design brought a new level of safety to loading docks, creating the vehicle restraint industry in 1980.
- OSHA formally recognized the Dok-Lok as an alternative means to its wheel chocks standard (29 CFR 1910.78) in 1981.
- RHR-1100 is designed with an exclusive third-generation rotating hook that provides the most wrap in the industry, capturing outdated ICC bars, standard 4x4 and pentagonal RIGs to help prevent trailer separation accidents.
- The removable hook mask is designed for ease of Shadow Hook upgrade, which allows the restraint to safely engage intermodal container chassis and obstructed RIGs.
- Backed by Rite-Hite's 12-Month Limited Money-Back Guarantee of Customer Satisfaction. Standard Warranty includes 3-year parts / 1-year labor. Rite-Hite Extended Warranty includes 5-year parts / 3-year labor and connected capabilities.

Is your restraint designed and built with a focus on loading dock safety?
The material handling industry reports more than 100,000 annual forklift accidents. Proper RIG engagement paired with constant restraint status communication helps prevent certain trailer separation accidents, including:
- Trailer creep
- Early departure
- Landing gear collapse
- Trailer pop-up
All Dok-Lok vehicle restraints come standard with red and green lights to communicate to drivers when it’s safe to back in or depart, and to dock workers when it’s safe to perform loading or unloading operations. Your vehicle restraints should also feature or support future integration of solutions that address trending pedestrian hazards that often occur outside on the dangerous drive approach and inside the loading dock.

Are you getting full value from your vehicle restraint?
Product Specifications:
- Exclusive Barrier Design
- More wrap than competitive vehicle restraints to help maintain RIG engagement, especially in below-dock end load situations.
- Third-generation machined steel hook with zinc dichromate finish provides industry-leading wrap for outdated ICC bars and 4x4 pentagonal RIGs.
- Ease of upgrade to latch-free, Shadow Hook cover that creates a 5" vertical barrier for obstructed RIGs
- Spring-loaded structural hardened steel housing automatically positions when a backing trailer contacts the unit.
- Engagement range extend from 9" to 30" above the ground, with the option for a 9" or 12" carriage.
- Standard on 9" carriages, the dual articulating nose extension ensures widest range of coverage and helps protect the SHR-5100 from potential damage when servicing RIGs lower than 22"
- Reliable Performance
- Dual clad track with 50% more track strength helps minimize damage for heavy loading environments or aggressive pull-out attempts.
- If the hook is challenged while in operation, auto-re-fire technology helps to restore a safe, secure engagement.
- All Dok-Lok vehicle restraints are certified to meet and exceed ANSI MH30.3 performance testing standards.
- Integrity of Installation
- The enclosed, 5/16" (8mm) welded steel is designed and installed with (15) 5/8" wedge style anchor bolts and 22" of weld to front curb angle to receive the impact of trailers backing into position.
- Completed dock survey required for each dock position to help ensure safe and proper application of all Dok-Loks®.
- Rite-Hite's Standard Warranty includes 3-year parts / 1-year labor.
- Extended Warranty includes 5-year parts / 3-year labor.
- Pull-Out Force Benchmarks
- Rite-Hite was the first loading dock equipment manufacturer to establish pull-out force benchmarks based on years of research and development.
- All Rite-Hite restraints installed with more than 100,000 lbs. of mounting force and 32,000 lbs. of pull-out force — double what tractors can achieve in first gear.
- Built for Harsh Environments
- Military grade corrosion resistant finish on rotating hook track, base plate and housing maintains aesthetics while reducing the risk of rust for longer-lasting units. Successfully endures 1,000 hours of salt spray testing — compared to only 100 hours for galvanized restraints.
- Mounted above ground away from dirt, debris, snow, ice and standing water.
How clear is your communication at the loading dock?
Rite-Hite's communication systems enhance Dok-Lok safety by clearly informing dock personnel when they can safely enter or exit a trailer - and truck drivers when they can depart after loading or unloading.
Operated from a NEMA 4x interior panel, the RHR-1100's standard Dok-Lok controls and Dok-Commander Combined Controls can interlock into a safe sequence of operations to help protect people, products and equipment by reducing human error and equipment faults.
- Auto-Light Package
- Optional feature for this manual restraint activates red and green flashing lights automatically when engaged or disengaged
- Two auxiliary LED light brackets mounted to upper corners on interior loading dock doors provide immediate line-of-sight vehicle restraint status to material handlers entering trailer.
- Mitigates risk of control box sight obstruction from pallets, personnel and forklifts.
- Leveler-Vu™
- Two auxiliary LED lights mounted alongside the loading dock leveler pit, provides immediate line-of-sight for Dok-Lok vehicle restraint status to material handlers exiting trailer.
- Reduces unnecessary forklift traffic and miscommunication.
- Pedestrian-Vu™
- Addresses forklift-pedestrian accidents, which account for 80% of all reported forklift accidents by extending the forklift's blue light.
- Detects activity inside trailer with mounted sensors and emits intense blue light onto the leveler when motion is detected, communicating that dock personnel should proceed with caution.
- Can be interlocked with any Dok-Lok to help prevent disengagement for added safety and sounds alarm if unrestrained trailer is entered.
- Approach-Vu™
- Visual and audible warning system activated by presence of backing vehicle in the drive approach, indicating need for pedestrians to safely vacate due to potential threat.
- Available as standalone for facilities with simple wheel chocks or competitive units or embedded in VBR-350 housing.
- Lok-Vu™
- Lock verification system that utilizes an outside camera and inside monitor to show dock personnel when trailer arrives and is safely engaged or disengaged, reducing number of processes out on the dangerous drive approach.
- Dual camera option allows dock personnel to also confirm trailer stand presence in the case of spotted (dropped) trailers.
- Dok-Lok® Dock Timer
- Real-time display of active or total (un) loading duration for each dock position, helping improve loading efficiency by increasing capacity and trailer throughput.
- Integrate with trailer presence sensor to track duration from trailer arrival to Dok-Lok engagement via Rite-Hite ONE while also helping to keep boots off the ground to verify trailer arrival.
Want more visibility into dock performance for safety and productivity?
Dok-Lok Vehicle Restraints are Rite-Hite ONE-enabled. Connecting to this single Digital Platform provides real-time visibility and data to empower maintenance decisions, reduce inefficiencies and help mitigate safety events.

- Dok-Lok overrides and/or fault modes.
- Employee entering an unrestrained trailer.
- Dock door open but safety barrier not deployed.
- Productivity. Analytics gathered during each step of the loading process to identify bottlenecks and optimize operations, such as:
- Total duration of loading, to help avoid detention costs.
- Equipment utilization to determine under- or - over-usage.
- Trailer at dock but restraint not yet engaged.
- Uptime. Visibility into connected equipment status and service history, such as:
- Designate equipment state (out of service or immediate repair service required)
- Equipment performance trending down (cycle counts, use, service history)
- Document and log maintenance and services events
