What is a 4-point wheelchair tie-down system?

A 4-point tie-down uses four retractors or straps — two at the front and two at the rear of the wheelchair — to secure the chair to the vehicle floor. When combined with a lap and shoulder belt for the occupant, it meets federal ADA and WC18 securement standards for paratransit, NEMT, and school bus transport.

Is wheelchair securement required by law?

Yes. The Americans with Disabilities Act (ADA) requires that all public transit vehicles equipped to transport wheelchair users must have an approved securement system. NEMT providers, paratransit operators, and school bus fleets are all subject to federal and state securement regulations. Failure to comply can result in fines and significant liability in the event of an accident.

What does WC18 compliant mean?

WC18 is the RESNA/ANSI standard that defines performance requirements for wheelchair tie-down and occupant restraint systems (WTORS). WC18-compliant products have been crash-tested to withstand higher load forces than previous standards, providing greater protection for wheelchair users in the event of a collision or sudden stop.

Which wheelchair securement brands do you carry?

We are an authorized dealer for Q'Straint, AMF Bruns, and Sure-Lok — the three leading manufacturers of wheelchair tie-down and occupant restraint systems worldwide. All products meet or exceed WC18 compliance standards where applicable.

What is the difference between an L-track and a Slide N' Click system?

L-track is a recessed floor channel that accepts fittings at any point along its length, giving installers maximum flexibility in retractor placement. Slide N' Click is Q'Straint's proprietary system using pre-set anchor points that allow faster, tool-free securement — popular in high-volume paratransit operations where speed of securement matters.

What is the difference between a manual and retractable wheelchair strap?

Manual straps are fixed-length webbing straps with a hook or loop connection — simple, affordable, and reliable. Retractable systems use a spring-loaded mechanism to automatically take up slack, making securement faster and reducing trip hazards from loose webbing. Electric retractors add powered retraction, ideal for operators or drivers with limited hand strength or mobility.

Do you offer fleet pricing for multiple vehicles?

Yes. We offer fleet pricing for operators outfitting five or more vehicles. Submit your vehicle count, vehicle type, and preferred brand through our Fleet Quote form and a specialist will respond within one business day.

Do your products come with installation instructions?

Yes. All products ship with manufacturer installation guides. We also maintain a full library of installation and user guides on our website for Q'Straint, AMF Bruns, and Sure-Lok products. Our specialists are also available by phone at 800.884.6456 if you need installation support at no charge.

The AMF Bruns PROTEKTOR 2.0 SilverSeries 4-Point WTORS Kit with Retractor Shoulder Belt is a complete, fleet-grade wheelchair occupant restraint system built for high-demand paratransit, NEMT, and accessible transit operations. This kit pairs four automatic PROTEKTOR 2.0 SilverSeries wheelchair retractors with a manual pelvis lap belt and an automatic retractor shoulder belt featuring a manual height adjuster — giving operators precise, per-passenger positioning every trip.

Unlike static shoulder belt kits, the H370255 retractor shoulder belt self-stows when not in use, eliminating loose webbing and reducing boarding time. The integrated manual height adjuster accommodates passengers from children through adults in a single hardware setup. All four wheelchair retractors mount to L-Track via L-Track fittings, with J-Hook wheelchair attachment, while the shoulder belt mounts top-and-bottom to L-Track via a 90° bracket — a fully track-based system requiring no bolt drilling into vehicle structure.

Frequently Asked Questions

How is the retractor shoulder belt different from a static shoulder belt?

The H370255 is an automatic retractor — the shoulder belt winds itself back into the housing when not in use, keeping the vehicle interior tidy and reducing trip-over risk for drivers and passengers. A static shoulder belt hangs fixed in position and must be manually managed. For high-volume routes with frequent passenger changes, a retractor shoulder belt significantly reduces boarding and deboarding time. The manual height adjuster is an additional advantage: you can reposition the belt for each passenger without removing or replacing hardware.

Does the shoulder belt require L-Track on the wall or ceiling?

No. The H370255 mounts exclusively to floor-level or side-wall L-Track via L-Track fittings on both the top and bottom of the unit, with a 90° bracket at the retractor body. No overhead or ceiling track section is required. The L-Track floor rail used by the four retractors (included in K530311-0000HL) is the only track infrastructure this complete kit requires.

Can this kit accommodate passengers of different heights?

Yes. The H370255 shoulder belt includes a manual height adjuster that allows the upper anchor point to be repositioned for shorter or taller passengers — from pediatric to large adult — without changing any hardware. The H450199 lap belt features dual-side adjustment with extended webbing (+12") for a broad fit range. Together, these two occupant restraints make this kit well suited to mixed-population routes.

What is the warranty coverage for this kit?

The PROTEKTOR 2.0 SilverSeries retractors (K530311-0000HL) carry AMF Bruns' 3-year limited warranty — the longest coverage in the PROTEKTOR lineup. The H370255 shoulder belt and H450199 lap belt each carry a 1-year limited warranty. Warranty details and registration information are available at amfbrunsamerica.com/support/warranty.
