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.

Optional Track B: School Bus Wheelchair Securement Training

Free Driver Training · Optional Track B

School Bus

Take this track if you drive a school bus or serve as a bus aide for students who use wheelchairs. Your certificate will read Core plus School Bus. Your district, state and each student's transportation plan come first. Reading time: about 6 minutes.

After this track you will be able to:

Explain why school bus securement is different.
Follow a student's transportation plan.
Secure, belt and monitor a student on every trip.

Why school buses are different

School buses behave differently in a crash than vans or transit buses, and school bus securement and restraint systems are built and tested for them. Federal school bus standards (FMVSS 222) and a school-bus-specific test standard (SAE J3027) apply to equipment made for this use. Do not assume equipment made for a van is approved for a school bus. Check the label and the maker's documentation, and ask your transportation department.

Key pointUse only securement and restraint equipment approved for your school bus, installed the way the bus maker and equipment maker direct.

The student's plan

A student's Individualized Education Program (IEP) or similar plan may call for a specific seating position, a particular chair, a harness or positioning belt, a nurse or aide, or a medical protocol. Learn what applies to each student you carry. Student information is private: share it only with people who need it to keep the student safe. If a plan and the equipment do not match, call your supervisor before the bus moves.

Every trip, every student

Secure the chair at four points to the maker's instructions, face the chair as the bus layout directs, and fasten the lap and shoulder belt so it fits the student, as Modules 5 to 7 describe. Ask the family or school what chair accessories, trays and equipment travel with the student, and secure them too. Check that the aisle and emergency exits are clear. A belt cutter and the other safety items in Module 9 should be in the bus.

Safety warningA student's tray, bag, ventilator, oxygen cylinder or other equipment can become a hazard in a sudden stop. Secure everything, and never leave a student unattended on the bus or on a lift.

Emergencies and drills

Practice evacuation with wheelchair users as your district directs. Know who helps, which exit you use and how the chair is released. Report any student injury or equipment problem the same day, in writing.

What the manufacturer saysThe bus maker and the securement maker publish instructions for school bus use. Where this lesson differs, follow them and your district's procedures.
