Floor Anchorage Options

Floor anchorages allow QRT-550 retractors to be directly mounted to the vehicle floor, seat legs or barriers.


For applications that use L-Track or L-Pocket anchorages, QRT-550 retractor kits include our patented Positive Lock Indicator (PLI) that clearly indicates when the fitting is locked in the anchorage.


For applications that use Slide ‘N Click anchorages, QRT-550 retractor kits feature a single-bolt SNC assembly and plunger that features a full 360º rotation, eliminating anchorage alignment guesswork.

QRT-550 Features & Details 

Securing Today’s Heaviest Wheelchairs

Dynamically sled tested with wheelchairs up to 200kg.

Fully Meets WC18/19

Meets load requirements of up to 60% higher during a collision as specified by RESNA & the WC18 standard. The QRT-550 is also fully compatible with newer WC19 Wheelchairs.

Stronger Than All Other Retractors

The QRT-550 utilises an innovative energy management design and new energy-absorbing steel frame to deliver the system’s full strength for maximum load capacity.

New Webbing & Teeth

QRT-550 is the only retractor to feature double (2) high-strength 58mm webbing loops and 25 interlocking teeth, that combine to allow for super fine adjust self-tensioning.

All New Redesigned Heavy Duty Flat Hook

The heavy duty flat hook provides maximum strength and makes it easy to secure virtually any device. This hook also reduces the twisting of belts.

Automatic Self-Tensioning & Locking

Our industry-leading self-tensioning retractors automatically take up slack to ensure wheelchair passenger is always secured. The belts continue to tighten during low-g vehicle movements, reducing the potential for dangerous excursions in the event of a collision.

Positive Lock Indicator for L-Track

For L-Track and L-Pocket applications, the QRT-550 boasts a re-engineered PLI for an even clearer, more precise indication that the fitting is locked in the anchorage.

Accommodates Larger Wheelchairs

QRT-550 features a smaller retractor footprint than traditional securement, allowing for better placement flexibility and accommodation of large wheelchairs and scooters.

Enlarged Foot Release

The foot release of the QRT-550 has been enlarged, making it easier to engage.


Constructed from hardened steel and coated in zinc for maximum corrosion resistance.

Low Profile

No mounting bracket allows QRT-550 retractors to fit under most footrests.

Compatible Floor Anchorages

L-Track, Slide ‘N Click
