Although webbing-type wheelchair tie-downs are preferred where possible, Koller Ratchet Clamps offer advantages for many users. The main benefit is they secure the frame from underneath and not outside the “footprint” of the wheelchair, thus saving vehicle space. Durable in design, they fit most standard size manual wheelchairs.
Koller Ratchet Clamps mount into compatible floor rail via Rail Clip Fittings for easy use and security. A ratchet mechanism is operated via a lever, providing a simple means to tighten the strong hook onto the wheelchair frame. The “Swivel and Tilt” mechanism allows the clamps to fit a variety of wheelchairs. Quick release is provided, enabling the “hook assembly” to slide freely up and down the ratchet bar (this also aids quick positioning of the hook before tightening down).
