This 4 x 1 in. Primo Sentinel Soft Roll Hollow Spoke Wheelchair Caster assembly will replace 4 x 1 or 4 x 1.5 inch caster wheels found on Quickie, Top End (Invacare), KI Mobility, Motion Composites, and many other wheelchair brands. Some TiLite wheelchairs use 3/8" ID bearings and these caster wheels will not work. Regardless of wheelchair brand, it is always advisable to confirm your size using the guide below.
Measuring your existing wheelchair caster:
Purchasing the proper wheelchair caster is as simple as measuring the old one. Even if the size is written on the existing caster, you still want to make sure the hub width and bearing size will be correct. Properly measuring will ensure you order the correct caster and prevent an installation headache and the hassle of sending them back.
