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.
