Several wheelchair makers hold the fork stem bearings in place with a snap ring, also called a C-clip, set down inside the fork or caster mount. These pliers have a right-angle head so the tips can reach into that recess, and a spring that opens the handles between squeezes. The seller names TiLite, Ki Mobility, Frog Legs, Sunrise Medical, Quickie and Zippy as brands that use such rings in some parts.
Suits technicians and home mechanics who replace caster stem bearings or service fork housings. Check whether your fork or caster mount uses a snap ring first, since many designs use a threaded cap or nut instead.

It is a sprung steel ring, also called a C-clip, that sits in a groove and keeps bearings in a fork or caster mount.
The ring often sits down inside the housing, and angled tips can reach it where straight pliers cannot.
No. Only forks and caster mounts built with snap rings need them, so check your part first.
