Hoopster® Retaining Rings

Smalley's Hoopster Retaining Rings offer an innovative way to retain mechanical components when space is a problem. Hoopsters have a minimal radial projection and a shallow groove depth. Hoopsters are available from .375" to 3" or 10 mm to 76 mm in both carbon and 302 stainless steel.

The low-profile Hoopsters are ideal for applications with thin-walled cylinders. The ring ends flex for simplified assembly and removal, with no custom tools required.
