I designed this cover to replace loose or damaged covers on round recessed wall boxes while still allowing cables to exit when needed. The inner ring inserts into the box and the outer flange covers the surrounding opening.

Important

This is a mechanical cover, not a certified electrical enclosure component. Verify fit, cable protection and electrical clearances. The recessed geometry was designed with support material in mind.
