This kit converts a flush mount Universal Stopper to surface mount.
Constructed from tough polycarbonate, this kit includes a clear conduit spacer, mounting gasket, two conduit gaskets and four conduit knockout fills (for use when conduit is behind wall and not exposed on surface).
When used outdoor, this spacer (with a conduit gasket) will accommodate 1/2" conduit. For indoor applications, where no conduit gasket is required, this spacer will accommodate 1/2" and 3/4" conduit.
