Diamond Knurl Locking Liner Bushings

A liner for cast-in-place or potted instalation, used to hold Slip/Fixed Renewable drill bushings, Un-A-Lok liners incorporate a special locking tab that eliminates the need for a lockscrew. Holds only the "slip" side of a Slip/Fixed bushing, not the "fixed" side. Diamond-knurled OD provides superior holding strength against both rotational and axial forces. Since the bushing's OD is not ground, keeps the ID accurately located during casting or potting to ensure accuracy in the finished tool.
