- ID RANGE - 3/16 - 1

Similar to a Head Liner Bushing, but incorportaing a special locking tab that eliminates the need for a lockscrew. Un-A-Lok liners are permanent bushings used to hold Slip/Fixed Renewable Drill Bushings (on the "slip" side only, not the "fixed" side). Although slightly more expensive than a head liner plus a lockscrew, installation time is dramatically reduced.
