Carr Lane UL-20-12 | Un-A-Lok Liner Bushing

Un-A-Lok Liner Bushings

Un-A-Lok Liners are similar to HL head liners, except that they incorporate a sturdy locking tab that eliminates the need for a Lockscrew. UL Liners are permanent bushings used to hold SF renewable drill bushings. Although slightly more expensive than a head liner plus a Lockscrew, installation time is dramatically reduced.
