FEATURES: Similar to an HL head liner, but incorporating a special locking tab that eliminates the need for a Lockscrew. UL Un-A-Lok® Liners are permanent bushings used to hold SF 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. Note: the "length" listed for an UL bushing refers to its overall length not including locking tab, not its length under the head. Patent no. 3,015,242 and 3,099,079. STANDARD SIZES: See Dimensions page for part numbers. The prices shown apply to standard bushings only, as listed in the table, either ground or unground OD.
