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 bushes used to hold SF renewable drill bushes (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 bush refers to its overall length not including locking tab, not its length under the head. Patent no. 3,015,242 and 3,099,079.
