A UL liner costs slightly more than a head liner plus a lockscrew, but there is no tapped hole to drill and no lockscrew to install, so installation time is dramatically reduced.

How to order UL liners

Un-A-Lok® Liner Bushings (UL) FAQ

Does UL work with the fixed side of an SF bushing?

No. Un-A-Lok liners hold SF renewable bushings on the slip side only. Use a standard liner and lockscrew if you need the fixed side.

What does Quick-Ship mean?

Quick-Ship sizes are the most popular Carr Lane drill bushings, kept in stock at the St. Louis warehouse and ready for same-day shipment. Other sizes in the same series are made to order with a longer lead time.

Can you quote ADB, Boneham or ACTEK equivalents?

Yes. Send the Carr Lane part number or your print and we will quote the matching ADB, Boneham or ACTEK bushing alongside the Carr Lane part, so you can compare price and lead time.
