Lockscrews & Clamps FAQ

Lockscrew or clamp?

Lockscrews are the simplest and most economical lock for standard (fully recessed) liners. For projected mounting, Carr Lane specifies a round-end clamp. Round and flat clamps are heavy-duty alternatives.

Which lockscrew fits a 1" OD bushing?

Carr Lane lists LS-2 for 1" and 1-3/8" OD renewable bushings, and LS-3 for 1-3/4" and 2-1/4" OD.

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.
