Sure-Lock Lock Rings Lets you make precise adjustments of all standard 7/8″-14 dies and accessories.

LOCK RING: Clamps around the whole die. Can’t damage the threads. Applies constant pressure across the threads to hold the ring in place. Most other die rings lock by jamming a set screw directly into the threads.

WRENCH FLATS: Remove and replace dies without pliers ruining the lock ring.
