CHANGE TO PRODUCT BULLETIN
P/N 560-111 Locking Collar is Now Made of Stainless Steel with a New Feature

Products Affected: All fiberglass helmet models EXCEPT the SL 17B.

The chrome-plated brass P/N 560-111 Locking Collar will now be made from 316L stainless steel. As stock of chromeplated brass runs low, we will begin switching to stainless steel. Kirby Morgan will install the updated Locking Collars on all future fiberglass helmet production, EXCEPT for the SL 17B.

The new stainless steel Locking Collar for fiberglass helmets features an updated design. A new two-bolt hinge mechanism allows the Locking Collar to stay in place instead of swinging freely like the previous single-bolt design. This enables the Locking Collar to move throughout its range but remain positioned once force is no longer applied.

Service and maintenance for the new two-bolt design are similar to those of the previous single-bolt in both components and servicing procedures.
