Bulletin # 7 of 2015

This lock nut was used only in the very first, original model Hood & Keeper Kit (ref. Bulletin #4 of 2003). The original model Band Keepers became obsolete March 2004, no longer requiring the 530-145 lock nut. A much easier & efficient band keeper kit was introduced late April 2004 (ref. an “All Dealer Faxed Notice May 11, 2004). Locknuts were shipping with hoods as an assurance that anyone still using the original keepers receive a new lock nut (an extra was also included) for the bottom band keeper when changing the hood. The 530-145 nut is a one-time use only lock nut.

If some customers do still happen to be using the original band keepers, they may purchase replacement lock nuts.

No other part number changes. No price changes at this time.

Kirby Morgan strongly recommends the use of band keepers on all KMB 18 and 28 BandMasks®:

525-172 Band keepers with hood,
525-121 Band keeper Kit, No Hood.
