Replacement part for:

• Post 2007 AP BCDs
• AP Back Mounted Counterlung Harness (BMCL) (waistband only - see below for the shoulder straps)

Back Mounted Counterlung Harness (BMCL)

Please note: The BK12A Fastex double adjustable buckle is used on the waistband of the AP Back Mounted Counterlung Harness but the BK12 is used on the shoulder straps.

For 50mm single-adjustable Fastex buckles see BK12 on this site. The BK12 is used with AP (BUDDY) BCDs (pre 2007) and the AP Over-the-Shoulder Counterlung Harness  (at both shoulder and waist).

Please Note: You cannot mix a BK12 male with BK12A female clip (or vice versa), they have different male / female connectors.
