The Halcyon Cinch adaptor plate is a high-quality injection molded assembly that attaches to your back plate.

The plate has an accessory attachment slot on each end as well as two holes that affix the plate to your backplate. A series of slanted slots match the harness slots on the Halcyon back plate. A specially designed riser creates a slick surface that allows your webbing to slide freely when needed but to remain secure while standing up with tanks on your back.
