The Hollis Back Plate is engineered to fit closer to the cylinders preventing GAPEOSIS, creating a tighter profile and as a result reduces drag. The edges on the outside of the Hollis Stainless Steel Back Plate are radius formed to fit the Hollis BC, thereby preventing back plate chafing of the BC. The webbing that passes through the slots in the back plate must continue to function throughout the dive season without appreciable abrasion.
The slots, holes and edges of the Hollis Back Plate are fully de-burred eliminating sharp edges that can cut you and your harness system.
Back plate can be used with single or double cylinder set ups.
