Halcyon Stainless Steel Backplate - STANDARD

By Halcyon Manufacturing | SKU: 10.010.005 | Standard Size | 5.5 lb (2.5 kg) Negative Ballast

Construct your ideal technical or cold-water single-tank setup with the standard of backplate design: the Halcyon Stainless Steel Backplate in Standard Size (10.010.005). Precision laser-cut from high-grade 316 marine stainless steel, this 5.5 lb (2.5 kg) plate delivers critical negative ballast positioned directly along your spine—helping you offload excess lead from your waist belt for flawless horizontal trim in drysuits or thick neoprene setups.

Available at International Diving Centre—Vancouver's source for Halcyon technical gear—this backplate undergoes specialized surface passivating and CNC deburring to guarantee all edges, webbing slots, and mounting holes are silky smooth, protecting continuous harness webbing and wing fabrics from friction wear.
