Product Information
The Halcyon Standard Stainless Steel Backplate with harness is machined from high-grade, polished 304 stainless steel. The Standard size measures 26 cm x 39.3 cm (10.25 in x 15.5 in) and weighs 2.22 kg (4.9 lb) as a bare plate, so it offsets buoyant exposure protection while keeping a low, streamlined profile against the back.
Who it is for
This plate suits cold water and drysuit divers, technical divers and anyone building a modular backplate, harness and wing system. The stainless construction adds inherent ballast that can be removed from a weight belt or pockets, which is useful for divers in thick wetsuits or drysuits. The contoured bends and low-profile, ergonomic shape keep the rig close to the body for stable horizontal trim, and the utility holes let the same plate carry accessories as a diver's configuration grows.
Key details
- Material: high-grade, polished 304 stainless steel for saltwater use
- Construction: CNC-machined with individually polished, carefully milled surfaces that eliminate sharp edges
- Shaping: contoured bends and precision slots
- Sizes: Standard 2.22 kg / 4.9 lb, Small 1.83 kg / 4.05 lb, Long 2.52 kg / 5.57 lb
- Dimensions: Standard 10.25 in x 15.5 in, Small 9.10 in x 14 in, Long 10.5 in x 17.75 in
Compatibility and sizing

Halcyon offers the plate in Standard, Small and Long, with harness color and Cinch bolt choices configurable; this listing is the Standard plate with harness, SKU 10.010.100.

Frequently Asked Questions
How do I choose between the Standard, Small and Long Halcyon backplate?
Halcyon offers Standard (10.25 x 15.5 in, 4.9 lb), Small (9.10 x 14 in, 4.05 lb) and Long (10.5 x 17.75 in, 5.57 lb); call 888-701-4017 for fit help.
How much weight does a stainless steel backplate remove from my weight belt?
The bare plate itself provides the ballast: 4.9 lb for the Standard, 4.05 lb for the Small and 5.57 lb for the Long. That stainless mass is carried on your back rather than your waist, which is why Halcyon positions this plate for cold water and drysuit diving where extra ballast is needed. Always confirm your total weighting with a proper buoyancy check.
Will this backplate work with Halcyon accessories like the MC Storage Pak?
Yes. The plate includes utility holes for mating with the Halcyon MC Storage Pak and is compatible with the small Halcyon drysuit inflation kit. It also accepts Halcyon harnesses and Cinch bolt options in 5/16 in or 8 mm. If you are pairing it with a specific wing or accessory, contact us and we will confirm the hardware you need.
Is a stainless steel backplate suitable for saltwater diving?
Yes. Halcyon builds this plate from high-grade, polished 304 stainless steel, a saltwater-appropriate grade, and every surface is CNC-machined and individually polished so there are no sharp edges. As with all dive gear, rinse the plate and harness hardware with fresh water after saltwater use and allow it to dry fully before storage.
