Backplates are available in aluminum or stainless steel. Some divers prefer stainless backplates due to the fact that they are more negatively buoyant than the aluminum backplates, which helps offset the additional buoyancy of saltwater or aluminum tanks. Aluminum backplates are the most popular with freshwater divers and divers using steel tanks. Dive Rite offers a unique stainless plate with buoyancy characteristics similar to an aluminum plate.

The stainless steel plates are polished and passivated. Passivation treatments improve the surface condition of stainless steel by dissolving iron that has been imbedded in the surface during forming, machining or polishing. Passivation, which consists of immersing stainless steel components in a special acid solution, will dissolve the imbedded iron and restore the original corrosion-resistant surface by forming a thin, transparent oxide film. The aluminum backplates have an anodized finish. Compared to bare uncoated aluminum, the durable anodized aluminum finishes provide greater corrosion resistance and a better consistency in appearance.

All of our plates are of modern laser cut design offering the same basic features:
  • Mounting hole and slot that allows easy assembly on { 11 in | 27.9 cm } centers doubles bolts without alignment concerns.
  • Slots to accept directly threaded tank cam bands for single cylinder diving, making the use of a single tank adapter optional.
  • Horizontal and angled strap slots to allow your choice of straight or cross-over shoulder strap mounting.
  • Both { 1 in | 2.5 cm } and { 2 in | 5.1 cm } slots to accommodate your choice of crotch strap.
  • { 3/8 in | 1 cm } holes along the sides for mounting accessories such as light canisters, inflation bottles and lumbar pads.
  • Rounded corners and all edges are deburred and CNC-machine beveled to reduce wear on the harness and wing.

There is no difference in quality between the various styles and brands we sell, in our long experience they are all equally good quality.

The XT Backplate Pad consists of molded foam contoured to prevent uncomfortable pokes and prods when wearing a metal backplate. Mesh airflow channels provide draining with rapid drying when out of the water and resist compression allowing the pad to maintain its thickness and comfort at depth. Using Velcro straps to secure to the shoulders of a harness, the XT Backplate Pad can be easily added or removed without the need to disassemble the harness and the pad will fit any standard backplate or harness.

Hollis Gear SS Backplate The style 'HG' aluminum and stainless steel backplates from Hollis Gear are both exactly the same shape and size, both are approximately { 15.5 in | 39.4 cm } high and { 10.5 in | 26.7 cm } wide at the base, { 9 in | 22.9 cm } wide at the top before the corner curve. The depth of the "V" is { 1.5 in | 3.8 cm }, allowing for a flatter fit against the back. The { 2 lb | 0.9 kg } aluminum backplate has a durable anodized black finish. The stainless steel backplate has a very highly polished mirror like finish and is slightly lighter at { 4.8 lb | 2.2 kg }. The 'HG' backplate is engineered to fit very close to the cylinders and the outside edges are radius-formed, thus preventing chafing of the BC. One very nice feature of the 'HG' plate is the bottom corners are flared away from the diver so they don't dig in to the lower back. This plate is the version distributed by Hollis Gear.

Interchangability of Backplates and Wings

One configuration consideration is that plates and wings are not always perfectly interchangable among brands. Manufacturers tend to make subtle design decisions such as the placement of grommet holes and slots on the wing based on aligning similar slots and holes of their own brand of backplate. The shape of the flat in the center of a specific brand wing may be designed to match the specific shape of their plate so that the bladder is not pinched by the plate when the two are assembled together on doubles. A common annoyance with doubles mounting is the depth of the "V" in the center of the plate varies slightly among brands, which can trigger compatibility problems with the bolt height setting of the bands. The diver might find it very difficult to engage the wing nuts when assembling a plate and wing on a set of doubles where the bolt height was optimized for a different brand plate and wing.

The good news is that we are not aware of any interchangability issues for doubles mounting between any of the brands of wings and plates we sell. For single tanks, you can usually avoid using a single tank adapter (STA) if the wing and plate are the same brand. By the same token when the brands are mismatched, or the wing manufacturer does not also offer a branded plate, a STA is pretty much a necessity.

For divers who frequently switch their harness, backplate and wing between double tank and single tank rigs, or between backmount and sidemount configurations, the DGX Single Tank Adapter (STA) is a convenient way to attach cam straps to a backplate without having to thread the cam straps through the backplate slots and reweave the cam buckles. Constructed of marine grade passivated 304 stainless steel. There are two lengths of adapter, a standard {15 in | 38 cm} / {1.3 lb | 0.6 kg} version appropriate for most aircells, and a short {11.75 in | 30 cm} / {1.0 lb | 0.45 kg} version appropriate for smaller aircells and travel. The adapters both include all stainless hardware consisting of pairs of both { 1 in | 2.5 cm } and { 1.5 in | 3.8 cm } long 5/16-18 thread carriage bolts (with some backplates the longer bolts are needed) on { 11 in | 27.9 cm } centers, washers, and wing nuts, along with two rubber pads to protect the tank. Does NOT include Tank Straps.

Single Tank Mounting with Backplates

  • If you occasionally switch between doubles and singles, you can configure your backplate (including the soft backplates of the TransPac and Nomad) to attach to a single tank by adding two tank straps threaded through the tank strap slots of the backplates. Note that when a traditional metal backplate is off the tank, the wing will hang loose on on the straps. This is cosmetic and does not otherwise cause problems, but if you wish you can use two plastic assembly screws to hold the wing against the backplate. Omitting the STA also reduces weight.

  • If you frequently switch between doubles and singles, you may prefer the speed and convenience of adding the straps using an optional single tank adapter mounting plate. Using an STA means the strap buckles never have to be unthreaded and re-weaved plus the STA also holds the wing in place with the plate when off the tank and adds weight to the rig. Some backplate and wing designs include provisions for tank strap slots, but if you have an backplate or a wing design without the tank strap slots then you must add straps using a single tank adapter.

We are often asked if the tank mount would be more stable and secure using the STA, as opposed to threading the cam straps directly through the backplate. We've tested several configurations and discovered that threading the straps through the backplate is at least as stable as when using an STA. Using an STA sets the tank farther away from the backplate and allows the tank to rock slightly by pivoting from side to side on the bolts. Using the straps threaded to through the backplate snugs the tank and wing up very tight against the backplate and does not allow the tank to rock.

Finally, although a common practice we do not recommend transporting your wing sandwiched between a backplate and single tank adapter, they should be disassembled to individual components with the soft goods packed separately from the hard metal components. The hard edges of the plate and STA if stored together with the wing and if subjected to ordinary impact could puncture the bladder inside the wing and cause a leak.
