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.
