Product Information

The Hollis Single Tank Adapter w/ Bolts and Nuts V2 is a single tank adapter (STA) that bolts one cylinder to a backplate and wing system, letting divers switch between single and double tank configurations without restringing cam bands through the backplate and wing. It is built from 316 stainless steel with a laser etched logo and ships complete with the bolts and nuts needed for installation.

Who it is for

This STA suits backplate and wing divers who regularly move between a single tank and doubles setup and do not want to re-thread cam bands every time they switch. It also helps traveling divers who pack their wing and backplate unassembled, since the adapter speeds up rig assembly once they arrive at the destination.

Key details

  • 316 stainless steel construction with a laser etched Hollis logo
  • V2 revision of the Hollis single tank adapter
  • Corrosion-resistant hardware suited to saltwater use
  • Mounts one cylinder directly to a backplate and wing, adding a small amount of ballast low on the diver's back
  • Manufacturer SKU 208.1071.001
