Our STA has been re-sized to fit squarely in the opening of our Travel and Voyager series wings. For divers who frequently switch between double tank and single tank rigs, our single tank adapter is a convenient way to attach cam straps to a hard metal backplate that does not have tank band slots. Constructed of marine grade 304 stainless steel. Includes two rubber non-slip cam strap pads and all hardware required to mount STA to a backplate.
