In our experience, the plastic versions also work every bit as well as the metal versions for mounting accessories to backplates and they are much lower cost. Designed to fit through a 3/8-inch hole. Sold as a set of two.

We STRONGLY suggest using these plastic options to help attach your aircell to a hard metal backplate as they lay flat and will not interfere with your cylinder.

Without the assembly screws, when the BCD is taken off a single tank the wing will hang loose on the cam straps. Note that this function is just cosmetic, some people prefer to omit the assembly screws and this does not cause a problem.
