if i have a 15L steel cylinder and i want to attach it to my elite 2 harness and backplate using the S series (single tank). would you recomend the 7.25" or the 8" bolt kit?
Brett H The bolt kit is for mounting Dual cylinders with stainless bands on them to a backplate setup like yours. You will not use these for a single tank setup. If you have an S series wing from hollis all you need is some cam bands or you can use a single tank adapter if you like.
