Doubles bands only work as well as the hardware holding them together, and this is the kit Dive Rite trusts for the job. The stainless steel all-thread bolts are sized right for most tank bands, so you're not hunting through a hardware store bin for something close enough. The included thumb wheels let you snug the bands down by hand and break them loose just as easily when it's time to swap cylinders. Toss a set in your save-a-dive kit and you'll never be the diver holding up the boat over a lost bolt.
