The 5/8-inch wide band and the screw assembly of Dive Gear Express cylinder clamps are both stainless steel. There are no spot welds to rupture, and the one-piece housing cannot come apart. The particular design is engineered to tolerate an exceptional amount of torque on the worm drive, the downside being the size of the screw assembly and housing are slightly larger than typical.

The Small clamp fits diameters from approximately { 3.5 in | 9 cm } up to { 5.5 in | 14 cm } and the Large fits diameters from approximately { 5 in | 13 cm } to { 8.5 in | 22 cm }. We recommend the small clamp for 4.4-inch and 5.25-inch scuba cylinders and the large clamp for 7.25-inch and 8.0-inch scuba cylinders.
