The 9/16-inch wide band and the screw assembly of Dive Gear Express cylinder clamps are both stainless steel with a durable one piece housing and NO spot welds.

• The small size clamps are approximately {23 in | 58 cm} long for diameters from { 3.5 in | 9 cm } up to { 6.5 in | 17 cm }. This is most 4 inch and 5 inch cylinders such as the LP50, AL8, AL13, AL19, AL20, AL30, AL40, FX15, and FX23. It will NOT fit the tiny AL6.
• The large size clamps are approximately {28 in | 71 cm} long for diameters from { 5 in | 13 cm } to { 8.5 in | 22 cm }. This is all 7 inch and 8 inch cylinders such as the LP85, AL72, AL80, HP80, HP100, HP117, HP120, and HP130.

Once snugged to the cylinder, the clamp will always have some excess 'tail' remaining. If this is a concern, you can tuck the excess inside the webbing sheath or trim off the excess. If you trim the excess, the remaining edge may be sharp so be prepared to also file the end a little to make it smooth.
