The 9/16-inch wide band and the screw assembly of this value priced clamp are both stainless steel. This is an "American-style" clamp where the grooves in the band are perforated completely through the band. This grade clamp is widely used in automotive hose clamping applications, although not usually seen in all stainless steel. Popularized in diving for use with hogarthian (aka DIR) stage strap assemblies, when using these inexpensive automotive hose clamps for securing cylinder stage straps you must avoid using the strap as a carry handle otherwise properly tightened clamps will eventually move and the strap will loosen. Over tightening the clamps in an attempt to prevent the strap from loosening will damage the clamp by either breaking the grooves or stripping the screw.

This sheathed clamp version includes tubular webbing that covers the band and a slightly wider piece of tubular webbing that covers the screw assembly. Once a cylinder clamp has been tightened on to the cylinder, the long tail of the metal clamp typically protrudes at an angle and may interfere with handling of the stage bottle or even cutting exposure suits. The primary primary purpose of the nylon tubular webbing sheath is to provide a cover to manage the excess tail of the clamp once it has been tightened on to the cylinder. Recommended for use with the "American-style" clamps where the hard edges of the band and housing may rub against the exposure suit. The webbing is hot knife pre-cut to appropriate length to match the diameter of the cylinder.

X-Small sheathed clamp fits cylinders approximately {4.40 in | 11 cm} in diameter (AL-13, AL-19)
Small sheathed clamp fits cylinders approximately {5.25 in | 14 cm} in diameter (AL-30, AL-40, LP-45, LP-50)
Large sheathed clamp fits cylinders approximately {7.25 in | 18 cm} in diameter (LP-72, LP-80, AL-80, HP-80, LP-85, HP-100)
X-Large sheathed clamp fits cylinders approximately {8.00 in | 20 cm} in diameter (LP-95, AL-100, LP-104, HP-119, HP-130)

NOTE: We only offer 2 sizes of stainless steel clamps but offer 4 sizes of tubular webbing sheaths for a more precise fit when attached to the correct size cylinder.
