Hercules offers 3 distinct types of hanger strap, which is generally used in hanging ductwork and flex. The heavy duty commercial strap is available in 18 and 22 gauge, and is supplied in 1" x 10 foot strips.  22 gauge strap is available in a 400 foot roll.  Lighter 26 and 30 gauge strap is available in either 1" or 1.5" widths, with 100 foot rolls in a convenient, small box. We also carry plumber's strap (a.k.a. holey iron) in a 50 foot length.
