I am so glad I found Nelco. You being in the USA is a big bonus as well.
Nelco's Ductmaster™ nylon duct straps are designed for use with flexible air ducts and air connectors allowing for quick and secure installation. Available in lengths from 17.75” to 60”, these duct straps are not only great for using on HVAC ducts, but for use when a longer cable tie is necessary. With a tensile strength of 175 pounds, not only will they hold up HVAC ducts, but these duct straps are great for bundling large cable or wire bundles. These straps have a maximum operating temperature of 185°.
To make installations even easier, use in conjunction with Nelco Products Extra Heavy-duty Air Duct Strap Installation Tool. Part number DM-300.
Ductmaster Duct Strap is UL 181-B-C Approved (UL 181-B-C is molded below the head of the cable tie for easy inspection)
