Cut as much strap as you need to hang duct, pipe, and other materials.

Perforated straps have mounting holes, so there’s no need for drilling. Straps that have two mounting-hole diameters have alternately spaced large and small mounting holes.

Flexible hangers create custom-sized loop hangers when they’re wrapped around pipe and round duct. Rigid hangers are often used in combination with fasteners and clamping hangers to extend hanging length. They can also be bent and fastened as part of a system to support the bottom of duct, pipe, or tube.

Galvanized and zinc-plated steel straps have good corrosion resistance. Copper-plated steel straps resist corrosion when used with copper tubing. 304 stainless steel straps have excellent corrosion resistance.
