Thermoplastic pipe hangers were originally developed in Switzerland in the 1950’s in Zurich Switzerland. It was a revolutionary invention that was designed to replace steel equivalents and improve installation efforts and labor units by using plastic pipe hangers.

The small family controlled company, Litchfield International, Litchfield CT created the original category of thermoplastic pipe hangers   for this same product in 1984 for North America.

The thermoplastic hanger category created a new type of construction hardware used first in residential construction followed by commercial and industrial applications. The applications grew from electrical conduit systems to telecommunications and cable systems, to pipe systems for plumbing, heating, refrigeration.

Piping, plumbing, refrigeration applications: engineered piping systems, pvc pipe, cpvc pipe, pex tubing, stainless steel tubing, copper tubing, ppr piping, pvdf piping. All systems are used with thermoplastic pipe hangers

Strut systems: Attach to strut systems with LT109 Strutcatcher using both thermoplastic pipe hangers or just plastic pipe hangers
