Several years ago, Cambridge Resources emerged as an industry powerhouse in the Flex Duct Support Management market with the introduction of our high quality Support Webbing, complementing our Heavy Duty Duct Strap line.

We have custom engineered state-of-the-art extruding technology to weave the very finest quality Support Webbing that meets or exceeds every industry standard. Cambridge’s Support Webbing is UL certified as to the heat release rate and smoke optical density, and registers a remarkable tensile strength of up to 640 lbs.

Our UL certified Heavy Duty Duct Straps, manufactured within our ISO-9001:2001 production facility, are rated for operating temperatures -40°F to 185°F (-40°C to 85°C). To ensure superior performance, Cambridge’s nylon Heavy Duty Duct Straps products should be stored in a sealed polyethylene bag at room temperature in at least 50% humidity (recommended 80% RH). Limit the exposure of unused Heavy Duty Duct Straps to extreme heat and cold. Should Heavy Duty Duct Straps be exposed to extreme temperatures and/or extreme relative humidity, store at room temperature and at least 50% humidity (recommended 80% RH) for at least 24 hrs in a sealed bag prior to further use.
