Diversitech 710-100 Duct Strap 400-460 Lb 100 Yd Polypropylene

Product Description

The DIVERSITECH 710-100 is a woven polypropylene duct strap rated for 400 to 460 pounds of load capacity, designed for securing ductwork, equipment, and mechanical components in HVAC installations. At 1.75 inches wide and 100 yards per roll, this strap gives technicians ample material for a full day of installations or a multi-unit job. The black polypropylene weave resists moisture and holds its strength in the temperature ranges typical of attic and crawl space installs. HVAC installers and sheet metal mechanics reach for this strap when hanging flex duct, rigid duct runs, and air handlers.

This duct strap is suited for residential and light commercial HVAC applications where reliable mechanical support of ductwork is required. It works in new construction framing, retrofit projects, and equipment changeouts. The 100-yard roll length makes it practical for contractors stocking service vans or keeping shop inventory for high-volume installation crews. Typical uses include hanging flexible duct from floor joists or trusses and securing branch takeoffs in attic or basement installations.

Key Features

• 400 to 460 lb load capacity for dependable duct and equipment support
• 100-yard roll length reduces mid-job resupply
• 1.75-inch width distributes load across duct surface to prevent crushing or deformation
• Woven polypropylene construction resists moisture and maintains integrity in unconditioned spaces
• Black finish suitable for exposed or semi-exposed installations

Compatibility

Designed as a general-purpose duct support strap compatible with standard flexible and rigid ductwork installations in residential and light commercial HVAC systems.

Installation Notes

Installation is typically performed by HVAC technicians or sheet metal installers following local mechanical code requirements and SMACNA duct support guidelines. Straps should be fastened to structural members using appropriate hardware rated for the expected load. Avoid over-cinching the strap around flexible duct, as excessive compression reduces airflow area. Power down associated air-handling equipment before working in confined attic or crawl space areas.
