Cambridge 105137 Black Hanging Strap 3in X 300ft

Product Description

The CAMBRIDGE 105137 is a black hanging strap roll used to support and suspend HVAC equipment, ductwork, piping, and related mechanical systems in both residential and commercial installations. The strap measures 3 inches wide and 300 feet in length per roll, providing ample material for large jobs or multiple hangers cut to length on site. This type of perforated hanging strap is a standard fastening and support product installed by HVAC technicians, plumbers, and mechanical contractors during new construction and retrofit work.

This hanging strap is suited for suspending round and rectangular ductwork, pipe runs, unit heaters, fan coils, and similar overhead mechanical equipment. The roll format allows installers to cut straps to the exact length required, reducing waste and accommodating varied hanger depths. It is appropriate for use in light commercial and residential mechanical rooms, attics, basements, and utility spaces where overhead support of mechanical systems is required.

Key Features

• 3-inch width provides broad bearing surface for load distribution across supported components
• 300-foot roll length supports large-scale or multi-unit installations from a single roll
• Black finish for applications where appearance or corrosion resistance in specific environments is a consideration
• Cut-to-length design allows field customization without additional tooling beyond standard snips or shears
• Supersedes legacy part number TRS-HS-3-B for direct replacement procurement

Compatibility

This product replaces part number TRS-HS-3-B. It is a general-purpose hanging strap suitable as an OEM-style replacement or new-installation support component for residential and commercial HVAC, plumbing, and mechanical piping systems.

Installation Notes

Hanging strap installation is typically performed by licensed HVAC technicians or mechanical contractors following local building codes and applicable standards such as SMACNA ductwork support guidelines. De-energize and shut off all associated systems before working overhead in confined or energized mechanical spaces. Use appropriate fasteners rated for the load and substrate — do not substitute fasteners with lower shear or tensile ratings. Ensure hanger spacing meets code requirements for the pipe or duct size being supported.
