Warwick Hanger 3500-100 Perforated Band Strapping 100 Ft

Product Description

The WARWICK HANGER 3500-100 is a 21-gauge carbon steel perforated band iron strapping used to support and hang ductwork in HVAC installations. The roll measures 3/4 inch wide by 100 feet long, providing ample material for multiple hangers on a single job. The plain-finish carbon steel construction delivers consistent strength across the full length of the roll. HVAC technicians and sheet metal mechanics cut the strap to length and loop it around flexible duct, round pipe, or rectangular duct to prevent sag over long horizontal runs. Its perforated design allows secure fastening with screws or bolts at any interval along the strap.

This strapping is suited for residential and light commercial HVAC applications where ductwork requires overhead or structural support. It is commonly used during new construction and renovation work to suspend insulated flexible duct, round metal pipe, and rectangular sheet metal duct from joists, beams, or framing. The 100-foot roll is a standard field quantity that reduces mid-job material runs for installers working on larger duct systems.

Key Features

• 21-gauge carbon steel construction for consistent load-bearing performance across the full roll
• 3/4-inch width with perforations along the full length for flexible fastening placement
• 100-foot roll length reduces material changeovers on larger installations
• Plain finish compatible with standard field fasteners including sheet metal screws and bolts
• Supports flexible duct, round pipe, and rectangular duct in a single product

Compatibility

Designed for use with insulated flexible duct, round pipe, and rectangular duct in residential and light commercial HVAC duct support applications.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal mechanics working under applicable mechanical codes. Power down the air handling system before working in the duct plenum or around energized components near the installation area. Cut strap to the required length using sheet metal snips, and secure to structural framing with appropriate fasteners through the perforations. Follow local mechanical code requirements for hanger spacing, which commonly specify maximum intervals for both flexible and rigid duct runs.
