Warwick Hanger 584663 Perforated Band Strapping 21 Gauge

Product Description

The WARWICK HANGER 584663 is a perforated band iron hanger strap made from 21 gauge carbon steel, designed to support flexible duct, round pipe, and rectangular duct in HVAC systems. At 0.75 inches wide and 10 feet long, each length provides enough material to span typical joist or rafter spacing while maintaining reliable support. The plain-finish carbon steel construction handles the mechanical loads of suspended ductwork across extended runs. HVAC installers and sheet metal mechanics reach for this strap when hanging duct in residential and light commercial applications where sagging over long runs is a concern.

This hanger strap is suited for use in forced-air HVAC installations where flexible duct, spiral round pipe, or rectangular sheet metal duct needs to be secured to framing members. It is especially useful in attic, crawlspace, and basement installations where duct runs span several feet between support points. The perforated pattern along the strap allows field trimming and fastener placement at multiple locations without the need for additional drilling, speeding up the hanging process.

Key Features

• 21 gauge carbon steel construction provides consistent load-bearing strength for suspended ductwork
• Perforated pattern allows flexible fastener placement without field drilling
• 0.75 inch width suits standard duct hanger brackets and framing fasteners
• 10-foot length gives installers material for multiple hangers from a single piece
• Compatible with flexible duct, round pipe, and rectangular duct
• Plain finish suitable for interior, conditioned, or semi-conditioned spaces

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. Secure the strap to framing members using fasteners appropriate for the substrate, following SMACNA duct support guidelines for spacing intervals. Power down the HVAC system before working in confined spaces with active ductwork. Do not overtighten straps around flexible duct, as compression can restrict airflow through insulated flex.
