Greenfield 220-3 Dwv Hanger Strap 16-gauge 3 Inch

Product Description

The GREENFIELD 220-3 is a plastic-covered DWV hanger strap designed to support horizontal runs of PVC or drain-waste-vent pipe. Constructed from 16-gauge galvanized steel with a 3/4-inch-wide band, it provides reliable load-bearing support while the plastic coating protects the pipe surface from contact corrosion and abrasion. The keyhole fastener slot speeds up installation, and the 12-inch perforated leg allows the strap to be adjusted along the length to accommodate pitched pipe runs without additional cutting or bending. Plumbers and pipefitters working on residential and light commercial DWV systems rely on this strap as a standard support solution.

The GREENFIELD 220-3 is sized for 3-inch iron pipe size (IPS) applications, making it a direct fit for 3-inch PVC, ABS, or cast iron DWV piping systems. The 12-inch perforated leg provides flexibility for installations where pipe pitch must be maintained for proper drainage slope. This hanger is part of a broader product family available in sizes from 1.5 inches to 6 inches IPS, and is also offered without the plastic coating for applications where bare galvanized steel is preferred.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with local plumbing code and IPC requirements for pipe support spacing. Shut off water supply and ensure the pipe run is depressurized before beginning any hanger installation or pipe repositioning. Secure the hanger to structural framing using a fastener appropriate for the substrate, using the keyhole slot for alignment. Verify that the perforated leg is positioned to maintain the required drainage pitch before final fastening.
