B K/mueller Inds 511-604HN 3/4 in Galvanized Floor Flange 20 Pack

Product Description

The B K/MUELLER INDS(IMPORT) 511-604HN is a 3/4 inch galvanized floor flange used to anchor pipe runs to floor surfaces in residential and commercial plumbing installations. The galvanized steel construction provides corrosion resistance in exposed or semi-exposed environments. This fitting accepts standard 3/4 inch threaded pipe and is fastened through the base plate to the floor substrate. Plumbers and pipefitters install this flange when securing pipe risers, handrails, or structural pipe assemblies to concrete, wood, or metal subfloors. The 511-604HN ships in a package quantity of 20 units, making it suitable for multi-unit jobs or contractor stocking.

This floor flange is used in residential and light commercial plumbing rough-in work, as well as in structural pipe applications such as pipe handrails, shelving uprights, and equipment mounting frames. It is compatible with standard 3/4 inch NPT threaded pipe. The galvanized finish makes it a practical choice for utility spaces, mechanical rooms, garages, and other areas where bare steel would be exposed to moisture.

• Galvanized steel construction for corrosion resistance in damp or utility environments

Compatibility

Installation Notes

Installation is performed by licensed plumbers or general contractors depending on application. Secure the base plate to the floor substrate using appropriate fasteners for the material — concrete anchors for slab, wood screws for subfloor. Thread the pipe into the flange hub hand-tight, then wrench-tighten; use thread sealant tape or pipe compound on all threaded connections. Shut off the water supply and depressurize the system before installing in any active plumbing line.
