B K/mueller Inds(import) 521-604HN Black Floor Flange

Product Description

The B K/MUELLER INDS(IMPORT) 521-604HN is a 3/4 inch black floor flange designed for securing pipe runs to floor surfaces in residential and light commercial plumbing applications. The floor flange provides a stable base mount that anchors vertical pipe or riser sections, preventing movement and maintaining alignment. Finished in black, this fitting is suited for exposed decorative pipe systems as well as standard utility installations. Sold in a package of 10 units, this flange is a practical stocking item for plumbing contractors and supply houses handling multiple fixture or railing installations.

This floor flange is used in applications where a pipe needs to be terminated at or secured to a floor surface. Common scenarios include decorative pipe shelving systems, structural pipe railing bases, gas drop line floor anchors, and exposed plumbing runs. The 3/4 inch size matches standard 3/4 inch nominal pipe thread. Residential plumbers, commercial pipe fitters, and general contractors are the typical installers for this type of fitting.

Installation Notes

Installation is performed by a licensed plumber or qualified pipe fitter. Shut off any supply line pressure before threading pipe into the flange.
