The B K/MUELLER INDS(IMPORT) 521-606HC is a 1-1/4 inch black floor flange used to anchor pipe to a floor or base surface in plumbing and structural pipe applications. The flange provides a stable, flat-mount connection point for vertical pipe runs and is sized for 1-1/4 inch pipe. Finished in black, it is suited for exposed installations where appearance and corrosion resistance in dry environments are considerations. This type of fitting is typically installed by licensed plumbers or general contractors working on pipe support, drain, or decorative pipe frame assemblies.
Floor flanges in this size see regular use in residential and light commercial plumbing rough-in, pipe railing fabrication, and industrial pipe support systems. The 1-1/4 inch size accommodates standard Schedule 40 pipe and fits common applications where a secure floor-mount termination is required. This product is sold in a package quantity of 12 units, making it practical for contractors outfitting multiple connection points on a single job.
Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch pipe floor-mount applications in standard plumbing and pipe support systems.
Installation is typically performed by a licensed plumber or qualified contractor. Before installation, ensure the pipe and mounting surface are properly prepared and all water supply lines in the work area are shut off as applicable. Fasten the flange to the floor using appropriate anchors or fasteners for the substrate material. Follow all applicable local plumbing codes and IPC guidelines for pipe support and anchoring requirements.
