EXF BL-FK-4IN-BK 4.37" Matte Black Shower Fixture

Square Shower Drain 4.37 Inch

The EXF BL-FK-4IN-BK is a square shower drain measuring 4.37 inches with a 2 inch central outlet. It is designed for bathrooms, kitchens, garages, balconies and basements. The matte black finish uses 304 stainless steel for corrosion resistance. The ABS flange fits standard U.S. plumbing connections.

High Flow Without Filter Mesh

The drain operates without a filter mesh to maintain high flow capability and prevent ponding during sustained use. The seamless grid grate enhances water flow continuously. The embedded design provides an invisible look while the rubber collar secures the drain to the flange without leakage. The adjustable thread adapter allows height adjustment up to 1 inch for consistent performance.

Adjustable Height With Thread Adapter

Installation uses the included threaded adapter to adjust the drain height up to 1 inch. The rubber collar secures the square drain to the ABS flange to prevent water leakage. A lifting key is provided to remove the drain cover for cleaning. The kit includes drain body, base, hair trap, adapter, collar and lifting hook. Buyers who need a linear drain format cannot use this square model.
