Product specification

CD12-R-PSS4-30412 x 6" deep, 12 gauge, all type 304 (CF8) stainless industrial floor drain, round top, with loose set anti-tilt extra-heavy-duty perimeter drainage cover, 1/2" top plate frame, perforated removable bucket basket with lift handle, pre-sloped bottom sump, and pre-pour concrete stabilizing anchor ring.

Why control pathogens?

Floor drains "breathe": moving water within a drainage system creates aerosols that can rise out of drains and be carried by air currents to surrounding areas. Since pathogens can survive in drains, these aerosols can carry them up and into the production environment — so stainless steel drains must be readily accessible for routine inspection, cleaning, sanitation and environmental swabbing.

Don't let your time and money go down the drain. Built to last a lifetime.
