Kingston Brass BSFK4410SS Watercourse 4" Square Brass Shower Drain, Polished Stainless Steel

I ordered several of the Kingston Brass Watercourse drains and installed the one I liked the best. The square grate ones all have a hidden round strainer/hair-catcher. The grate lifts out without tools, yet doesn't wiggle around at all when in place. Then you just lift out the round stainless strainer that catches the hair. The only difference between all the different square grate drains in the Watercourse series is the visual design of the cut-outs. They also make a larger size grid in some designs, but I don't know anything about that one because I didn't order it. It has surprised and amazed every plumber and contractor who has seen it!
