Anilock stainless steel knob handle - a square knob head on a square tapered stem and a plain square rose, the same form across all three finish codes: BLK, MAE and MSN. Stainless steel throughout for anti-corrosion service, and specified by the supplier for heavy and semi-heavy duty doors. Supplied per piece; the finish codes are the supplier's own. The satin nickel (MSN) knob is the one as photographed; the BLK and MAE images are the same knob shown in those finishes.
