The Square door knob is a flat square cap with gently pinched sides on a short square neck, set on a square rose, designed by Luca Colombo. It is a fixed knob: it does not turn or operate a latch, and is used as a single dummy on doors that are held closed by a catch, such as closets and pantries. Made in Italy from brass.
Square comes in two sizes: Small (LC25, 2.17 Inch knob) and Large (LC35, 2.76 Inch knob).
Square comes in Vintage Matte, Matte Graphite, Vintage, Satin Chrome and Polished Chrome. Vintage and Vintage Matte are available in the Small size only.
Each knob is sold singly, for one side of the door.
