Designed by Luca Colombo, the Drop door knob is shaped like a falling drop of water: a smooth, rounded, egg-like grip that fills the palm, set on a round rose. Made in Italy from brass.
Drop comes in Polished Chrome, Satin Chrome, HPS Zirconium Gold and Bronze.
Each Drop knob comes with passage, privacy, keylock, double dummy and single dummy functions. It mounts on a round rose for North American 2 1/8" bored doors, on a heavy duty thru-bolted mortise rose, or on the P300 inter-connected entry and P202 mortise backplates. Privacy sets include the matching thumb-turn and emergency release.
