Cham Interior Door Knob Set
Cham Door Knob Set by Verum Italy departs from traditional round forms, defined by its soft square profile and refined edge detailing. With a gently rounded front face and subtly beveled corners, Cham balances crisp geometry with an approachable tactility. Installed flush to the door with no rose required, Cham is part of Verum's Nuda collection — a minimalist, contemporary solution that emphasizes both ease of installation and elevated design. Made in Italy.
A key design feature is the absence of a rose backplate, making these handles unsuitable for pre-bored doors.
