Cham Interior Door Knob Set

Cham Door Knob Set by Verum 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.

Please note: these are minimal in style. A key design feature is the absence of a rose backplate, making them unsuitable for pre-bored doors.
