Some doors want a curve. The Quadra doesn't. It's a flat, straight lever on a crisp square rosette — no softening, no rounded edges, just clean geometry sitting flush against the door face. It belongs in a space pulling toward something sharper: a renovation leaning modern, a condo where every line should feel deliberate, a home tired of the rounded builder-grade lever repeated on every door. The square backplate reads architectural rather than decorative, and the flat handle looks like a design choice instead of a default. Built from brass-plated zinc and rated to ANSI Grade 2, the Vellum Hardware Quadra is made for genuine daily use — the chassis holds up to repeated turning without the latch drifting or loosening over time. Choose deeply saturated matte black for contrast or satin nickel for a quieter line, then specify it across all four functions — keyed entry, privacy, passage, and dummy — to carry one geometric language across every door. Reversible handing fits left- or right-swinging doors and standard pre-drilled bores.
