DND · Knob

Quadro

DND technical division

A square-faced knob from DND's technical division — geometric counterpart to Easy and Sfera. Polished and satin chrome. The square geometry sits flush against modern flat-stock millwork — the rosette, the knob face, and the door panel all read as a single composition.

Configure the finish

Satin Chrome

Every DND knob is available across the palette shown. Per-finish photographs aren't always published — the form stays consistent, the finish is what changes. Ask us for finish-specific renders or samples.

Choose function

Passage rosette

Latch only — no locking mechanism. The knob turns the spindle and retracts the latch. Specified for hallways, closets, pantries, and pass-through doors that never need to lock.
