A Round Crystal Knob on a Round Rose
Clear crystal knob heads draw the eye against circular metal roses on interior doors. A plain round profile keeps to a minimalist reading, with no ornament on the rose face. Smooth round crystal faces stay transparent above the zinc mounting trim.
Brassera model BRS-DOR-ZNC-008 pairs clear crystal knob head with circular zinc alloy rose plate. Round roses seat flat against door faces; each package carries two knob trims plus latch and strike plate. Knob head keeps crystal clear while rose plate, latch face take the finish, so metal reads as one tone per pack.
Matt Black, Bronze, Brush Gold, Brush Nickel and Chrome
Five finishes ship on this door set: Matt Black, Bronze, Brush Gold, Brush Nickel, Chrome. Dark Matt Black stands out on pale door leaves; Bronze carries deep brown undertones for older interiors; Brush Gold brings bright gold tone to hotel doors. Bronze pairs with dark woodwork. Brush Nickel keeps a light silver tone for modern interiors, and Chrome carries the brightest reflectivity of the five.
Strike plates ship in the matching finish with each pack. Uniform rose dimensions let packs from one order sit together along a corridor, and rose diameter, knob diameter and head depth stay fixed across five finishes.
Passage and Privacy Builds for Interior Doors
Passage builds provide non-locking movement across closet doors and interior hallway corridors. Keyless builds carry no lock cylinder, so the door opens from either side with a plain turn of the crystal head.
Privacy builds add occupant locking across private quarters such as bedrooms, bathrooms. Both options keep one visual line through multi-room layouts.
A Push Button Inside, an Emergency Release Outside
Privacy packs carry push button on inside knob. Pressing button locks door from inside; emergency release on outer rose opens it again from outside when a room must be entered. Occupants lock from inside without keys.
