A Spherical Knob with an Outside Key Cylinder
Brassera model BRS-DOR-ZNC-004 is a zinc alloy door knob set built around spherical ball knob. Key cylinder sits in center of outer knob face, so door can be keyed from outside. Ball form gives hand round grip to close over, and cylinder face stays level with knob dome. Rose plate carries squared corners with shallow arched shoulder along its top edge.
The set suits bedroom doors, bathroom doors, interior entries in villas, apartments, hotels, offices. Ball profile sits easily beside plain flush doors as well as paneled timber work. Bedroom and bathroom doors are the named uses, and the set also suits hotel guestrooms.
A Bronze Accent Line on the Coffee Bronze Finish
Coffee Bronze is the two-tone option: a thin bronze line traces the knob perimeter and the rose plate edge over a dark body. Matt Black carries no accent line, so its knob and plate hold one uniform black. From a distance the two dark finishes read alike; the line is a close-up detail.
Brush Gold is uniform as well: one brushed gold color across the whole knob and plate, with no accent line. Specifiers can pick two-tone Coffee Bronze or a uniform black or gold from the same series.
Reversible Handing and Two Backsets
Handing is reversible, so one stock part fits a left-hand or right-hand door without field modification. Latch takes either of two standard backsets: 2-3/8 inches (60.3 mm) or 2-3/4 inches (69.8 mm). Doors from 1-3/8 inches to 1-3/4 inches (34.9 to 44.5 mm) thick take assembly. Latch bolt and strike plate ship as part of the set, ready for a bored door. Reversible handing keeps one part number on a mixed corridor, so stock stays simple.
Four functions cover building schedule: Key, Privacy (BK), Passage (PS), Dummy. Keyed sets serve rooms needing a key, privacy sets suit bathrooms, passage sets fit hallway doors, and dummy knobs finish non-latching cupboard leaves.
Inside Turn Button and Supplied Keys
The inner rose plate carries a turn button for locking plus unlocking from inside room. Turning it engages latch bolt, so occupant can set privacy without using key. Outer cylinder takes the key for locking from outside. Multi-unit orders can draw all three finishes from one series.
Keys ship with each set, so a property can hand them out to occupants as soon as doors are hung and keep spares on site. Easy installation is feature named for this set.
Plate Height and Knob Projection
The rose plate stands 2-9/16 inches (65.1 mm) high at single-knob section, with lower section 2-1/8 inches (54.0 mm) wide and upper section 1 inch (25.4 mm) wide. Overall height reaches 3-11/16 inches (93.7 mm). The knob and the rose plate carry the finish named for the set.
Spherical knob measures 1-5/16 inches (33.3 mm) across and projects 1-1/4 inches (31.8 mm) from rose face. Those two figures are what door schedule needs to check clearance against adjacent wall or cabinet return. The adjustable latch fits the two standard backsets, so doors bored for standard tube latches take the set.
An Optional Deadbolt for the Same Door
An independent deadbolt is available for the same door as an optional add-on, not as part of the standard set. A matching deadbolt can be specified for a second locking point; single-bore door needs only knob set.
Each set is packed with foam in an individual inner box, then into outer carton measuring 35 by 28 by 20 cm at 1.5 kg gross. Brassera accepts OEM work for this series, and samples can be arranged before bulk production runs. Carton sizing suits parcel freight for single-set orders on small jobs. Engineering support for larger schedules covers graphic design plus 3D modeling.
