This satin chrome door knob set features a modern, industrial-inspired brushed finish that offers a contemporary alternative to polished chrome, with the added benefit of being more resistant to fingerprints and smudges. Designed for internal doors where locking is not required, the half-sprung mechanism works with lightly sprung latches and is compatible with standard UK tubular latches, making it suitable for replacing existing door knobs. For new door installations, a tubular latch (reference YKTL3N-SN&SC) is required and must be purchased separately. The set includes a pair of mortice knobs, a spindle, and all necessary screws and fasteners, and comes with a 10-year mechanism warranty for long-term durability and reliability.
