The HONEYWELL TR810B is a tulip-style privacy door knob finished in antique brass with a steel construction. Designed for bedroom and bathroom doors, it ships with an adjustable latch that accommodates either a 2-3/8 inch or 2-3/4 inch backset using a square face plain latch. The interior knob features a turn button that locks both knobs simultaneously. When locked, the knob can be released from the exterior using a narrow tool — a standard emergency-access function required for privacy sets installed on sleeping and bathing rooms. Locksmiths, finish carpenters, and general contractors are the typical installers.
This knob set is intended for residential bedroom and bathroom door applications where a privacy lock is required without a keyed cylinder. The tulip-style rosette and antique brass finish suit traditional and transitional interior door styles. The adjustable latch simplifies installation across door preparations with either a 2-3/8 inch or 2-3/4 inch backset, making it compatible with most standard pre-hung and retrofit interior door situations.
Designed as an OEM-style replacement or new-install privacy door knob for standard residential interior doors with a 2-3/8 inch or 2-3/4 inch backset preparation.
Installation is performed by locksmiths, carpenters, or qualified general contractors. Before installation, confirm the door bore and backset dimensions match the hardware. Follow local building codes for privacy hardware requirements in sleeping and bathing rooms. Do not force the latch mechanism — ensure the latch face plate is flush with the door edge and the latch engages the strike plate freely before final fastening.
