The HONEYWELL TR610B is a tulip-style door knob finished in pro satin chrome, designed for bedroom and bathroom doors in residential settings. The interior knob features a turn-button lock that secures both knobs simultaneously, providing straightforward privacy control. An emergency unlock function allows the lock to be released from the exterior using a narrow tool, making it suitable for safety-conscious installs. The knob ships with an adjustable latch that accommodates both 2-3/8 inch and 2-3/4 inch backsets and includes a square face plain latch for a clean installation finish. At 1.117 pounds, the hardware is solid without being cumbersome. This unit is sold individually and packaged in a consumer clear pack.
The TR610B is intended for interior residential door installations, specifically bedroom and bathroom applications where a privacy lock — rather than a keyed lock — is the correct specification. The adjustable backset latch makes it compatible with standard door prep found in most residential construction, covering the two most common backset dimensions without requiring a separate latch purchase. Carpenters, general contractors, and experienced DIYers typically handle this type of hardware installation during new construction, remodel, or hardware replacement projects.
Designed as an OEM-style replacement or new-install privacy knob for standard residential bedroom and bathroom doors with 2-3/8 inch or 2-3/4 inch backset door prep.
Installation is typically performed by a carpenter, finish contractor, or qualified DIYer using a screwdriver and, if modifying the door, a hole saw and chisel. Verify the existing door bore diameter and backset measurement before installation to select the correct latch position. No electrical shutoff or special trade licensing is required for door hardware installation, but local building codes should be consulted for any door modifications.
