The HONEYWELL DB9X21 is a steel single cylinder deadbolt finished in brushed nickel, designed for residential door security applications. The unit features a 1-inch hardened throw bolt that resists forced entry and meets standard residential door prep requirements. A key cylinder on the exterior retracts the bolt from outside; a turn piece on the interior operates it without a key. The latch is adjustable and interchangeable between 2-3/8-inch and 2-3/4-inch backsets, accommodating the two most common door bore configurations without requiring separate parts. Installation is handled by locksmiths and general contractors working residential door hardware.
This deadbolt is suited for standard residential entry doors where a single cylinder configuration is required. The square face latch plate fits typical door edge preparations. The unit uses the Kwikset keyway, making it compatible with existing Kwikset-keyed hardware on a job site for potential keying consistency. When ordered by the case of 24 units, the product ships with 4 sets of 6 keyed-alike cylinders, simplifying key management on multi-unit residential projects or property management accounts.
Designed as an OEM-style replacement or new-installation deadbolt for standard residential entry doors prepared for single cylinder deadbolt hardware. Uses the Kwikset keyway as stated in product data.
Installation is typically performed by a licensed locksmith or qualified contractor following the door hardware manufacturer's template and local building code requirements. Power down any associated electronic access systems before working on the door assembly. Use the included adjustable latch to confirm the correct backset before securing the faceplate. Do not over-tighten mounting screws, as this can bind the bolt mechanism and affect smooth operation.
