This configuration is common on interior doors, storage rooms, or secondary egress points where exterior key access is not required. The unit ships with a 2-3\/8 inch backset latch, dual radius corner strikes (RCS), and a 5303 full lip strike, giving installers a complete, ready-to-install hardware package. The Matte Black finish suits a wide range of residential door styles. Installation is handled by a licensed locksmith or finish carpenter working within standard residential door prep specifications.\u003c\/p\u003e\n\u003cp\u003eThis deadbolt is suited for residential applications where a single-sided locking function is needed. The included 2-3\/8 inch radius corner latch (RCL) fits standard residential door preparations. The dual RCS and full lip strike are pre-matched to the unit, reducing the need to source additional strike hardware separately. The Matte Black finish is consistent across the trim and hardware components for a uniform appearance.
