Schlage L9010 05A 643E Mortise Lock Aged Bronze

Product Description

The SCHLAGE L9010 05A 643E is a Grade 1 passage latch mortise lock designed for commercial and institutional door hardware applications. This unit ships with the 05 lever style mounted on an A rose trim and finished in 643E Aged Bronze. A passage latch function means the lever operates freely from both sides with no locking mechanism, making it suitable for hallways, corridors, and interior passages where unrestricted access is required. The Grade 1 rating reflects the highest ANSI/BHMA performance classification for heavy-duty cycle life and durability. The lock body is field reversible, allowing installation on left- or right-hand doors without special ordering.

This mortise lock is suited for commercial interiors including office corridors, hotel hallways, healthcare facilities, and educational buildings where a non-locking passage function is required. The 05 lever and A rose combination provides a clean, traditional profile that integrates with standard commercial mortise lock preparations. Locksmiths, commercial door hardware installers, and general contractors typically handle installation on new construction or retrofit projects.
