Schlage L283-099 Lock Case Field Reversible

Product Description

The SCHLAGE L283-099 is a replacement lock case designed for use with Schlage L-Series mortise locksets. The lock case is the internal mechanical assembly that houses the latch and deadbolt operating components, translating lever or knob rotation into latch retraction and bolt throw. It mounts inside the door edge cutout as part of a complete mortise lock assembly. Licensed locksmiths and commercial door hardware installers are the primary trades working with this component. A key feature of this case is field reversibility, allowing the handing of the lock to be changed on site without returning the unit to the factory or ordering a separate handed version.

The L283-099 is intended for commercial and institutional door applications where Schlage L-Series mortise hardware is specified. It is compatible with L460, L462, L463, L464, L480, and L496 series mortise locksets. These series are commonly found in offices, schools, healthcare facilities, and government buildings where heavy-duty mortise hardware is required. The field-reversible design simplifies installation on both left-hand and right-hand doors, reducing the need to stock separate handing configurations.
