Schlage L283-605 RX Lock Case, LV9453, Nylon Latchbolt Insert

Schlage L283-605 RX Lock Case, LV9453, Nylon Latchbolt Insert

Refresh a worn mortise lock body with this lock case built for the LV9453 entrance function. It includes an RX request-to-exit (RTE) switch that monitors lever use and can report that action to a security or access control system. A nylon latchbolt insert is also included to help reduce latchbolt interference with an electric strike gate in certain setups.

About this item 

This is a mortise lock case (lock body only) for an LV9453 entrance function setup, with an RX request-to-exit switch and a nylon latchbolt insert.

Function 

The LV9453 entrance function lets the lever retract the latchbolt from either side until an inside thumbturn locks the outside lever, and the thumbturn also throws or retracts the deadbolt while the inside lever remains free for exit.

Applications 

Use this lock case in commercial mortise-prepped doors where you need LV9453 entrance operation and an RX switch signal tied into access control or alarm monitoring.

Best for: 

• Replacing a worn mortise lock body in a Schlage L Series door

• Doors that need LV9453 entrance operation (latch + deadbolt with inside thumbturn)

• Access control systems that need a request-to-exit signal from lever use

It helps by: 

• Restoring normal latchbolt and deadbolt action for the LV9453 function

• Sending an RTE switch signal when lever action occurs (RX)

• Allowing Vandlgard-style lever behavior (outside lever rotates down when locked) to reduce internal damage from hard pulling

• Reducing latchbolt interference with an electric strike gate by using the nylon insert (when applicable)

Key highlights:

• Lock body replacement for Schlage L Series mortise hardware

• LV9453 entrance function logic (latch + deadbolt with inside thumbturn control)

• RX request-to-exit monitoring switch for lever activity

• Nylon latchbolt insert intended to help with electric strike gate interaction (when applicable)
