When your Schlage L Series mortise lock needs to work alongside an electric strike, the latchbolt you choose matters more than most technicians realize. The Schlage XL11-422 Solid Latchbolt with Nylon Insert is the OEM replacement latchbolt engineered specifically for compatibility with electric strikes, and it's the correct part for any L Series mortise lock installation where consistent, reliable retraction under electrical control is non-negotiable.

The nylon insert built into this latchbolt isn't just a design choice. It's a functional necessity. In electric strike applications, the latchbolt makes repeated contact with the strike keeper every time the door closes. Without a nylon insert, metal-on-metal contact creates friction, wear, and eventually sticking. The nylon insert reduces that friction dramatically, which means smoother door operation, quieter latch engagement, and a longer service life for both the latchbolt and the electric strike it pairs with.

Why the Right Latchbolt Makes or Breaks an Electric Strike System

Electric strikes release the keeper to allow the latchbolt to pass through, but only when a valid credential or access control signal is received. If the latchbolt has worn down or lacks the smooth, solid profile required to pass cleanly through the strike, you'll see doors that fail to latch completely, strike keepers that bind, and intermittent access control failures that are hard to diagnose without inspecting the hardware itself.

The XL11-422 is a solid latchbolt, not a hollow or spring-latch variant. That solid construction gives it the strength and consistent profile geometry that electric strike systems depend on. If you're troubleshooting an L Series mortise lock that isn't latching or releasing cleanly with the installed electric strike, replacing this part is often the most direct fix.
