L400 Small Case Mortise Deadbolt Indication Trim

Made to fit a small cutout, L400 locks feature the same large indication windows of standard L Series so you can Know It's Locked™ when security or privacy matters.

Overview

Part of the L Series family, these non-lever deadbolts offer strength in a small case mortise chassis design. Five of the six L400 Series functions enable the use of Schlage's patented 180-degree visibility indication trim. The sixth comes with a chevron shaped indicator as part of the design. 

Ideal for use on:

  • Doors where latching is not required
  • Multi-stall restroom entrances (for maintenance or lockdown purposes)
  • Private areas like lactation rooms, dressing rooms, or showers
  • Retail or other spaces with occupancy load of 300 or less where a double cylinder deadbolt with status indication is desired

Schlage's Visual Indication Trims were named winner in the Lock and Door Hardware category for the 2024 Campus Safety BEST Awards
