The Schlage 47858868 is the OEM indicator sign insert displaying the "UNLOCKED / LOCKED" message for Schlage ND Series indication trim locks. It's the physical sign panel that sits inside the indicator trim window on the lever escutcheon and shows the current lock status to whoever is on that side of the door. When the indicator trim window becomes faded, cracked, scratched from cleaning chemicals, or unreadable from years of high-traffic use, this sign insert replaces it directly without disassembling the full lock from the door.

This is a different product from the 47858867 Vacant/Occupied indicator sign. That sign uses occupancy-focused language for privacy lock functions in restrooms and patient rooms. The 47858868 uses security-focused language for keyed entrance, office, corridor, and Vandlgard functions where what matters is whether the lever is currently locked or unlocked, not whether a space is in use.

Schlage Indicator Lock Functions That Use the UNLOCKED/LOCKED Sign

The 47858868 is confirmed for use in eight ND Series indicator trim configurations. For outside indicator models, it covers the ND40 bath/bedroom privacy with outside indicator, the ND44 hospital privacy lock with outside indicator, the ND52 keyed privacy lock with outside indicator, and the ND55 entrance lock with outside indicator. For inside indicator models, it covers the ND50 entrance/office lock with inside indicator, the ND53 entrance lock with inside indicator, the ND91 Vandlgard entrance/office lock, and the ND92 Vandlgard entrance lock.

Why the UNLOCKED/LOCKED Message Matters on These Functions

On entrance, office, and Vandlgard lock functions, the critical information for building staff and occupants isn't whether someone is inside the room — it's whether the door is currently in a locked or unlocked state. In a school, a teacher activating the inside push button or turning the inside thumbturn to lock the classroom door needs immediate visual confirmation that the lock is engaged. The IS (inside) indicator trim on the ND50, ND53, ND91, and ND92 provides that confirmation from inside the room so the occupant doesn't have to test the lever to verify.

On outside indicator functions like the ND52 keyed privacy lock, the OS (outside) indicator tells approaching staff or security whether the space is currently locked from inside, which matters in any setting where controlled access verification happens at the door.

Schlage Indicator Lever Trim Technical Specifications

The ND Series indicator trim uses a high-density polycarbonate viewing window that wraps three sides of the escutcheon, providing Schlage's patented 180-degree visibility. The indicator message runs the full width of the lock at a height of 0.6 inch, making it readable from across a hallway. Red and white messaging backgrounds are used specifically for color-blind accessibility — the color shift between locked and unlocked states is legible regardless of color vision deficiency.

Indicator trim is standard for 1-3/4-inch door thickness. Sold-separate spacer kits allow application on doors from 1-3/8 inch to 1-11/16 inch. All Schlage ND Series cylindrical locks with indicator trim maintain UL 10C fire door certification and ANSI/BHMA Grade 1 certification.
