Product Description
The Schlage 48029970 is the ND Series indicator spacer kit that adapts a status-indicator ND lockset to a thin door. Schlage builds the ND indicator chassis around a standard 1-3/4" door. When the opening is thinner — a 1-3/8" to 1-1/2" door, common on older interior partitions, closets, and light commercial millwork — the indicator trim and chassis need this spacer kit to sit correctly and read cleanly. This is the 1-3/8" to 1-1/2" door thickness kit in 626 satin chrome.
What this kit is for
If you are installing or servicing a Schlage ND indicator lock (the ones with the LOCKED/UNLOCKED, OCCUPIED/VACANT, or IN USE window) on a door thinner than 1-3/4", the indicator mechanism will not seat properly without the correct spacer stack. This kit supplies the spacers and hardware to close that gap so the indicator aligns, the through-bolts land, and the trim sits flush. Match the kit to the door: this one covers the 1-3/8" to 1-1/2" band. Thicker sub-standard doors use the 48029971 kit; the thinnest band uses 48029972.
Where it fits
Schlage ND Series indicator functions — ND40, ND44, ND50, ND53, and the ND indicator status-indicator variants. It is a genuine Allegion / Schlage service part (Indication Components family), not an aftermarket substitute. If you are not sure which thickness kit your door needs, measure the door leaf at the lock edge and match to the band.
