Schlage Electronics 46929178-214 – Frequently Asked Questions

1) What door thickness does the Schlage 46929178-214 AD Series mortise thickness kit cover?
The 46929178-214 kit is sized for doors that measure 2-1/4 inches thick. It is a single-thickness kit, so if your slab is a standard 1-3/4 inch commercial door you do not need it at all, and if the slab is a different oversized thickness you need the matching kit for that dimension instead.
2) Will this thickness kit work with Schlage CO Series mortise locks, or only AD Series?
Both. The 46929178-214 is built for Schlage Electronics AD Series and CO Series mortise lock products, so the same kit covers either family on a 2-1/4 inch door.
3) Does the 46929178-214 kit fit cylindrical Schlage AD locks?
No. This one is for mortise configurations in the AD Series line. A cylindrical AD chassis on an oversized door needs the cylindrical-specific thickness kit, not the mortise part.
4) What exactly is a door thickness kit, and why do I need one for an electronic mortise lock?
It is an installation accessory that compensates for door thickness variation so the mortise lock seats and aligns correctly on a non-standard slab. Electronic mortise locks are built around one nominal door thickness; on a thicker door the through-fixings and reader housing no longer line up without the compensating parts. The 46929178-214 supplies that compensation for a 2-1/4 inch door.
5) I am standardizing AD Series mortise locks across a building with mixed door thicknesses. Can I order one kit for all of them?
No, these kits are thickness specific. The 46929178-214 covers only 2-1/4 inch slabs, so survey each opening and order the kit that matches that door. Openings at standard commercial thickness take no kit at all.
6) Does the 46929178-214 include the lock itself?
No. It is an accessory kit only, supplying the parts needed to fit an AD or CO Series mortise lock to a 2-1/4 inch door. The mortise lock body, trim, credential reader and cylinder are all ordered separately.
7) Is the Schlage 46929178-214 kit meant for residential doors?
It is a commercial part. Schlage lists the 46929178-214 as commercial only, which matches where you find 2-1/4 inch slabs: office buildings, schools, hospitals, government facilities, hotels and industrial openings with heavy door construction.
