Schlage Electronics 46929178-218 – Frequently Asked Questions

1) What does the Schlage 46929178-218 door thickness kit actually do?
It is an installation accessory that adapts Schlage Electronics AD and CO Series mortise lockset hardware to a 2-1/8 inch thick door. Standard commercial mortise hardware is set up for thinner doors, so on a 2-1/8 inch leaf you need the matching thickness kit to get the lock components to seat and operate correctly. It is not a lock and it contains no lock body or trim.
2) My doors are 1-3/4 inches thick. Do I need the 46929178-218 kit?
No. The 46929178-218 kit is built specifically for 2-1/8 inch thick doors. At 1-3/4 inches, the standard commercial door thickness, an AD or CO Series mortise lock is supplied to fit as is, and adding this kit would put you out of spec. Measure the leaf first and order the thickness kit that matches the actual measurement.
3) Will the 46929178-218 thickness kit work with a Schlage AD Series cylindrical lock?
No. This kit is for mortise lock configurations of the AD and CO Series. Cylindrical chassis locks use a different thickness accommodation, so a mortise kit will not help you there. Confirm your lock is the mortise version before ordering.
4) Can I use this kit on a retrofit, or is it only for new AD Series installs?
Both. The kit is intended for retrofits, replacements, and new installations where a non-standard 2-1/8 inch door thickness has to be accommodated with AD or CO Series mortise hardware. Property managers swapping older mortise locks on thick commercial leaves are the usual case.
5) If I order the 46929178-218, do I still need to order the lockset separately?
Yes. The 46929178-218 is a thickness kit only, an accessory to an AD or CO Series mortise lockset. The lock body, trim, cylinder, and strike all come with or alongside the lockset itself. Order the lockset in the function and finish you need, then add this kit to suit the 2-1/8 inch door.
6) Is the Schlage 46929178-218 kit rated for commercial use?
It is a commercial-grade accessory, classified for commercial door hardware rather than residential. Typical applications include office buildings, schools, healthcare facilities, government buildings, retail, and multi-tenant residential with commercial doors.
