Schlage Electronics 46929178-234 – Frequently Asked Questions

1) What is the Schlage 46929178-234 door thickness kit used for?
It is an installation kit that adapts Schlage Electronics AD Series mortise hardware to a 2-3/4 inch thick door. Standard mortise locks are built around thinner doors, so on a 2-3/4 inch leaf you need the longer spindles and fasteners this kit supplies to keep the trim, spindle and lock body properly aligned and working. Model number is 46929178-234.
2) Will the 46929178-234 kit work with a Schlage CO Series mortise lock, or only AD Series?
Both. The kit is listed for the Schlage Electronics AD Series and CO Series mortise lock platforms, so it covers offline CO Series openings as well as AD Series.
3) My commercial doors are 1-3/4 inches thick. Do I need this Schlage thickness kit?
No. 1-3/4 inches is the standard commercial door thickness and AD and CO Series mortise locks are set up for that out of the box. The 46929178-234 kit is only for doors at 2-3/4 inches, which is a thicker than standard leaf. Ordering it for a 1-3/4 inch door will leave you with parts you cannot use.
4) Can this kit be added to an AD Series mortise lock that is already installed?
It is used for retrofit and upgrade work on existing commercial openings as well as new installs. If you are moving an AD or CO Series mortise lock onto a 2-3/4 inch door, or replacing hardware on one, this is the kit that makes the existing lock body, spindle and trim line up on the thicker leaf.
5) Is the Schlage 46929178-234 thickness kit rated for commercial use?
Yes, it is a commercial door hardware item, intended for AD and CO Series mortise installations in offices, schools, healthcare, government buildings and multi-tenant properties rather than residential work.
6) Do I need one 46929178-234 kit per door?
Yes, one kit per mortise opening. Each kit adapts a single AD or CO Series mortise lock to a 2-3/4 inch door, so a facility standardizing several thick doors needs a kit for each leaf getting the hardware.
