Schlage Electronics 46929178-134 – Frequently Asked Questions

1) What door thickness does the Schlage 46929178-134 mortise kit fit?
It's built for 1-3/4 inch thick doors only. That is the standard commercial door thickness, so it covers most hollow metal and solid core openings in an office, school, or hospital. If your door measures thicker or thinner than 1-3/4 inches, you need the thickness kit matched to that dimension instead, because this one sets the dimensional interface for the mortise lock at a single thickness.
2) Will this thickness kit work with a Schlage CO Series mortise lock, or only AD Series?
Both. The 46929178-134 is listed as compatible with Schlage Electronics AD Series and CO Series hardware, so a facility running a mix of the two platforms can stock the one kit for 1-3/4 inch mortise openings.
3) What does a mortise door thickness kit actually do on the install?
It supplies the correct dimensional interface between the electrified mortise lock body, the trim, and the door face, so the components sit at the right depth and stay aligned once the lock is assembled. Get the wrong thickness kit and the lock case and outside trim don't land square on each other, which is where binding and misalignment on the job come from. It is an installation accessory, not a lock or a trim set, so it does not replace any working part of the lock.
4) What part number do I give my supplier for the Schlage AD Series 1-3/4 inch mortise thickness kit?
Order it as Schlage Electronics model 46929178-134. That is the AD Series mortise door thickness kit for 1-3/4 inch doors, and the same number covers CO Series use.
5) Can I use this kit as a replacement part on an AD Series mortise lock already installed in the field?
Yes, it works either way. The kit is sold both as a component for new AD and CO Series installs and as a replacement or supplemental piece for maintenance on locks already hanging, as long as the door is 1-3/4 inches thick.
6) Is the 46929178-134 kit for an electrified mortise lock or a mechanical one?
It supports electrified mortise configurations on the AD and CO Series platforms, which are Schlage's electronic lock lines. It's a commercial-only part, so it isn't intended for residential mortise retrofits.
