Schlage Electronics 23599384-134 626 – Frequently Asked Questions

1) What door thicknesses does the Schlage 23599376-138 door thickness kit cover?
The 23599376-138 kit is ordered by the door thickness it adapts to, and the choices are 1-3/8, 1-3/4, 2-1/4, 2-1/2 and 2-3/4 inches. Pick the option that matches the measured thickness of the door leaf at the lock prep, not the frame. 1-3/4 inch is the usual commercial door; 1-3/8 inch shows up on older interior openings, and the 2-1/4 through 2-3/4 inch options cover thick doors where the standard hardware hardware fasteners and spindles come up short.
2) Which Schlage locks does the 23599376-138 thickness kit work with?
It is made for Schlage Electronics AD Series and CO Series door hardware. If you are installing a CO Series electrified lock, or an AD Series unit, on a door outside the standard thickness the lock ships prepared for, this is the adaptation kit for that opening. It is not a kit for mechanical-only Schlage cylindrical or mortise lines.
3) Do I need a door thickness kit for a standard 1-3/4 inch door with a CO Series lock?
Usually not. Schlage AD and CO Series hardware is built around the 1-3/4 inch commercial door, so the kit matters when the door is thinner (1-3/8 inch) or thicker (2-1/4, 2-1/2, 2-3/4 inch). A 1-3/4 inch version of the kit is offered for cases where an installer needs the replacement fasteners and parts for that thickness, but on a normal 1-3/4 inch opening the lock's standard hardware is what you use.
4) Does the Schlage thickness kit come in a finish to match my lock trim?
There are finished versions as well as a plain Standard option. 626 Satin Chrome is offered at 1-3/4 inch, and 643E Aged Bronze at 2-1/4 and 2-1/2 inch. The Standard (unfinished) option covers 1-3/8, 2-1/4, 2-1/2 and 2-3/4 inch. If any part of the kit shows on the door face, order the finish that matches the CO or AD Series trim already on your other openings.
5) I manage a building with thick solid-core doors. Can I still standardize on Schlage CO Series access control?
Yes. Thickness is the usual blocker on those openings, and the 23599376-138 kit exists to handle it, with options up to 2-3/4 inches. That lets you spec the same CO Series electrified lock across the property and just change the thickness kit per door instead of switching hardware lines on the thick openings.
6) Is the Schlage 23599376-138 a lock, or just the adapter parts?
Just the adapter parts. It is a door thickness kit, an installation accessory that adapts AD or CO Series hardware to a given door thickness. The lock chassis, trim, and credential reader are ordered separately as the CO or AD Series device itself.
7) Is this thickness kit a residential part or rated for commercial use?
Commercial. The 23599376-138 is an installation accessory for commercial access control work, and it turns up in office buildings, schools, healthcare, government facilities, multi-tenant residential, warehouses and retail. It is not sold as a residential-grade item.
