Adams Rite 2331-626 – Frequently Asked Questions

1) Does the Adams Rite 2331 deadbolt come with a cylinder?
No cylinder is included. You order the 2331 body and supply a mortise cylinder separately, and it has to be a standard 1 inch mortise cylinder with the Adams Rite MS cam so the 360 degree key turn throws and expands the bolt. That is the piece most people forget on the order, and without it the lock will not operate. It also means you can key the 2331 into whatever keyway the rest of the building already runs.
2) How does the expanding bolt on the Adams Rite 2331 hold a sliding door shut with only a 1/2 inch throw?
The throw is 1/2 inch, which is short compared to a conventional swing-door deadbolt, and that is deliberate. The brass bolt carries stainless steel dogs that expand once the bolt is in the strike, so holding power comes from the dogs spreading inside the strike pocket rather than from deep projection. On a sliding door there is very little gap to cross, so a long throw would be useless anyway. Plan the strike alignment tightly: 1/2 inch is all the engagement you get before the dogs do their work.
3) Is the Adams Rite 2331 deadbolt right for a swinging commercial door, or only sliding doors?
This one is built for sliding doors, hollow metal and wood, and for narrow stile aluminum. The expanding bolt and its dogs are what make a slider secure, because a slider gives you no edge to bolt into the frame the way a swing door does. On a standard swinging commercial door you want a conventional deadlock or a mortise lock with a deeper throw into a frame strike instead. Putting the 2331 on a swing door means the expanding dog design is doing nothing you paid for.
4) What does the strike prep look like for the Adams Rite 2331, and how much clearance does it need?
Brass strike, four screws, with a 5/8 x 1-5/8 inch opening the bolt passes through. Door strike clearance is 1/8 inch. That 1/8 inch is the number to check before you order: if the gap between the door and the jamb or receiver is wider than that, the bolt will not sit where the dogs can expand properly, and you will be shimming the strike.
5) What do I need to order besides the Adams Rite 2331 deadbolt itself to finish the job?
Two things beyond the lock. A 1 inch mortise cylinder with the Adams Rite MS cam, because none is supplied, keyed to your system. And the strike, brass, four-screw, with the 5/8 x 1-5/8 inch opening. Add an Adams Rite electric strike instead if the opening is going on access control. The door also needs to be prepped to the 1-3/4 inch backset and the 7/8 x 3-5/8 x 2-5/8 inch case before the lock goes anywhere near it.
6) Will the Adams Rite 2331 fit a narrow stile aluminum door?
Yes, narrow stile aluminum is what it is engineered for, and the case size is why: 7/8 x 3-5/8 x 2-5/8 inches with a 1-3/4 inch backset. The 7/8 inch dimension is what lets it go into a stile that will not take a conventional deadlock body. Hollow metal and wood versions are made as well, so the same 2331 covers mixed openings in one building.
7) What finishes can I get the Adams Rite 2331 in to match the rest of my doors?
Four finishes: 313 dark bronze anodized, 605 bright brass, 625 bright chrome, and 626 satin chrome. 626 satin chrome is the usual match for commercial aluminum and hollow metal openings, and 313 dark bronze anodized is the one that lines up with bronze anodized storefront. If you are standardizing across a building, pick one and specify it on every unit, since the faceplate is the visible part of this lock.
8) Can the Adams Rite 2331 be tied into an access control system?
It works with Adams Rite electric strikes, so the opening can be released electrically while the 2331 still gives you a keyed mechanical deadbolt for after-hours lockdown. The lock body itself is mechanical and key-operated, a full 360 degree turn to throw and expand the bolt, so the electrification lives in the strike, not in the lock. Budget the strike and its power as separate line items.
9) Is there an installation template for the Adams Rite 2331 door prep?
Adams Rite publishes installation instructions and templates for the 2331, and you should mark the door from the template rather than measuring by hand, because the 1-3/4 inch backset and the 5/8 x 1-5/8 inch strike opening have to line up on the bolt path with only 1/8 inch of strike clearance to absorb error. Rout the pocket for the 7/8 x 3-5/8 x 2-5/8 inch case, then test a full 360 degree key turn to confirm the bolt extends, expands, and retracts before you call it done.
