Adams Rite MS1850SN-415-628 – Frequently Asked Questions

1) Will the Adams Rite MS1850SN deadlock fit my narrow stile aluminum storefront door?
That's exactly what the MS1850SN is built for. It's a mortise deadlock for narrow stile aluminum doors, machined to ANSI size door preparation with a 1-1/2 inch backset. The body measures 1 x 6 x 2-1/4 inches, so your stile has to have room for that mortise pocket. If the existing prep in your door is an Adams Rite 1-1/8 inch backset cutout instead, this one won't drop straight in, the bolt centerline moves 3/8 of an inch.
2) Does the Adams Rite MS1850SN come with a cylinder, or do I have to order one separately?
No cylinder in the box. You order it separately, and it has to be a standard 1 inch length, 1-5/32 inch diameter mortise cylinder with the Adams Rite MS cam. That cam is the part people get wrong: a standard mortise cylinder with a straight or clover cam will thread into the housing but won't drive the bolt. If you're keying a building into an existing system, spec the MS cam version in your keyway.
3) Which faceplate do I pick for an Adams Rite MS1850SN, flat, radius, or bevel?
Match it to the edge of the door stile. Flat for a square stile edge, radius for a rounded edge, bevel for a beveled one. All three are orderable, and each comes in every finish offered: 313 dark bronze anodized, 335 black anodized, and 628 clear anodized. Get this wrong and the faceplate sits proud of the edge or rocks on the curve. Look at the existing lock's faceplate or run a straightedge along the stile edge before you order.
4) Is the Adams Rite MS1850SN a Grade 1 deadlock for a commercial building?
Grade 1, and specified as commercial. For an institutional spec sheet calling for Grade 1 deadlocking on aluminum entrances, this meets it. The bolt is eight-ply laminated stainless steel with an alumina-ceramic core, which is the anti-saw construction behind the rating, and the over-center locking action resists forcing in any direction.
5) Do I need to specify handing when ordering an MS1850SN deadlock?
The lock itself is field reversible, but the order does carry a handing option: non-handed, LH or RHR, and RH or LHR. Pick non-handed if you want one part number to cover openings swinging either way across a property. The handed versions exist because the faceplate bevel and edge condition follow the door.
6) What finishes does the Adams Rite MS1850SN deadlock come in, and will it match the rest of my storefront?
Three anodized finishes are orderable: 313 dark bronze, 335 black, and 628 clear. Those are the standard aluminum storefront finishes, so the lock face matches typical dark bronze, black, and clear anodized frames rather than fighting them. Only the faceplate shows once the lock is mortised in, so that's the piece that has to match your other openings.
7) Should I use a deadlock like the MS1850SN or a deadlatch on my aluminum entrance door?
Depends on whether the door needs to close and secure by itself. The MS1850SN is a straight deadbolt, it only throws and retracts when someone turns a key, so it's for after-hours locking on an entrance that's held open or free during business hours. A deadlatch latches automatically every time the door shuts. On a pair of doors, the common setup is a deadlatch on the active leaf for daytime and a deadlock like this on the inactive leaf. If nobody is going to be turning a key at every closing, a deadlock is the wrong function.
8) What else do I need besides the Adams Rite MS1850SN to complete the installation?
Two things beyond the lock body: a mortise cylinder (1 inch length, MS cam) and the strike. The strike side here is a trim plate, so the jamb needs to be prepped for that rather than for a box strike. On a pair of aluminum doors where the bolt throws into the inactive leaf, the trim plate mounts on the mating stile.
9) Can I put an Adams Rite MS1850SN on a hollow metal or wood door, not aluminum?
Yes for hollow metal or wood, provided the door is prepped to ANSI size. The MS1850SN is the ANSI-size version of the MS deadlock, so it goes into an ANSI mortise pocket rather than only the narrow aluminum stile prep. On a standard wood or hollow metal door already cut for a mortise lock, the ANSI prep is what you're working with.
10) How wide is the faceplate on the MS1850SN deadlock?
One inch across, on a body measuring 1 x 6 x 2-1/4 inches. That 1 inch faceplate width is what lets the lock go into a narrow stile without eating the full width of the stile edge, and it's the number to check against your existing cutout if you're replacing a lock rather than cutting fresh.
