Installation & Operation

Adams Rite MS1850SN-455-628 – Frequently Asked Questions

1) Will the Adams Rite MS1850SN-45X hookbolt deadlock fit my narrow stile aluminum storefront door?
Narrow stile aluminum doors are what the MS1850SN-45X is cut for. The lock case is 1 x 6 x 2-1/4 inches and mortises into the stile, and the backset is 1-1/2 inches, so your stile has to be prepped for that backset. Adams Rite also builds the MS series in a 1-1/8 inch backset for tighter stiles, so measure from the door edge to the centerline of your existing cylinder hole before you order. If that measurement comes back at 1-1/8, the 1-1/2 backset version will not line up.
2) Does the MS1850SN-45X deadlock come with a cylinder, and which cylinder do I need?
No cylinder is included. You order it separately, and it has to be a mortise cylinder with the Adams Rite MS cam, 1 inch length and 1-5/32 inch diameter. Any standard Adams Rite MS cam mortise cylinder works, which is what lets a locksmith key it into an existing system. A conventional 1-1/8 inch mortise cylinder with a standard cam will not retract this hookbolt.
3) Why use a hookbolt deadlock instead of a straight deadbolt on a sliding door?
A sliding door fails by parting, the leaf pulls away from the jamb rather than swinging. A straight deadbolt only resists that with the length of its throw, and a pry bar can walk the door off it. The hook-shaped bolt on the MS1850SN-45X rotates out and catches behind the strike, so pulling the door away pulls the hook tighter into the keeper. That is the reason to spec a hookbolt on hollow metal or wood sliding doors and on narrow stile aluminum pairs, rather than a conventional deadbolt.
4) Which faceplate do I order for a beveled or rounded aluminum door edge?
Match the faceplate to the edge you actually have. The MS1850SN-45X ships in three faceplate profiles: flat, radius, and bevel. Flat suits a square edge stile, radius suits the rounded edge common on aluminum entrances, and bevel suits a beveled door edge. Get this wrong and the plate sits proud of the stile. All three profiles are available in every finish offered.
5) Is the Adams Rite MS1850SN-45X a Grade 1 lock for a commercial spec?
Grade 1, and built for commercial service. The bolt is eight-ply laminated stainless steel with an alumina-ceramic core, which is the anti-drill element a spec writer is usually after on an exterior storefront or a facility perimeter door. If your drawing calls for a Grade 1 narrow stile hookbolt deadlock, this meets that line.
6) Do I have to specify handing when ordering the Adams Rite MS1850SN-45X?
You can go either way. The deadlock is field reversible, and it is sold both as a non-handed unit and as handed units, LH or RHR and RH or LHR. If you are stocking for a building with mixed openings, the non-handed version keeps one part number on the shelf for every door. If you are matching a specific opening and want it out of the box ready, pick the handed one.
7) What prep does the frame need for an Adams Rite MS1850SN-45X, and is a strike included?
The hookbolt needs a routed strike slot in the metal jamb, not just a surface keeper, so the frame gets machined as part of the install. On the door side the case pocket takes the 1 x 6 x 2-1/4 inch lock body and the faceplate covers a 1-1/4 x 8 inch area of the stile. The strike side is handled with a trim plate. On a retrofit into an existing storefront, check that the jamb has enough clear depth behind the face for the hook to swing into before you commit.
8) Can the MS1850SN-45X be operated with a thumbturn from the inside instead of a key both sides?
Either arrangement works. The deadlock takes 360 degree key or thumbturn operation, and the key only comes out when the bolt is fully thrown or fully retracted, so nobody walks away leaving it half locked. On an egress opening, confirm your local code allows a keyed cylinder on the inside before you spec key both sides; a thumbturn inside is the usual answer on a door people exit through.
9) Can I standardize the whole building on the Adams Rite MS1850SN-45X across different door edges and swings?
Yes, and that is the practical case for it. One model covers flat, radius, and beveled stile edges, both hands plus a non-handed unit, and three anodized finishes, so a portfolio of storefront and sliding openings can run on a single Grade 1 deadlock with one keyway family. Since every unit takes a standard Adams Rite MS cam mortise cylinder, a facility can key the entire set into one system and keep one spare cylinder type on the shelf.
10) What finishes does the Adams Rite MS1850SN-45X hookbolt deadlock come in?
Three anodized finishes are orderable: 313 Dark Bronze Anodized, 335 Black Anodized, and 628 Clear Anodized. Those are the aluminum storefront standards, so on a building where the door frames are already dark bronze or clear anodized the lock face disappears into the stile. Each of the three is available with a flat, radius, or bevel faceplate and in non-handed or handed form.
