Adams Rite MS1890-2016-628 – Frequently Asked Questions

1) Will the Adams Rite MS+1890 deadlock fit my narrow stile aluminum storefront door?
That's exactly what the MS+1890 is built for. It's engineered for narrow stile aluminum doors, with a lock case measuring 1 x 7-3/8 inches plus depth, so the stile only has to swallow a 1 inch wide case. Hollow metal and wood door options are also offered. Standard door thickness for the prep is 1-3/4 inches. Pick the backset to match your stile depth: 31/32 inch, 1-1/8 inch, or 1-1/2 inch.
2) What is the difference between the deadlock and the deadlatch function on the Adams Rite MS+1890?
It does both, and that's the point of the plus in MS+1890. The hookbolt gives you maximum security deadlocking for after hours. During business hours you run it as a deadlatch so the door latches on close without anyone throwing the bolt. On the cylinder, a 360 degree turn projects and retracts the hookbolt, and an additional 120 degree turn works the latchbolt. If you only need after hours security and no daytime traffic control, a straight deadlock without the latch function is the simpler part.
3) Does the MS1890 come with a cylinder, or do I have to buy one?
No cylinder is included. The MS+1890 takes a standard Adams Rite MS cam mortise cylinder, ordered separately. If you're keying a building into an existing system, that's where the keyway decision gets made, not on the lock body. Budget for the cylinder on every opening you're doing.
4) Is the Adams Rite MS+1890 handed, and how do I tell which one I need?
Handing matters here. It's ordered as either Left Hand / Right Hand Reverse or Right Hand / Left Hand Reverse. Stand outside the door, on the key side: if the hinges are on your left it's a left hand or right hand reverse opening, hinges on the right is the other. Get this wrong and the hookbolt throws the wrong way for your jamb.
5) Which bolt shape do I pick on the Adams Rite MS1890 for a center hung door?
Four bolt shapes are offered and the choice follows your door hanging and jamb. Flat/Center Hung 4 inch Jamb and Flat/Center Hung 4-1/2 inch Jamb are the center hung options, and you pick between them on your actual jamb width. Flat/Standard Jamb covers an offset hung door into a standard jamb, and Radius/Standard Stile is for a radius stile. Measure the jamb before ordering a center hung version, since the 4 and 4-1/2 inch bolts are not interchangeable.
6) Can a hookbolt lock like the Adams Rite MS+1890 be cut or pried open?
The bolt is eight-ply laminated stainless steel, 5/8 by 1-3/8 inches, with an alumina-ceramic core inside it to defeat a hacksaw. The hook shape is what handles the other attack: it wraps the strike, so a pry bar spreading the door and frame has nothing to push the bolt out of. Throw is 13/16 inch. It's a Grade 1 commercial lock.
7) What strike do I need with the Adams Rite MS1890 hookbolt?
An armored strike. On a hookbolt you can't reuse a plain deadbolt strike, because the hook has to catch and hold inside the frame, and the strike has to be aligned to both the deadlock bolt and the latchbolt positions. Plan on preparing the frame for it as part of the install rather than dropping the lock into whatever is already there.
8) Everything I have to specify to order an Adams Rite MS+1890 correctly?
Five things get chosen and all five have to be right: backset (31/32, 1-1/8, or 1-1/2 inch), bolt shape (flat standard jamb, radius standard stile, or flat center hung for a 4 or 4-1/2 inch jamb), faceplate (flat, bevel, radius, or radius with weatherstrip), finish (628 clear, 313 dark bronze, or 335 black anodized), and handing (LH/RHR or RH/LHR). Then add the MS cam mortise cylinder, which does not come with the lock.
9) Will the 13/16 inch throw on the Adams Rite MS1890 reach my existing strike?
Throw is 13/16 inch on a bolt measuring 5/8 by 1-3/8 inches. That is a hookbolt, not a straight deadbolt, so it isn't just a question of reach: the hook swings out and catches behind the strike, and it needs the armored strike prepared for it. Reusing a straight deadbolt strike pocket won't hold the hook. Plan the frame prep with the lock.
10) Which faceplate should I order on the Adams Rite MS1890?
Four faceplates: flat, bevel, radius, and radius with weatherstrip. Match it to the stile edge you're cutting into. A flat stile takes the flat or bevel plate, a radius stile edge takes the radius plate, and the radius with weatherstrip version is the one to order on an exterior pair where the meeting stile carries weatherstripping you don't want to fight. This is a separate selection from the bolt shape, so specify both.
11) Can I put the MS+1890 on an access control system with an electric strike?
Yes, it's compatible with Adams Rite electric strikes, so the deadlatch side of the lock can be released electrically for card or intercom entry while the hookbolt stays as the manual after-hours lock. That's the usual arrangement in retail and office buildings that want controlled daytime access and a hard mechanical lockdown at close.
12) What finishes does the Adams Rite MS+1890 deadlock come in, and will it match my storefront?
Three anodized finishes to match aluminum storefront: 628 Clear Anodized, 313 Dark Bronze Anodized, and 335 Black Anodized. Those are the standard storefront colors, so on a building where you're replacing one lock in a run of doors, match the existing frame color rather than the old lock's plating. The faceplate is a separate choice: bevel, flat, radius, or radius with weatherstrip.
13) Is the Adams Rite MS1890 rated for commercial use in a school or hospital?
It carries a Grade 1 rating and is a commercial lock, the top ANSI/BHMA durability tier for commercial door hardware. That's what facilities standardizing across a campus normally spec. It's used in banking, retail, office, warehouse, education, healthcare, and government buildings. If you're standardizing, note that the same lock body covers three backsets and three anodized finishes, so one part family can cover a mixed set of storefront openings.
14) How much room does the MS+1890 need inside the stile?
The case measures 1 x 7-3/8 inches by depth, so you need a mortise pocket that takes a 1 inch wide, 7-3/8 inch long case, and the depth is set by the backset you order: 31/32, 1-1/8, or 1-1/2 inch. On a retrofit, that 7-3/8 inch length is the number to check first against the existing pocket, since a shorter prep means cutting the stile rather than dropping the lock in.
15) Where do I get the install template and prep dimensions for the Adams Rite MS+1890?
Adams Rite publishes installation instructions and a product directory for the MS+1890 Series, and the manufacturer's templates are what you mark the door and frame from. Prep sequence is: mortise the stile for the 1 x 7-3/8 inch case, drill the cylinder hole at your ordered backset, set the case, then install the armored strike aligned to both the hookbolt and the latchbolt before testing operation.
