  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and frame surfaces, ensuring proper alignment with sliding door track system.
  3. Prepare door and frame by drilling required holes and routing as specified in manufacturer instructions, taking care to maintain structural integrity of narrow stile construction.
  4. Install all mounting hardware and secure the deadlock to door and frame per manufacturer torque specifications, ensuring proper clearance for sliding operation.
  5. Install mortise cylinder or thumbturn components and verify 360-degree key operation for bolt projection and retraction with counterbalanced mechanism.
  6. Test deadlock operation to verify proper hookbolt engagement with strike, smooth sliding door movement, and positive locking in both extended and retracted positions. Refer to manufacturer documentation for complete installation details and troubleshooting.

Maximum Security Design

The MS1950-X5X Series represents the pinnacle of sliding door security with its massive laminated stainless steel hookbolt construction. The eight-ply laminated design with alumina-ceramic core provides unmatched resistance to cutting attacks, while the hook shape specifically counters the parting motion typical of sliding door break-in attempts. The over-center MS locking action creates positive engagement that becomes stronger under attack, making this deadlock ideal for high-security applications where maximum protection is essential.

Adams Rite MS1950-355-628 – Frequently Asked Questions

1) Will the Adams Rite MS1950 hookbolt deadlock work on my narrow stile aluminum sliding door?
That's exactly what the MS1950 is built for. It's a hookbolt deadlock for sliding narrow stile aluminum doors, and the case is 1 inch wide, which is what lets it fit inside a narrow stile. Hollow metal and wood door options are also available. Pick the backset to match your stile: 31/32 inch, 1-1/8 inch, or 1-1/2 inch.
2) Why use a hookbolt instead of a straight deadbolt on a sliding door?
A sliding door fails by parting, not by being pushed in, so a straight bolt can be jimmied out of the strike as the leaf slides. The MS1950's hook shape swings out and catches behind the strike, countering that parting motion, and the over-center MS locking action pulls tighter under load rather than backing off. On a swinging door a straight deadbolt is fine. On a slider, the hook is the reason to buy this lock.
3) How far does the MS1950 hookbolt throw, and will it reach my strike?
The hookbolt is 5/8 inch by 1-3/8 inch with a 13/16 inch throw. Set your strike so the hook clears and rotates fully behind the keeper at that 13/16 inch projection, measured from the faceplate. The lock is specified with an armored strike, which is what you want on a maximum security opening: a plain formed keeper is the weak link when the bolt itself is laminated stainless.
4) Does the Adams Rite MS1950 deadlock come with a cylinder?
No cylinder ships with it. The MS1950 accepts standard Adams Rite MS cam mortise cylinders, so you order the cylinder separately and key it into your system. That's normal for this lock and it's what lets a locksmith key the opening to an existing keyway rather than living with a factory key.
5) Do I have to specify handing when ordering an MS1950 hookbolt deadlock?
Handing matters here, because a hookbolt swings toward one side. The MS1950 is ordered as LH or RHR, RH or LHR, or non-handed depending on the configuration. Stand outside the opening and note which way the active leaf slides before you order; a handed lock on the wrong hand will not catch the strike.
6) What do I need to order besides the MS1950 deadlock to finish the job?
Three things beyond the lock itself. An Adams Rite MS cam mortise cylinder, since none is included. An armored strike for the jamb or the mating leaf. And, if the opening is going on access control, an Adams Rite electric strike. Faceplate profile and backset are chosen on the lock order, not bought separately.
7) What faceplate should I order with the MS1950 deadlock?
Five faceplate choices: flat, bevel, radius, radius with weatherstrip, and a no-faceplate version. Match the profile to the stile you're cutting into. Radius with weatherstrip is the one to take on an exterior slider where the stile carries a weatherstrip pocket, and the without-faceplate option is for a prep where the existing plate stays.
8) Is the Adams Rite MS1950 hookbolt deadlock rated for high traffic commercial or institutional use?
It's a Grade 1 commercial deadlock, the highest ANSI/BHMA durability tier, and it's a commercial product rather than a residential one. For a facility standardizing on one lock across sliding entrances, warehouse perimeter doors, or secure storage, Grade 1 is the specification most institutional buyers are required to hit.
9) Can the MS1950 hookbolt resist being cut with a hacksaw?
The hookbolt is an eight-ply laminated stainless steel build with an alumina-ceramic core, and that core is what stops a blade, including rod-type super hacksaws. The case is fully stainless as well. This is the reason to choose the MS1950 over a lighter hookbolt on an opening that gets attacked rather than just locked.
10) Can I put an MS1950 deadlock on an access control system?
Yes, the MS1950 works with Adams Rite electric strikes, so the opening can be released from a card reader or a door station while the hookbolt still throws mechanically for after-hours lockdown. UL Listed models are available within the series if your opening requires one. Pair the lock with an armored strike prep so the electric strike lands in a reinforced pocket.
11) How much of the stile does the MS1950 lock case take up?
The case measures 1 x 6 inches by depth, so you're routing a 6 inch long pocket into the stile. Check that against the stile height available between the rail and any glazing pocket before you cut, and choose the backset (31/32, 1-1/8, or 1-1/2 inch) that puts the cylinder centered on the stile face.
12) What finishes does the Adams Rite MS1950 come in for matching other doors in a building?
Three anodized finishes: 628 clear anodized, 313 dark bronze anodized, and 335 black anodized. Those are the standard aluminum storefront finishes, so a clear anodized MS1950 sits with untinted aluminum framing and 313 matches the dark bronze framing you see on most older commercial entrances. Spec one finish across a property and the openings read consistently.
