Adams Rite 28-0064-02-MP – Frequently Asked Questions

1) My MS1850S deadbolt is sluggish and won't return properly, is the spring the part I need?
That is exactly what the 28-0064-02-MP addresses. It restores the spring-action return in the MS1850S deadlock mechanism, which is the component responsible for the mechanism coming back to its correct operating position. If the bolt itself is bent or the cylinder is failing, the spring won't fix that, but a mechanism that turns but doesn't return crisply is a spring job.
2) Is the 28-0064-02-MP a genuine Adams Rite part or an aftermarket spring?
Genuine OEM. It is supplied through the Adams Rite parts and accessories line, manufactured to the same specification as the spring originally fitted in the MS1850S deadlock. For locksmiths rebuilding a lock rather than replacing it, that matters: an aftermarket spring with a different rate changes the feel and the return of the mechanism.
3) Do I need anything else to rebuild the deadlock, or is the spring all that is ordered here?
What ships is the spring alone, a single part under model 28-0064-02-MP with no size or finish choices to specify. No cylinder, no bolt, no strike and no screws come with it. Plan the service call on the assumption you are opening the existing MS1850S case and swapping the one component.
4) Can a Corbin Russwin swivel spindle pin and set screw be used in place of the Adams Rite 28-0064-02-MP spring?
No. The Adams Rite 28-0064-02-MP is a replacement spring made specifically for the MS1850S Series MS Deadlock, restoring the spring-action operation of that deadlock mechanism. The Corbin Russwin Swivel Spindle Pin X Set Screw is a spindle pin and set screw, a knob or lever spindle retention part, and it is listed for 1-3/4 inch doors. The two serve different mechanisms, so one is not a stand-in for the other even though both are small internal lock parts.
5) Is this Adams Rite spring rated for commercial door use?
Yes, it is a commercial-grade part. Adams Rite classes the 28-0064-02-MP as commercial rather than residential, which is consistent with where MS1850S deadlocks get installed: retail storefronts, office buildings, schools, healthcare, government and multi-tenant properties. For an MRO stockroom running aluminum storefront entrances, it is a sensible spare to keep on the shelf.
