Adams Rite 28-0064-03-MP – Frequently Asked Questions

1) Which Adams Rite lock does the 28-0064-03-MP spring fit?
The 28-0064-03-MP is a genuine Adams Rite replacement spring made for the MS1850S Series MS Deadlock, and only for that series. It drops into the existing deadlock assembly without modification, so there is no need to pull and replace the whole lock body to restore spring-driven operation.
2) My storefront deadlock won't throw smoothly anymore. Is a spring the part I need?
If the lock is an Adams Rite MS1850S Series MS Deadlock and the bolt action has gone sluggish or the mechanism isn't returning properly, the 28-0064-03-MP spring is the service part for it. It restores the spring-driven action inside the deadlock assembly so the lock operates as originally built, which is the usual field repair on a storefront aluminum door before condemning the lock.
3) Can a Corbin Russwin swivel spindle pin be used in place of the Adams Rite 28-0064-03-MP spring on an MS1850S deadlock?
No. The Adams Rite 28-0064-03-MP is a replacement spring made specifically for the MS1850S Series MS Deadlock and drops into that assembly without modification. The Corbin Russwin Swivel Spindle Pin X Set Screw is a spindle pin and set screw for a knob or lever trim assembly on a 1-3/4 inch door, so it performs a different mechanical job entirely and will not restore spring action in an MS Deadlock. If the deadlock's spring has failed, the 28-0064-03-MP is the part that addresses it.
4) Is the Adams Rite 28-0064-03-MP an OEM part or an aftermarket copy?
It is genuine Adams Rite, built to the original specification for the MS1850S Series. For facilities that standardize on Adams Rite hardware, that matters: an OEM spring keeps the serviced lock inside its original installation specification rather than introducing an unknown part into the assembly.
5) Will the Adams Rite 28-0064-03-MP work in a Corbin Russwin lock?
No. This spring is made exclusively for the Adams Rite MS1850S Series MS Deadlock and should not be substituted into another manufacturer's lock. For Corbin Russwin work, the corresponding small parts are that brand's own, for example the Corbin Russwin Swivel Spindle Pin X Set Screw, which is listed for 1-3/4 inch doors.
6) Do I have to order anything else with the 28-0064-03-MP to repair an MS1850S deadlock?
The 28-0064-03-MP is sold as a single replacement spring in one configuration, with no finish, handing, or size choices to specify. If the repair also involves worn cylinder or spindle components, those are ordered separately as their own Adams Rite part numbers.
7) Is this Adams Rite spring rated for commercial door use or is it a residential part?
Commercial. The 28-0064-03-MP is catalogued as a commercial door hardware component, which is consistent with where MS1850S deadlocks live: office entries, retail storefronts, schools, healthcare, warehouses, and government buildings under an MRO service program.
