Adams Rite P170-05-14-MP – Frequently Asked Questions

1) What is the Adams Rite P170-05-14-MP roll pin used for?
The P170-05-14-MP is the roll pin inside the 4015 Threshold Bolt assembly used with the Adams Rite MS1850 Series MS Deadlock. It is a factory replacement pin, so it goes back into the same hole in the threshold bolt without drilling or modifying the existing assembly.
2) Will this Adams Rite roll pin fit an MS1850 deadlock other than the 4015 threshold bolt setup?
No. The P170-05-14-MP is made specifically for the 4015 Threshold Bolt mechanism within the MS1850 Series. If you are chasing a worn pin, spring or cam somewhere else in an MS deadlock, you need the part called out for that assembly, not this one.
3) Can a Kwikset 84290 or 83521 plain latch be used in place of the Adams Rite P170-05-14-MP?
No. The P170-05-14-MP is a roll pin, an internal component of the 4015 Threshold Bolt within the MS1850 Series MS Deadlock assembly, and it is sold as a replacement part rather than a complete latch. The Kwikset 84290 is a square corner plain latch with a 2-3/8 inch backset and the Kwikset 83521 is an RCAL plain latch for BBL, KNL, CNL and PLL trim - both are bored-door latch units that install in a cross-bore and edge bore. Nothing about a bored latch serves the MS1850 threshold bolt mechanism, so if the threshold bolt is what needs service, the Adams Rite pin is the part that addresses it.
4) I need a latch for a wood door with a 2-3/8 or 2-3/4 inch backset, not an Adams Rite part - what should I look at?
The Adams Rite P170-05-14-MP is a commercial replacement roll pin for the MS1850 Series lock and has no backset of its own, so it will not serve a bored wood door. For an adjustable-backset drive-in latch at 2-3/8 or 2-3/4 inches, the Deltana DLP23875 covers passage and privacy functions and the Deltana DLE23875 covers entry function; both list a door thickness range of 1-3/8 inch to 2 inch. Choose between them by whether the opening needs a keyed or non-keyed trim.
5) Can I rebuild a worn threshold bolt instead of buying a whole new MS1850 lock?
That is exactly what this pin is for. Replacing the roll pin in the 4015 Threshold Bolt lets you restore engagement in the bolt assembly and keep the existing MS1850 lock in service rather than pulling and replacing the complete unit. It is catalogued by Adams Rite as a replacement part for that purpose.
6) Is an aftermarket pin acceptable in an Adams Rite MS1850 threshold bolt?
Use the OEM pin. The P170-05-14-MP is made to Adams Rite factory dimensional tolerances so the threshold bolt reassembles and operates as built. A generic roll pin that is off on diameter or length can walk out or bind the bolt, and on a threshold bolt that means the door is either not securing at the floor or not retracting.
7) Is the Adams Rite P170-05-14-MP the same thing as a drive-in latch or a plain latch?
No, and it is an easy mix-up when searching. This is an internal roll pin for a threshold bolt, not a latch unit. Products like the Deltana DLE23875 drive-in entry latch or the Kwikset 84290 square corner plainlatch with a 2-3/8 inch backset are complete bored-door latches and will not serve as a repair part inside an MS1850 deadlock.
8) Is the P170-05-14-MP a deadbolt part I can use on an electrified opening?
The P170-05-14-MP is a mechanical component - a roll pin inside the 4015 Threshold Bolt of the MS1850 Series MS Deadlock - and carries no electrical function. For a motorized deadbolt latch, the Emtek LC9-DBLTCH in the EMPowered series is built as a deadbolt latch with motorized operation. The two address different systems entirely: the Adams Rite pin restores an existing mechanical MS1850 lock, while the Emtek unit is part of an access-control deadbolt.
9) Is the Adams Rite P170-05-14-MP a commercial-duty part or residential?
Commercial. The MS1850 Series deadlock it belongs to is commercial door hardware, typically found on aluminum storefront and institutional openings - offices, retail, schools, healthcare, government and industrial buildings. A property manager standardizing on MS deadlocks across a portfolio would keep this pin as a stocked spare.
10) What is the difference between ordering the Adams Rite P170-05-14-MP and ordering a faceplate and screw kit like the Emtek 83228?
Both are service parts rather than complete locks, but they replace different things. The P170-05-14-MP is the roll pin inside the 4015 Threshold Bolt of an MS1850 Series MS Deadlock, an internal component that keeps the mechanism engaging properly. The Emtek 83228 is a faceplate and screws with square corners for a tubular pocket door privacy latch, which is exterior trim hardware for a privacy, bed or bath function. If the MS1850 threshold bolt is binding, the pin is the item; a faceplate kit will not reach that mechanism.
