Frequently asked questions

What does an Adams Rite MS1850S deadlock cost?

The current book price is on this page, resolved live from the Adams Rite price book. Faceplate, backset, bolt shape, handing and finish complete the MS1850S part number; a bare MS1850S already carries the flat faceplate (0S) and non-handed (0) codes, so the picker above asks for the backset, bolt shape and finish.

How secure is the MS1850S bolt?

The bolt is eight-ply laminated stainless steel, and Adams Rite states its center ply has an alumina-ceramic core to defeat any hacksaw attack, including rod-type "super" hacksaws.

Should I pick the straight bolt or the hookbolt?

The MS1850S orders with bolt shape 1 (standard straight bolt, 5/8" x 1-3/8" x 2-7/8" with a 1-3/8" throw) or bolt shape 5 (hookbolt, 13/16" throw). Adams Rite notes the hook-shaped bolt repels pry bar attempts to "spread" the door from its jamb or lift it off its track.

What backsets does the MS1850S come in?

Under the heading Backset the spec sheet prints 7/8", 31/32", 1-1/8" and 1-1/2", with case depth varying by backset.

What cylinder or thumbturn works with the MS1850S?

Any standard 1" length, 1-5/32" diameter mortise cylinder with an MS cam — such as the 4036 Mortise Cylinder — or a 4066 Thumbturn, available separately. The lock accepts a cylinder from either or both sides.

Is the MS1850S handed?

The MS1850S ordering chart prints "Non-Handed*" (code 0) alongside handed codes 5 (LH or RHR) and 6 (RH or LHR). Adams Rite reserves the handed codes for the bevel faceplate (2S), which requires 5 or 6 and does not allow non-handed; the flat, radius and without-faceplate models are non-handed and use 0.
