Adams Rite 4066-01-335 – Frequently Asked Questions

1) Which version of the Adams Rite 4066 thumbturn do I order for my lock?
The 4066 thumbturn is built in three lock-specific versions: one for MS locks and deadlatches, one for the 4070 deadlock, and one for the 2331 deadlock. Identify the lock already in the door and order the version that names it rather than assuming one part covers all three, since the cam configuration has to suit the lock it drives. Each of the three is offered in aluminum, dark bronze anodized, and black anodized.
2) What keyed cylinder do I use on the outside of the door with an Adams Rite 4066 thumbturn?
Look for a mortise cylinder in the same envelope the thumbturn occupies, 1 inch length and 1-5/32 inch diameter, with the Adams Rite MS cam. Length is the thing that decides it. Common Grade 1 mortise cylinders run longer than that: the Corbin Russwin 1000 Series is listed at 1-1/2 inch, the Corbin Russwin 1070 housing at 1-1/4 inch, and the Detex MC65 at 1-1/8 inch. A cylinder longer than the prep will not seat correctly in a narrow stile lock, so the length spec and the MS cam are what to check first, not the keyway.
3) Tenants keep getting locked in behind the storefront deadlock. Can I put a thumbturn on the inside instead of a second key cylinder?
That is exactly the swap the 4066 makes. It drops into the inside cylinder position on Adams Rite MS locks and deadlatches, the 4070 deadlock, or the 2331 deadlock, replacing a standard 1 inch mortise cylinder with a turn lever so nobody inside needs a key to throw or retract the bolt. Order the version that matches which of those three locks is in the door.
4) Can a Schlage 20-021 or 20-022 rim cylinder be used in place of an Adams Rite 4066 thumbturn?
No. The Adams Rite 4066 non-keyed thumbturn interchanges with standard 1 inch [25.4 mm] length, 1-5/32 inch [29.4 mm] diameter mortise cylinders and accepts standard Adams Rite MS cam mortise cylinders in deadlocks and deadlatches. The Schlage Commercial 20-021 and 20-022 are 6-pin rim cylinders, the 20-021 with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam, and the Corbin Russwin 3070-178 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Rim cylinders mount through the door face and drive a rim device with a flat tailpiece, so they belong on rim exit hardware, not in a mortise cylinder prep. A narrow stile mortise deadlock takes either a mortise-format cylinder or the 4066 thumbturn in that hole.
5) The 4066 thumbturn covers the inside of an MS deadlock. What cylinder goes on the outside when the door has to be keyed?
The Adams Rite 4066 is non-keyed, so it handles the inside turn only and a keyed opening needs a mortise cylinder on the outside carrying the cam the lock body calls for. The 4066 itself replaces a standard 1 inch [25.4 mm] length, 1-5/32 inch [29.4 mm] diameter mortise cylinder and accepts standard Adams Rite MS cam mortise cylinders. Among keyed mortise cylinders, the Corbin Russwin CR1000-112 is a Grade 1 1000 series cylinder 1-1/2 inches long with an A02 straight cam, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder cut to the Schlage C keyway. Both run longer than the 1 inch length the 4066 interchanges at and both carry a cam of their own, so confirm cam form and cylinder length against the deadlock body and the door thickness before ordering.
6) Is the Adams Rite 4066 thumbturn only for aluminum storefront doors?
Narrow stile aluminum is what it was built around, and that is where most of them go, but hollow metal and wood door options are offered too. What actually governs the fit is the lock and the cylinder prep, not the door material: the door has to carry an Adams Rite MS lock or deadlatch, a 4070 deadlock, or a 2331 deadlock, with a 1 inch mortise cylinder hole.
7) I need to match dark bronze storefront hardware across a building. Does the Adams Rite 4066 come in bronze for every lock type?
All three finishes cover all three lock versions. Aluminum (130), dark bronze anodized (313), and black anodized (335) are each offered for MS locks and deadlatches, for the 4070 deadlock, and for the 2331 deadlock, which is nine combinations. So a building standardized on dark bronze can carry the same finish across doors running different Adams Rite locks.
8) Is a dummy cylinder the same thing as a non-keyed thumbturn?
No, and the difference decides whether the door works. The BEST 12E series dummy rim cylinder is a 1-5/32 inch diameter rim cylinder that closes off a cylinder hole and operates nothing. The Adams Rite 4066 is a working non-keyed thumbturn that takes the mortise cylinder position in Adams Rite deadlocks and deadlatches, interchanging with a standard 1 inch [25.4 mm] length, 1-5/32 inch [29.4 mm] diameter mortise cylinder, and it operates the lock from the inside without a key. Specify a dummy where a hole simply needs to be filled and the 4066 where the inside face has to lock and unlock the door.
9) We are standardizing a building on interchangeable cores. Does the thumbturn side of an MS deadlock take a core?
No. The Adams Rite 4066 is non-keyed, so it sits outside the keying schedule entirely, with no core and nothing to rekey on that side. Interchangeable core products belong on the keyed side of the opening: the BEST 1C standard 5-pin cylinder core, the BEST Peaks 1CB 150 series interchangeable core cylinder, the BEST 1CDF drill resistant patented 7-pin brass 150 series core, and in rim format the Schlage Commercial 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam or the 20-057-C full size interchangeable core in the C keyway, 643E aged bronze. Spec the core against the outside cylinder and count the 4066 thumbturn openings separately, since they consume no cores.
10) Will a Corbin Russwin 1080 or 1070 mortise cylinder drop into an Adams Rite MS deadlock where the 4066 goes?
Those two are built around cams for other lock families. The Corbin Russwin CR1080-112-A01 is a 1-1/2 inch LFIC 6-pin mortise cylinder specified for Schlage L9000 mortise locks with an A01 Schlage L cam, and the CR1070-114-A01 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. The Adams Rite 4066 replaces a standard 1 inch [25.4 mm] length, 1-5/32 inch [29.4 mm] diameter mortise cylinder and accepts standard Adams Rite MS cam mortise cylinders, and it is ordered against the specific lock it serves, whether that is MS locks and deadlatches, the 4070 deadlock, or the 2331 deadlock. On a narrow stile deadlock the cam form and the cylinder length govern fit, not the mortise thread alone.
11) Can I use an Adams Rite 4066 thumbturn on a door that is on access control?
Yes, it works alongside Adams Rite electric strikes on access-controlled openings. The thumbturn handles mechanical operation of the deadlock or deadlatch from the inside while the strike handles released entry from the credential side, so the two sit on the same door without conflicting.
12) Can a key-in-knob or key-in-lever replacement cylinder be used where the Adams Rite 4066 goes?
No. The Kaba Ilco 1539 key-in-knob and lever universal cylinder, the 1579 knob and lever cylinder for Sargent, the 1599 key-in-knob replacement cylinder, the 1549 key-in-deadbolt cylinder, and the Falcon A23161-05 G key in lever cylinder in the RU/T series 6-pin G keyway are replacement cylinders for the cylindrical bodies of knobs, levers and bored deadbolts. The Adams Rite 4066 non-keyed thumbturn occupies the mortise cylinder position of an Adams Rite deadlock or deadlatch in a narrow stile aluminum door, interchanging with a standard 1 inch [25.4 mm] length, 1-5/32 inch [29.4 mm] diameter mortise cylinder. A knob or lever cylinder carries no mortise thread and no MS cam, so the two formats serve different lock bodies.
13) Do Medeco or Emtek deadbolt and handleset cylinders cross over to an Adams Rite MS deadlock?
They are built for different lock bodies. The Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and the Emtek handleset and deadbolt outside cylinder, and the Emtek CY4 is an Emtek cylinder sold individually. Each of those drives a bolt through a tailpiece behind a bored deadbolt or handleset. The Adams Rite 4066 is a non-keyed thumbturn that takes the mortise cylinder position in an Adams Rite deadlock or deadlatch on a narrow stile aluminum door and needs no key on that side at all.
