Schlage 20-090 626 – Frequently Asked Questions

1) Will the Schlage 20-090 mortise cylinder housing work in an Adams Rite 4070 deadlock?
That is exactly what the cam is cut for. The 20-090 housing carries the AR 4070 cam, cam number B520-378, and is listed as compatible with Adams Rite 4070 deadlocks. Cam profile is the spec that decides whether a mortise cylinder actually throws the bolt, so a housing with any other cam can thread into the lock body and still do nothing. Get the cam right and the rest is finish and length.
2) Does the Schlage 20-090 come with a core and keys, or is that ordered separately?
20-090 is the housing and shell only. It is the body that mounts in the lock and carries the AR 4070 cam; the interchangeable core that holds the pinning and the keyway is a separate component, so you add the core that matches the key system the building already runs. That split is the whole point of Schlage's modular cylinder approach: hold housings in the cams and lengths you need, then drop in whichever core the job calls for.
3) The cylinder on our storefront deadlock is worn out. How do I know if the Schlage 20-090 is the right replacement?
Pull the old cylinder and identify the lock body first. If it is an Adams Rite 4070, the 20-090 is the match: a commercial mortise cylinder housing sold as a replacement part with the AR 4070 cam, cam number B520-378. The 4070 is Adams Rite's deadlock for narrow stile aluminum entrance doors, so it is the one you find on most glass front openings. If the lock body turns out to be an MS1847 or a 5017 wood door deadlock, the 4070 cam is the wrong profile and you need a different cylinder.
4) Can a Schlage 20-090 cylinder housing be keyed into the master key system we already run?
Keying lives in the core, not the housing, and Schlage's modular cylinder supports interchangeability between Everest 29, Primus XP and Classic key systems. So a 4070 deadlock on an entrance can sit on the same key system as the mortise and cylindrical locks elsewhere in the building, which is the point for anyone trying to keep one key ring per property rather than one per door type.
5) My doors are thicker than standard. Do I need a different Schlage modular cylinder housing?
Door thickness is handled by the rear housing on the Schlage modular cylinder, which is offered in six lengths to accommodate thicker doors. The cam and the front housing stay the same; you step the rear housing up to suit. Measure the door and the existing cylinder before you order rather than assuming the standard length reaches the cam.
6) We have Adams Rite 4070 deadlocks on several entrances. Can we standardize on one replacement cylinder housing across all of them?
One part number covers the lot. The 20-090 is non-handed, so left hand and right hand openings take the same housing, and the AR 4070 cam suits every 4070 deadlock in the building. Body is stainless steel. The only things that vary door to door are finish and, if some doors are thicker, rear housing length. That makes it a sensible shelf item for a facility running the same deadlock across multiple entrances.
7) Can a Schlage modular cylinder be converted from mortise to rim or key-in-lever?
Changing the tailpiece, cam or rear housing does it. One modular cylinder converts to three cylinder types, which is how a service van stays stocked without carrying a separate cylinder for every lock on the route. The 20-090 is the mortise configuration with the AR 4070 cam on it; the same cylinder body serves rim or key-in-lever and key-in-knob applications once the cam or tailpiece is swapped.
8) I need the cylinder face on my Adams Rite deadlock to match the rest of the door hardware. What finish options are there on the Schlage 20-090?
Eleven finishes, covering both the commercial matches and the decorative ones: 626 Satin Chrome, 625 Bright Chrome, 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 612 Satin Bronze, 613 Oil Rubbed Bronze, 643E Aged Bronze, 619 Satin Nickel, 622 Matte Black, and 626AM Satin Chrome Antimicrobial. 626 is the finish that lines up with most commercial lock and exit hardware, so it is the default on a back-of-house or service entrance. 626AM is the one to specify where a healthcare facility is standardizing on antimicrobial hardware.
9) We have Schlage L9000 mortise locks in the same building as the deadlocks. Will one cylinder cover both?
Not with the same cam. The Schlage 20-090 is set up for Adams Rite 4070 deadlocks and carries the AR 4070 cam, part number B520-378. For the L9000 mortise locks, the Corbin Russwin CR1080-112-A01 is the part written for them: a 1080 Grade 1 series 1-1/2" LFIC mortise cylinder, 6-pin, called out for Schlage L9000 mortise locks with an A01 Schlage L cam. Standardizing a building with both lock types means planning for two different cams, one per lock body.
10) Our facility spec calls out Grade 1 cylinders. Which mortise cylinders in the Adams Rite and Corbin Russwin lines carry that rating?
The Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security, for doors of 1/2" minimum thickness. On the Corbin Russwin side, the CR1000-112 is a 1000 Grade 1 series mortise cylinder, 1-1/2", with an A02 straight cam; the CR1070-114-A01 is a 1070 Grade 1 series 1-1/4" 6-pin mortise housing with an A01 cloverleaf cam; and the CR1080-112-A01 is a 1080 Grade 1 series 1-1/2" LFIC mortise cylinder, 6-pin, with an A01 Schlage L cam. Those three carry different cams, so pair each one to its lock body rather than to the rating alone. The Schlage 20-090 is a commercial mortise housing in stainless steel carrying the AR 4070 cam for Adams Rite 4070 deadlocks.
11) Can I use an Adams Rite 4024 or 4025 cylinder pull where a mortise housing is called for?
They are not interchangeable. The Adams Rite 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws, and both are made for the Adams Rite MS1847 deadlock and deadlatch. The 4026 is a five pin tumbler cylinder pull for wood door applications, built for the Adams Rite 5017 wood door deadlock and deadlatch. All three are pull assemblies matched to a different Adams Rite lock. The Schlage 20-090 is a mortise housing whose compatibility is the Adams Rite 4070 deadlock, so if the 4070 is what is in the door, the pulls are the wrong family entirely.
12) I need a mortise housing for an Adams Rite 4070 deadlock. Is the Corbin Russwin 1070 housing the same part?
No, and the cam is the reason. The Schlage 20-090 is a mortise housing supplied with an AR 4070 cam, cam number B520-378, and its stated compatibility is Adams Rite 4070 deadlocks. The Corbin Russwin CR1070-114-A01 is a 1-1/4" 6-pin mortise housing carrying an A01 cloverleaf cam. Both are mortise housings built to take a core, but the cam is the piece that turns the lock body, so it has to be the cam the deadlock in the door is built to accept. Settle the cam first, then the finish.
13) Does it have to be a housing plus a core, or is there a one piece mortise cylinder I can set in the door instead?
Both routes exist in mortise. The Schlage 20-090 is the housing, or shell, that accepts an interchangeable core, so the keying arrives as its own part. If you would rather install one finished cylinder, the Corbin Russwin CR1000-112 is a 1000 Grade 1 series mortise cylinder, 1-1/2" length, with an A02 straight cam, and the Detex MC65 is a 1-1/8" 6-pin mortise cylinder cut to the Schlage C keyway. Check the cam against the lock body before you commit either way: the Schlage 20-090 carries the AR 4070 cam for Adams Rite 4070 deadlocks, while the CR1000-112 carries an A02 straight cam.
14) What is the difference between the Schlage 20-090 and the Adams Rite 4036 mortise cylinder?
One is a shell, the other is a finished cylinder. The Schlage 20-090 is a stainless steel mortise housing, non-handed, carrying an AR 4070 cam, cam number B520-378, for Adams Rite 4070 deadlocks; the core and the keying come as separate parts you build into it. The Adams Rite 4036 is a mortise cylinder with five-pin security from the 4036 series, rated Grade 1, and it works on doors of 1/2" minimum thickness. So the decision is whether you want a cylinder you can re-core later or one that ships complete.
15) Rim housing or mortise housing - how do I tell which one the opening actually needs?
The drive component tells you. The Schlage 20-090 is a mortise part: its lock type is mortise and it turns the lock through a cam, the AR 4070, cam number B520-378. A rim part drives through a tailpiece instead, the way the Corbin Russwin 3070-178 does, a 3000 series 6-pin rim cylinder housing with a 1-7/8" tailpiece. The Schlage modular cylinder is built so one cylinder can be taken to mortise, rim, or key-in-lever by changing the tailpiece, cam, or rear housing, which is exactly the point: the body can be common, the drive component is what the door decides.
16) A supplier sent me BEST 1C core numbers as a swap for the Schlage 20-090. Is that the same item?
Those are a different piece of the assembly. The BEST 1C5 is a standard 5-pin cylinder core, the 1CB is a Peaks 150 series interchangeable core cylinder, and the 1CDF is a drill resistant patented interchangeable core in 7-pin brass, also 150 series. A core is the part that carries the pinning and the keyway. The Schlage 20-090 is the stainless steel mortise housing that holds a core and carries the AR 4070 cam for Adams Rite 4070 deadlocks. A core brings no cam with it and a housing brings no keying, so one never stands in for the other - they are two lines on the same order.
17) If the deadlocks take the Schlage 20-090, what cylinder goes into the lever locks?
A lever takes a key-in-lever cylinder, not a mortise housing. The Schlage 20-090 is a mortise housing carrying the AR 4070 cam. For the levers, the Falcon A23161-05 G is a key in lever cylinder, RU/T series 6-pin G keyway, keyed different and supplied with 2 cut keys, and the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder. The Schlage modular cylinder is designed to be taken from mortise to rim to key-in-lever or key-in-knob by changing the tailpiece, cam, or rear housing, so the question on each opening is which drive component the lock is built around.
18) Can a Medeco 1075127 or 1012040 cylinder go in place of a mortise housing on an Adams Rite deadlock?
No, those are rim cylinders aimed at deadbolts and handlesets. 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, and the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece. Each drives its lock through a tailpiece. The Schlage 20-090 is a commercial mortise housing that drives through the AR 4070 cam, number B520-378, and its compatibility is Adams Rite 4070 deadlocks, so the mounting and the drive are both different.
