BEST 1E64-C161RP2626 – Frequently Asked Questions

1) Does the BEST 1E mortise cylinder come with a core, or do I have to order one separately?
It ships less core. The 1E Series mortise cylinder is 6-pin SFIC prepped, meaning the housing is machined to accept a BEST small format interchangeable core, but the core itself is a separate order. Plan on a 6-pin SFIC core in your keyway, plus the control key to install it. That is the point of the SFIC prep: once the housing is in the lock, cores swap out with the control key without pulling the cylinder.
2) What cam is on this BEST 1E cylinder and what locks will it drive?
C161 clover cam. That cam profile is set up for Arrow and Corbin Russwin deadbolt mechanisms, so the housing turns those bolts correctly. If your lock takes a straight cam or a different profile, this is the wrong cylinder as shipped, though the 1E housing can be refitted with other cams and rings to suit other makers' locks.
3) I need a straight cam mortise cylinder instead of a clover cam - what should I order?
The BEST 1E Series carries a C161 clover cam, which is the profile the Arrow and Corbin Russwin deadbolts it is intended for expect. When the lock case calls for a straight cam instead, the Corbin Russwin 1000 Grade 1 mortise cylinder is a 1-1/2 inch length with an A02 straight cam. Confirm the cam profile against the lock case before ordering, since cam shape and cylinder length both have to match the housing.
4) Is a rim cylinder a substitute for the BEST 1E mortise cylinder?
No. The BEST 1E is a threaded mortise cylinder with a C161 clover cam that screws into a mortise lock body. Rim cylinders mount through the door behind a surface-applied rim device and drive it with a tailpiece, not a cam - the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, the 20-022 is the same with a horizontal tailpiece, and the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. They are not interchangeable with a mortise prep.
5) What is the closest equivalent to the BEST 1E mortise cylinder if I need a cloverleaf cam but in a longer body?
The BEST 1E Series mortise cylinder is a 1-1/8 inch body with a C161 clover cam and 6-pin SFIC prep less core. If the mortise lock case needs more cylinder length, the Corbin Russwin 1070 Grade 1 mortise housing is a 1-1/4 inch 6-pin housing with an A01 cloverleaft cam, and the Corbin Russwin 1080 is a 1-1/2 inch 6-pin LFIC mortise cylinder with an A01 cloverleaf cam for Schlage L9000 mortise locks. Note the core format differs: the BEST 1E takes a small format interchangeable core, while the 1080 is built around a large format interchangeable core.
6) I want a 1-1/8 inch mortise cylinder that comes keyed rather than less core - what are my options?
The BEST 1E Series is supplied with 6-pin SFIC prep less core, so the core and keys are ordered separately and dropped in - that is what makes it work inside an existing BEST master key system. If you want a conventional 1-1/8 inch mortise cylinder that is keyed as a unit, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway. The tradeoff is rekeying: the MC65 is pinned as a conventional cylinder, while the 1E lets you swap cores without pulling the cylinder from the lock.
7) Will the BEST 1E work on an Adams Rite narrow stile deadlock, or do I need something else?
The BEST 1E is a 1-1/8 inch mortise cylinder cammed for Arrow and Corbin Russwin deadbolts. Aluminum narrow stile deadlocks take purpose-built hardware instead: the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness, and for cylinder pull applications the 4024 and 4025 are made for the MS1847 deadlock and deadlatch, while the 4026 suits the 5017 wood door deadlock. Match the cylinder to the deadlock model rather than to the door.
8) Can I add this cylinder to an existing BEST master key system?
Yes, as long as the core you fit is on that system. The housing is BEST SFIC prepped, so any 6-pin BEST small format core keyed into your existing master system drops straight in. The housing itself is uncoded, all the keying lives in the core.
9) Is a small format interchangeable core cylinder the right choice, or should I use a conventional keyed cylinder?
Go SFIC when you rekey often or manage many doors, tenant turnover, staff changes, a campus. Cores pull with a control key in seconds and nobody has to take a lock apart. Go conventional keyed when it is one or two doors and you want the cylinder to arrive keyed with cut keys in the box, the way the Detex MC65 mortise cylinder does in Schlage C keyway at 1-1/8 inch. If your system is standardized on full size interchangeable core instead of small format, a BEST SFIC housing will not take your cores; Schlage's 20-057 6-pin FSIC rim cylinder is the FSIC style, and note that is a rim cylinder, not a mortise one.
10) My opening is a key-in-knob or key-in-lever lock, not a mortise case. What cylinder do I use?
The BEST 1E is a mortise cylinder and threads into a mortise lock body - it will not fit a knob or lever chassis. For those, the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, the 1579 is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder. For a keyed deadbolt chassis the Ilco 1549 key-in-deadbolt cylinder is the corresponding part. In a lever with a G keyway, the Falcon A23161-05 G is a 6-pin key-in-lever cylinder supplied keyed different with two cut keys.
11) What is the difference between the BEST 1E small format core and a full size interchangeable core cylinder?
The BEST 1E is prepped for a 6-pin small format interchangeable core, the figure-eight core used across BEST systems, and it is supplied less core so it can be pinned into an existing BEST master key system. Full size interchangeable core is a different, larger core footprint - the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in the C keyway in 643E aged bronze. FSIC cores do not drop into an SFIC prep, so the two systems have to be kept separate on a keying schedule.
12) I am retrofitting an Arrow interconnected lock or an Emtek handleset - is the BEST 1E the right cylinder?
Not for those chassis. The BEST 1E is a 1-1/8 inch mortise cylinder with a C161 clover cam suited to Arrow and Corbin Russwin deadbolts. For an Arrow JL interconnected lock or an Emtek handleset and deadbolt outside cylinder, the Medeco 1065140 is a 5-pin retrofit cylinder made for that application, and the Medeco 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece. Emtek also has its own CY4 cylinder sold individually.
13) Can I use the BEST 1E on a residential Kwikset-style deadbolt or handleset?
No - the BEST 1E is a threaded mortise cylinder cammed for Arrow and Corbin Russwin deadbolts and needs a mortise cylinder prep. Residential deadbolts of that type take a rim style lazy motion cylinder: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
14) What rings come with the BEST 1E cylinder?
It is supplied with the RP2 ring set for a 6-pin mortise application. The ring takes up the gap between the cylinder face and the door or trim so the cylinder seats flush, and different ring stacks are what let the same housing sit correctly at different trim depths.
15) How is the cylinder held in the lock body, and can it be twisted out?
A diagonal set screw mounts in the cylinder wall and clamps the housing in place. That is the standard anti-removal detail on a mortise cylinder. Back the set screw off through the lock's edge access before you try to unthread the cylinder, and snug it back down after.
16) What finish is this cylinder and will it match my other door hardware?
Satin chrome, 626. That is the most common commercial finish on levers, exit devices and mortise trim, so it usually matches existing openings in an office, school or healthcare building without a second thought. If your building is standardized on a bronze or brass finish, the face ring will read as a mismatch.
17) What is the cylinder body made of?
Machined from brass bar stock, which holds tolerances on the threads and the plug bore and resists corrosion. Paired with the satin chrome plating, it holds up on exterior and high-traffic openings.
18) Is there installation documentation for the BEST E Series cylinders?
Yes, BEST publishes an E Series Service Manual that covers the housing family, and ZenSupply carries it. For the lock itself, follow the deadbolt or mortise lock manufacturer's instructions, since the cylinder is a replacement part fitted into that device.
