Certified to ANSI/BHMA A156.2-2011 Grade 1 and UL10C 3-Hour fire rated, this lockset features an independent torsion spring design that delivers effective lever support and long-term reliability. Available in clutched or rigid trim configurations across three trim styles, the CDC-84 accommodates most BHMA functions and is offered in 622 or 626 standard finishes for demanding institutional environments.

TownSteel TWS-CDC-84-S-626 – Frequently Asked Questions

1) What does the classroom function do on the TownSteel CDC-84 lock?
The CDC-84 is a classroom function cylindrical lockset, keyed on both sides (double cylinder). The outside lever is locked and unlocked by key only, with no push button or turn button on the inside, so a teacher or staff member controls the opening from the corridor side and the inside lever always retracts the latch for free egress. That key-only control is what keeps students from locking or unlocking the door themselves.
2) Is the TownSteel CDC-84 approved for a fire rated classroom door?
The CD/CDC Series cylindrical lockset is UL10C 3-hour rated, so it can go on a fire rated opening within that rating. It is also ANSI/BHMA A156.2-2011 Grade 1 certified, which is the level most school and institutional specs call for on corridor doors.
3) What is a clutched lever and why would I want it on a school door?
On the clutched CDC trim, forcing the lever when the lock is secured lets the lever spin free instead of transmitting that torque into the lock body and spindle. TownSteel offers the series in both clutched and rigid trims and calls out the clutched design for highly abusive environments, which is exactly the kind of door that gets hung on in a school or a detention corridor. An independent torsion spring keeps the lever from drooping over time.
4) Can I order a batch of TownSteel CDC-84 classroom locks keyed alike?
Yes. Keying is a required selection on the CDC-84: keyed different (the standard), keyed alike when you want one key to run multiple doors, or a specific key code if you are matching an existing system. If you pick key code, you enter that code with the order. For a wing of classrooms that all need to open on the same staff key, keyed alike is the selection.
5) What is the closest classroom-function cylindrical lock to the TownSteel CDC-84 if Grade 1 is not required?
The Cal-Royal BA03 is a classroom-function cylindrical lock in the Barrington BA series with the ANSI F84 classroom function at Grade 2, fitting doors 1-3/8 inch to 1-3/4 inch thick. The TownSteel CDC-84 is a classroom-function cylindrical lockset certified ANSI/BHMA A156.2-2011 Grade 1 and UL10C 3-hour rated, with clutched lever trim. If the opening is a school corridor or another high-abuse door, stay with the CDC-84; for a lower-traffic classroom or office door where Grade 2 satisfies the spec, the BA03 covers the same locking behavior.
6) I need a Grade 1 cylindrical lock for a thicker door than standard - what else is there besides the TownSteel CDC-84?
The Falcon K501 is a Grade 1 heavy duty cylindrical lock in the K series, fire rated, with a published door thickness range of 1-3/8 inch to 2-1/4 inch. It is an entrance function with push-turnbutton locking rather than classroom, so the key behavior differs: the K501 lets an occupant lock the outside lever from inside, while the TownSteel CDC-84 is a classroom lock operated by key from the outside. Match the function to how the room is controlled before substituting on thickness alone.
7) What lever styles and finishes does the TownSteel CDC-84 come in?
Three lever designs, Gala, Quest and Sentinel, each in 613 Satin Bronze Oil Rubbed or 626 Satin Chrome. All six combinations are orderable, so you can hold one lever shape across a building and split finishes by area, or the reverse.
8) How hard is the CDC-84 to install compared with a mortise lock?
It is a bored cylindrical lock, so it installs in a standard 161 cylindrical door prep rather than the deep mortise pocket a mortise lock needs. TownSteel builds it with heavy gauge mounting plates and roses, a low profile rose, and a removable thru-bolt with an adjustable mounting plate, which is what lets one lock cover a range of door prep conditions. For new classroom doors or a straight swap of an existing cylindrical lock, this is the faster install.
9) I need an entrance function lock, not classroom. What should I look at instead?
The CDC-84 is key-only control with no inside button, so it will not give you push button entrance locking. For a Grade 1 heavy duty entrance lock with a push-turnbutton, the Falcon K501 covers it and fits 1-3/8 to 2-1/4 inch doors with a fire rating. On lighter duty work the Cal-Royal BA00 entrance lock with turn/push button locking fits 1-3/8 to 1-3/4 inch doors.
10) Can I standardize a whole building on the CDC/CDC-84 platform with different functions on different doors?
Yes. Most BHMA functions are available in the CD/CDC Series, so storeroom, office and entrance openings can carry the same series, same lever design and same rose profile as the classroom CDC-84, with only the function code changing. That keeps one parts and keying program across the facility.
11) Can I use a storeroom lock instead of the TownSteel CDC-84 classroom lock?
They behave differently. The Cal-Royal BA05 is a storeroom-function cylindrical lock with a Grade 2 ANSI F86 deadlocking latch, meaning the outside lever stays locked at all times and a key is required for every entry. The TownSteel CDC-84 is a classroom function, where a key on the outside locks and unlocks the outside lever so the room can be left open during use. Use the BA05 for closets, mechanical rooms and supply storage; use the CDC-84 where staff need the door to stand unlocked for part of the day.
12) Is the Cal-Royal BA00 a substitute for the TownSteel CDC-84 on a classroom door?
No - the BA00 is an entrance-function lock in the Barrington BA series with turn/push button locking, fitting doors 1-3/8 inch to 1-3/4 inch. Its locking is controlled from the inside by the occupant, which most school and institutional classroom specs prohibit. The TownSteel CDC-84 is a classroom function lockset, keyed from the outside, and is ANSI/BHMA A156.2-2011 Grade 1 with a UL10C 3-hour fire rating. If the drawing calls for classroom function, the BA00 will not satisfy it.
13) What should I look at instead of the TownSteel CDC-84 if the door needs to be released remotely or tied into access control?
The BEST 9KW series is a heavy duty electromechanical cylindrical lock with remote control operation, so it can be unlocked from a control point rather than only at the door. The TownSteel CDC-84 is a fully mechanical classroom cylindrical lockset, Grade 1 and UL10C 3-hour rated, keyed at the lever. Choose the 9KW when the opening is part of an electronic access or lockdown scheme, and the CDC-84 when the door is managed with keys alone.
14) What lock handles a pair of connecting rooms rather than the single classroom door the TownSteel CDC-84 covers?
The Cal-Royal BA04 is a communicating-function cylindrical lock, ANSI F80 Grade 2, for doors 1-3/8 inch to 1-3/4 inch thick - the function intended for openings between two rooms where each side can be controlled. The TownSteel CDC-84 is a classroom-function Grade 1 lockset with clutched lever trim for a single corridor-to-room door. Order by function per opening rather than standardizing one lock across both conditions.
