TownSteel TWS-CDC-109-S-626 – Frequently Asked Questions

1) What does the Entry/Office function on the TownSteel CDC-109 actually do at the door?
The CDC-109 is the entrance/office function in TownSteel's CDC cylindrical line. The outside lever is locked and unlocked by key, and the inside lever always retracts the latch for free egress. It's the standard choice for a tenant suite door, an office, or a stockroom where staff need to lock up on the way out but the door has to open from inside at all times.
2) Is the TownSteel CDC-109 lockset fire rated for a labeled door?
It is. The CD/CDC Series carries a UL10C 3-hour rating, so it can go on a labeled opening up to a 3-hour rating. It's also ANSI/BHMA A156.2-2011 Grade 1 certified, which is the level most institutional and government specs call for on corridor and tenant doors.
3) What is a clutched lever and why would I pay for one on an office door?
On the clutched CDC trim, the outside lever spins free when the lock is secured instead of transmitting force into the lock chassis. Someone hanging on the lever or yanking it does not torque the internals. TownSteel offers the CDC line specifically for highly abusive environments, which is why it shows up in schools, correctional support areas, shelters, and high-traffic multifamily. If your doors do not see that kind of abuse, the rigid trim version of the same series does the job.
4) Can I order a batch of CDC-109 locks keyed alike for one building?
Yes. Keying is a required selection when you order: KD keyed different is the standard, KA keyed alike puts every lock in the group on one key, and there's a key code option if you need the locks cut to an existing code your building already uses. If you pick key code, enter the code in the text field with the order. For a property manager standardizing a floor or a set of suites, KA is the one you want.
5) Is a Grade 2 lock like the Cal-Royal Barrington enough, or do I need the Grade 1 CDC-109?
Depends on the traffic and the spec. The Cal-Royal BA00 is a Grade 2 entrance cylindrical lock with turn/push button locking that fits 1-3/8 to 1-3/4 inch doors, and it's a reasonable pick for light commercial or residential-grade openings. The CDC-109 is ANSI/BHMA A156.2-2011 Grade 1 with a clutched lever, which is what institutional, healthcare, education and government specs normally demand on corridor and tenant entry doors. If the drawing says Grade 1, the Barrington will not pass.
6) What is the closest Grade 1 equivalent to the TownSteel CDC-109 entrance lock from another brand?
The Falcon K501 is the closest match. It is a Grade 1 heavy duty entrance cylindrical lock with push-turnbutton function, which lines up with the CDC-109's Grade 1 heavy duty entrance/office cylindrical lockset. The Falcon K501 is fire rated and fits doors 1-3/8 inch to 2-1/4 inch thick. The CDC-109 differs in that it uses a clutched lever trim, where the lever spins free under force rather than transmitting it to the latch.
7) I need a classroom function lock, not entry/office - what should I order instead of the TownSteel CDC-109?
The CDC-109 is an entrance/office function lockset, which is not the right function for a classroom door where the outside lever must be locked and unlocked by key only. The Cal-Royal BA03 in the Barrington BA series is a classroom cylindrical lock with the Grade 2 ANSI F84 function and fits doors 1-3/8 inch to 1-3/4 inch thick. TownSteel also builds most BHMA functions in the CD/CDC series, so a different CDC function number is the route if you want to stay in the same series and trim.
8) Which lever designs and finishes can I get the CDC-109 in?
Three lever styles: Gala, Quest, and Sentinel. Each comes in 613 Satin Bronze Oil Rubbed and 626 Satin Chrome. If you're matching existing openings in a building, 626 satin chrome is the common commercial default and 613 is the dark oil-rubbed bronze look.
9) How does the TownSteel CDC-109 compare to the Falcon K501 entrance lock?
Both are Grade 1 heavy duty keyed entrance cylindrical locks. The Falcon K501 is a push-turnbutton entrance function and is listed as fire rated, with a door thickness range of 1-3/8 to 2-1/4 inches. The CDC-109 is key-operated entrance/office with a clutched lever and a UL10C 3-hour rating. The real split is the clutch: pick the CDC-109 where levers get abused, the K501 where you want the inside turnbutton to lock the outside lever without a key.
10) I need a lock that stays locked outside at all times with key access only, not entry/office. What should I use?
That's storeroom function, not what the CDC-109 does. The CDC-109 outside lever can be left unlocked for normal business hours. For an always-locked outside lever with key-only entry, look at a storeroom function lock such as the Cal-Royal BA05, a Grade 2 storeroom cylindrical lock with an ANSI F86 deadlocking latch. For a classroom opening locked and unlocked from outside by key only, the Cal-Royal BA03 is the Grade 2 ANSI F84 classroom function.
11) Is the TownSteel CDC-109 a mortise lock or a bored cylindrical lock?
It's a bored cylindrical lockset, so it installs into a standard cross-bore and edge-bore prep rather than a mortise pocket. If the door you're replacing has a rectangular mortise case cut into the edge, this is not a drop-in and you'd need a mortise lock instead.
12) Is there a lighter-duty entrance cylindrical lock I can use instead of the TownSteel CDC-109 on a low-traffic interior office door?
Yes. The Cal-Royal BA00 from the Barrington BA series is an entrance cylindrical lock with turn/push button locking that fits doors 1-3/8 inch to 1-3/4 inch thick. The TownSteel CDC-109 is a Grade 1 heavy duty commercial lockset with a clutched lever for abusive environments, so the BA00 is the option when the opening does not need that level of construction. Check the door thickness first, since the BA00 tops out at 1-3/4 inch.
13) Can I swap the BEST 9KW in place of a TownSteel CDC-109?
Not as a like-for-like. The BEST 9KW is an electromechanical cylindrical lock with remote control operation, so it requires power and a control system at the opening. The TownSteel CDC-109 is a purely mechanical Grade 1 cylindrical lockset operated by key and lever. Both are heavy duty cylindrical locks, so they prep into a comparable bored door, but choosing the 9KW means adding wiring and access control that the CDC-109 does not need.
14) Is a communicating lock like the Cal-Royal BA04 the same thing as the TownSteel CDC-109 entry/office lock?
No. The Cal-Royal BA04 is a communicating cylindrical lock, ANSI F80 Grade 2, for doors 1-3/8 inch to 1-3/4 inch thick - a function built for a door between two occupied spaces where either side can be locked out. The TownSteel CDC-109 is an entrance/office function Grade 1 lockset, the standard choice for a keyed office or tenant entry door. They are not interchangeable functions even though both are bored cylindrical locks.
15) What holds up on a TownSteel CDC lever that sags on cheaper locks?
Lever sag is the usual failure on cylindrical trim. The CDC/CD uses an independent torsion spring design to support the lever, plus heavy gauge mounting plates and roses. Installation uses a removable thru-bolt and an adjustable mounting plate, which is what lets a single lock body suit varying door prep without shimming.
16) Is the CDC-109 suitable for residential doors or is it commercial only?
It's built and catalogued as commercial heavy duty hardware. Nothing stops you putting it on a residential door, but the Grade 1 chassis, clutched lever and 3-hour fire rating are aimed at apartment entries, offices, schools and institutional openings where the lock gets cycled hard every day.
