TownSteel TWS-CDC-86-S-626 – Frequently Asked Questions

1) What does storeroom function mean on the TownSteel CDC-86, and where should I use it?
Storeroom function means the outside lever is always locked and retracts the latch only with a key; the inside lever is always free for egress. There's no button or thumbturn to leave it unsecured, which is why it gets used on mechanical rooms, electrical closets, stock rooms, and janitor closets where the door has to stay locked behind anyone who passes through. If you need staff to be able to leave the door unlocked during the day, an entrance function like the Cal-Royal BA00 with turn/push button locking is the one to look at instead.
2) Is the TownSteel CDC-86 lockset approved for a fire rated door?
It is. The CDC/CD Series cylindrical lockset is UL10C rated for 3 hours, so it can go on a labeled fire door assembly up to that rating. Storeroom function suits fire doors as well, since the latch stays deadlocked and the inside lever always gives free egress.
3) Is the CDC-86 tough enough for a high school or dorm corridor?
Yes. It is ANSI/BHMA A156.2-2011 Grade 1 certified, which is the top commercial cylindrical lock grade, and it is built as a heavy duty commercial lock. The CDC version adds a clutched lever: force the lever when the lock is secured and the lever spins free instead of transferring the load into the chassis. That is the reason TownSteel offers the clutched trim for abusive environments, and it is the version most schools and student housing specify. A rigid trim is also offered in the series if you do not need the clutch.
4) Can I order several CDC-86 locks keyed alike so one key opens all of them?
Yes. Keying is a required selection: keyed different is the standard, keyed alike puts multiple locks on one key, and there is a key code option if you have to match an existing system, with a field to enter that code on the order. Property managers replacing a run of storage or utility doors usually take keyed alike; if you are matching a building master, use the key code option and supply the code.
5) What is a Grade 1 alternative to the TownSteel CDC-86 if I want a different brand?
The Falcon K501 from the K Series is the closest Grade 1 heavy duty cylindrical lock we carry from another brand, and it is fire rated with a stated door thickness range of 1-3/8 to 2-1/4 inches. Note the difference in function though: the K501 is entrance with a push-turnbutton, meaning someone can leave the door unlocked from inside. The CDC-86 is storeroom, always locked outside, key only. They are not interchangeable if the door has to stay secure.
6) I need a classroom lock, not a storeroom lock. Is the CDC-86 the wrong part?
For a classroom you want the outside lever unlocked by default and lockable by key; the CDC-86 is storeroom, so the outside lever is locked at all times and only a key gets you in. Wrong function for a classroom door. The CDC series does cover most BHMA functions, so there is a classroom variant of the same lock, and the Cal-Royal BA03 Barrington is a Grade 2 classroom option with ANSI F84 function fitting 1-3/8 to 1-3/4 inch doors.
7) What is the closest storeroom-function cylindrical lock to the TownSteel CDC-86 if Grade 1 is not required?
The Cal-Royal BA05 is the nearest storeroom-function substitute. It is a storeroom cylindrical lock in the Barrington BA series carrying a Grade 2 ANSI F86 deadlocking latch and fits doors 1-3/8 inch to 1-3/4 inch thick. The TownSteel CDC-86 is a heavy duty Grade 1 storeroom cylindrical lockset with a clutched lever. Both keep the outside lever locked at all times and release by key, so the operating behavior on a storeroom or utility door is the same; the difference is the ANSI/BHMA grade and duty level behind it, plus the CDC-86 clutch that spins the lever free under force rather than transmitting it to the chassis.
8) If the opening needs a Grade 1 lever but occupants must be able to leave it unlocked, what should be used instead of the CDC-86?
Use the Falcon K501. It is a Grade 1 heavy duty entrance cylindrical lock with a push-turnbutton function, fire rated, in the Falcon K series, and fits doors 1-3/8 inch to 2-1/4 inch thick. The turnbutton lets staff lock and unlock the outside lever from inside the room. The TownSteel CDC-86 is a Grade 1 heavy duty storeroom lock, which has no turnbutton at all - the outside lever stays locked permanently and only a key retracts the latch. Same grade and duty class, different intent: the K501 for offices and suites that get unlocked during the day, the CDC-86 for closets, mechanical rooms and stock rooms that should never be left open.
9) What is the difference between the clutched CDC and the rigid CD cylindrical lock?
Same chassis family, different lever behavior. On the clutched CDC, the outside lever disengages from the retractor when the lock is secured, so someone hanging on it or kicking it down cannot torque the internals. The rigid CD lever stays fixed to the chassis. Pick clutched for corridors, stairwells, dorms and public restrooms; rigid is fine for back-of-house doors that only staff touch. Both trims are offered in the series.
10) What lever designs and finishes can I get the CDC-86 storeroom lock in?
Three lever styles, Gala, Quest and Sentinel, each in 613 Satin Bronze Oil Rubbed or 626 Satin Chrome. If you are matching existing openings in a building, 626 is the usual commercial standard and 613 is the dark oil rubbed bronze look. Pick one lever design and stay with it across the floor so the hardware reads consistently.
11) Does the CDC-86 need a special door prep or can it go into an existing 161 bore?
It is a bored cylindrical lockset, so it installs into the standard cross-bore and edge-bore prep that any other commercial cylindrical lock uses. TownSteel publishes a template and installation guide for the CD/CDC, and the chassis uses an adjustable mounting plate with removable thru-bolts, so it can be set up on site rather than ordered pre-configured.
12) Do I have to specify handing when I order a CDC-86 cylindrical lock?
No. Cylindrical locksets like the CDC-86 are non-handed, so one lock covers left and right hand openings. Choose the lever style, the finish and the keying, and that is the order complete.
13) Is there a cheaper storeroom cylindrical lock than the CDC-86 for lighter duty doors?
The Cal-Royal BA05 from the Barrington series is a storeroom cylindrical lock built to Grade 2 with an ANSI F86 deadlocking latch, and it fits doors 1-3/8 to 1-3/4 inches. Grade 2 is a lighter commercial duty level than the Grade 1 CDC-86, so it suits interior storage doors in low traffic buildings. For school corridors, dorms or anything that takes abuse, stay with the Grade 1 clutched CDC.
14) Is the Cal-Royal BA03 classroom lock a substitute for the TownSteel CDC-86?
No - they are different functions and behave differently on the door. The BA03 is a classroom cylindrical lock with a Grade 2 ANSI F84 function, meaning a key on the outside locks and unlocks the outside lever so an instructor can secure the room and then leave it unlocked. The TownSteel CDC-86 is a Grade 1 storeroom lock: the outside lever is fixed in the locked position and the key only retracts the latch for passage, never leaving the lever free. If you are replacing a classroom lock, the BA03 matches the behavior; if you are securing a storage or mechanical room, the CDC-86 does.
15) We want to control a stock room door remotely rather than by key - what replaces the TownSteel CDC-86?
The BEST 9KW is the electromechanical route. It is a heavy duty cylindrical lock in the 9KW series built for remote control operation, so the opening is released from an access control panel or a remote station instead of at the door. The TownSteel CDC-86 is a purely mechanical heavy duty Grade 1 cylindrical lockset - key in, latch retracts, no wiring. Choosing the 9KW means bringing power and control wiring to the opening; the CDC-86 needs only the standard bored prep and a key system.
16) For an apartment unit entry door, is the CDC-86 the right TownSteel-class lock or should we look at an entrance function?
A storeroom function is generally wrong for a unit entry. The TownSteel CDC-86 is a Grade 1 heavy duty storeroom lock, so the outside lever never unlocks and the resident cannot leave the door on latch. For unit entries the Cal-Royal BA00 is an entrance cylindrical lock in the Barrington BA series with turn/push button locking for doors 1-3/8 inch to 1-3/4 inch thick, letting the occupant control the outside lever from inside. Reserve the CDC-86 for the building's storage, electrical and janitor closets where permanent locking is the point.
17) Which cylindrical lock handles a thicker door than the standard 1-3/4 inch when the CDC-86 is being specified?
The Falcon K501 is the option in the comparable set with a published range up to 2-1/4 inch, covering doors from 1-3/8 inch to 2-1/4 inch; it is a Grade 1 heavy duty fire rated entrance lock in the K series. The Cal-Royal Barrington BA locks - BA00, BA03, BA04 and BA05 - are all specified for 1-3/8 inch to 1-3/4 inch doors. If the opening is a thick door and the function required is entrance, the K501 covers it; if you need the storeroom function of the TownSteel CDC-86 on an unusual door thickness, confirm the thickness against the CD/CDC installation template before ordering.
18) Does the CDC-86 lever go sloppy over time like cheaper levers do?
The CD/CDC chassis uses an independent torsion spring to support the lever rather than relying on the retractor, which is what keeps a lever from drooping after heavy use. It also runs heavy gauge mounting plates and roses with a low profile rose design, so the trim stays tight to the door face.
19) Is the CDC-86 a residential lock or strictly commercial?
Strictly commercial. It is a Grade 1 heavy duty commercial cylindrical lockset, built for institutional and MRO use, not a residential knob set. Grade 1 is the highest ANSI/BHMA durability tier for bored locks and is what most government, healthcare and education specs call for.
20) What is the difference between the CDC-86 and the Cal-Royal BA04 for a pair of connecting doors?
The BA04 is a communicating lock, ANSI F80 Grade 2, in the Barrington BA series for 1-3/8 inch to 1-3/4 inch doors - the function used between adjoining rooms where each side needs its own key control of the latch. The TownSteel CDC-86 is a Grade 1 heavy duty storeroom lock with a single secured side and a permanently locked outside lever. They are not interchangeable: a communicating opening needs the BA04 function, and a CDC-86 on that door would leave one side unable to operate it without a key.
