TownSteel CRX-A-84-630-RH – Frequently Asked Questions

1) Will the TownSteel CRX-A-84 fit a 1-3/4 inch door?
That's the only thickness the CRX-A cylindrical lockset is built for: 1-3/4 inches, which is standard commercial door thickness. It mounts on wood or metal doors and uses through-bolt mounting with tamper-resistant screws. If your openings are 1-3/8 inch older interior doors, this is the wrong part and you'd need a lock rated across that range, like the Cal-Royal BA03 classroom lock, which covers 1-3/8 to 1-3/4 inch doors.
2) What backset do I order for the TownSteel CRX-A-84, and does it come in 5 inch?
Two backsets are offered: 2-3/4 inch, which is the standard commercial backset, and 5 inch for doors with wider stiles or where the existing prep sits farther from the edge. Measure from the door edge to the center of the bore before ordering. Both backsets are available in all four handings and in either cylinder option.
3) Does the TownSteel CRX-A-84 need to be handed when I order it?
Handing matters here. The CRX-A-84 is ordered as LH, LHR, RH, or RHR, so you have to determine the swing before you buy. Stand outside the door: if the hinges are on your left it's left hand, on your right it's right hand, and if the door swings toward you it's the reverse version. Get it wrong and the arch trim and key side end up on the wrong face of the door.
4) Can I key the TownSteel CRX-A-84 into our existing small format interchangeable core system?
Yes. The CRX-A-84 is offered with SFIC prep, less core, so you supply your own small format interchangeable core and it drops into the master key system already running in the building. The alternative order option is a standard cylinder. Either way it's a single cylinder lock, keyed from the outside only.
5) Will the TownSteel CRX-A-84 latch into the strike already in my frame?
The CRX-A ships with a 1-1/4 by 4-7/8 inch ASA strike, which is the standard commercial frame prep, so it drops into most existing metal frames without new cutting. The latch face plate is 1-1/8 inches. If your frame is prepped for a T-strike or a smaller residential lip strike, you'll be enlarging the frame cutout.
6) Is the TownSteel CRX-A-84 suitable for a behavioral health or psychiatric unit?
That's what it's built for. The CRX-A carries a 5-point ligature resistant stainless steel arch trim and TownSteel states it meets ligature resistant requirements, which is why it's recommended for high-risk areas in facilities housing patients at risk. Tamper-resistant mounting screws mean the trim can't be pulled apart with a common screwdriver. A conventional lever lockset in the same opening gives a patient an anchor point; this one does not.
7) How does classroom function work on the TownSteel CRX-A-84 and is it right for a patient room?
Classroom function means there is no locking button or thumbturn on the inside. The outside lever or trim is locked and unlocked only with a key, and the inside always retracts the latch for free egress. On a patient room or a classroom that is exactly what you want, because an occupant can never lock themselves in from within. If you need staff to secure the room without a key at the door, classroom is the wrong function and you should look at a storeroom or entrance function instead, such as the Cal-Royal BA05 storeroom lock or the Falcon K501 entrance lock with push-turnbutton.
8) What is the closest classroom function cylindrical lock to the TownSteel CRX-A-84 if the opening does not need ligature resistant trim?
The Cal-Royal BA03 is a classroom function cylindrical lock in the Barrington BA series with conventional lever trim. The CRX-A-84 is a Grade 1 classroom cylindrical lock built around a 5 point ligature resistant stainless steel arch trim with tamper resistant through-bolt mounting, which is what makes it suited to behavioral health and other at-risk areas. On a standard corridor or classroom door where nothing needs to defeat a tie-off point, the BA03 covers the same classroom keying behavior. Note the CRX-A-84 is Grade 1, while the BA03 is a Grade 2 ANSI F84 classroom lock, so if your spec calls out Grade 1 the BA03 will not satisfy it.
9) Which Grade 1 cylindrical lock should I use instead of the CRX-A-84 on a door thicker than 1-3/4 inches?
The Falcon K501 is a Grade 1 heavy duty cylindrical lock in the K series with a door thickness range of 1-3/8 to 2-1/4 inches, so it covers thicker leaves. The CRX-A-84 is built for 1-3/4 inch doors. The functions differ: the K501 is an entrance lock with push-turnbutton operation, while the CRX-A-84 is a classroom lock, so the keying behavior on the outside lever is not the same and the K501 does not carry ligature resistant trim.
10) Is the BEST 9KW a substitute for the TownSteel CRX-A-84?
No. The BEST 9KW is a heavy duty electromechanical cylindrical lock with remote control operation, meaning it needs power and a control input at the opening. The CRX-A-84 is a mechanical cylindrical lockset, keyed single cylinder, with no electrification. They share the cylindrical prep family but are different scopes of work: swapping one for the other changes whether the door needs wiring, a power transfer, and an access control head end. Use the 9KW when the door has to be released remotely, and the CRX-A-84 when the opening is key-operated and needs ligature resistant trim.
11) Is the TownSteel CRX-A-84 a Grade 1 lock, and will it hold up in a high traffic corridor?
ANSI Grade 1, heavy duty, and specified for commercial use. Grade 1 is the highest ANSI/BHMA cylindrical lock grade and the level institutional specs typically call for on corridor and patient room doors. Body is a cylindrical lock with stainless steel arch trim.
12) What is the difference between the TownSteel CRX-A-84 and a standard Grade 1 classroom lever like the Falcon K501?
Trim shape and the anti-ligature intent. The CRX-A-84 uses a 5-point ligature resistant stainless steel arch trim with tamper-resistant through-bolts, sized for 1-3/4 inch doors only. The Falcon K501 is a Grade 1 heavy duty cylindrical lock with a conventional lever, entrance function with push-turnbutton, and covers 1-3/8 to 2-1/4 inch doors. If the opening is a behavioral health room, the arch trim is the reason to buy the CRX-A. If it's a general office or corridor with mixed door thicknesses, the conventional lever has the wider fit range and a lower cost of install.
13) Can I standardize a whole floor on the TownSteel CRX-A series and still mix functions?
The CRX-A is a series, and the -84 is the classroom function within it. Ordering the same series across a floor gives you one trim appearance, one strike prep at 1-1/4 by 4-7/8 ASA, and one door thickness at 1-3/4 inches across every opening, with function varying by model. Spec the SFIC prep option throughout and every lock takes the same core, so the facility runs on a single key system.
14) Do I need an electrified or access-controlled lock instead of the TownSteel CRX-A-84?
The CRX-A-84 is a mechanical, key-operated cylindrical lockset with no electrified option in its ordering choices, which are backset, cylinder type, and handing. If the opening needs to be released or monitored from a nurse station or a card system, this isn't the part. The BEST 9KW Series is an electromechanical cylindrical lock with remote control operation and is the heavy duty option to look at for that.
15) Is the TownSteel CRX-A-84 a mortise lock or a cylindrical lock?
Cylindrical, bored through the door face rather than into a pocket in the door edge. That matters for retrofit: if your doors are already prepped with a standard 161 cylindrical bore you can install this without routing a mortise pocket. Doors currently carrying mortise locks have a rectangular pocket in the edge and swapping to a cylindrical lock leaves that pocket open, so you'd need a filler plate or a mortise-body replacement instead.
16) I need a fire rated Grade 1 cylindrical lock for a stairwell or corridor opening - is the CRX-A-84 the right part?
For a fire rated opening, look at the Falcon K501, which is a Grade 1 heavy duty cylindrical lock carrying a fire rating. The CRX-A-84 is a Grade 1 heavy duty cylindrical lock whose defining feature is 5 point ligature resistant arch trim for high-risk areas in facilities housing patients at risk; specify it where the ligature resistant trim is the requirement. Be aware the K501 is an entrance function with push-turnbutton locking rather than a classroom function, so confirm the function code on your door schedule before substituting.
17) What is the difference between the classroom function of the CRX-A-84 and the storeroom Cal-Royal BA05 for a school or clinic door?
Function is the deciding factor. The CRX-A-84 is a classroom function lock, so the outside lever is locked and unlocked by key and can be left unlocked for free passage during occupied hours. The Cal-Royal BA05 is a storeroom function lock in the Barrington BA series with a Grade 2 ANSI F86 deadlocking latch, where the outside lever stays locked at all times and entry is by key every time. Pick classroom where staff need to secure or release the room from the corridor side; pick storeroom where the door must never be left unsecured. The CRX-A-84 is also the Grade 1 option and the one with ligature resistant arch trim.
18) The door needs to be lockable from inside the room by pushbutton, not by key - what takes the place of the CRX-A-84?
The Cal-Royal BA00 is an entrance function cylindrical lock in the Barrington BA series with turn/push button locking, so an occupant secures the door from the inside without a key. The CRX-A-84 is a classroom function lock with a single cylinder keyed from the outside, which is deliberate on patient-area and classroom doors where you do not want the room secured from within. The BA00 fits doors 1-3/8 to 1-3/4 inches thick.
19) Can I standardize a facility on Cal-Royal Barrington locks and use them where the CRX-A-84 is specified?
Partly. The Barrington BA series covers the common functions with the BA00 entrance, BA03 classroom, BA04 communicating and BA05 storeroom, all fitting doors 1-3/8 to 1-3/4 inches thick, which makes it a coherent set for general corridor and office doors. Two things stop it short of the CRX-A-84: the Barrington classroom and storeroom locks are Grade 2 while the CRX-A-84 is Grade 1 heavy duty, and none of the Barrington functions carry the 5 point ligature resistant arch trim and tamper resistant screws. Use the Barrington set on the general openings and keep the CRX-A-84 on the patient-risk doors.
20) I am locking a pair of connecting patient rooms - does the CRX-A-84 handle a communicating opening?
For a communicating opening, the part to look at is the Cal-Royal BA04, an ANSI F80 Grade 2 communicating function cylindrical lock in the Barrington BA series, which is the function written for doors between two rooms that each need control. The CRX-A-84 is a classroom function lock, keyed single cylinder, intended for a corridor-to-room door rather than a room-to-room connector. If the connecting door is in a high-risk patient area, confirm the function on your schedule first, since the ligature resistant arch trim is only on the classroom function CRX-A-84.
