TownSteel TWS-DRX-09-630 – Frequently Asked Questions

1) What does the TownSteel DRX-09 deadbolt function actually do when someone turns the inside thumbturn?
The DRX-09 is the F09 function: the deadbolt is thrown by key from the outside, and the inside thumbturn only retracts the bolt, it cannot project it. That is why it gets called a classroom deadbolt, a student or patient inside can always get out but cannot lock the door. If you need the thumbturn to both throw and retract, order the 07 function instead; if you want key-only operation with no inside trim at all, that is the 18.
2) Will the DRX-09 fit a 1-3/8 inch door?
No. The DRX-09 is built for 1-3/4 inch doors only, which is the standard commercial thickness. For a thinner 1-3/8 inch leaf you need a different lock, for example the Cal-Royal Barrington BA series covers 1-3/8 to 1-3/4 inch, and the Falcon K501 covers 1-3/8 to 2-1/4 inch.
3) Why choose an anti-ligature thumbturn deadbolt over a standard one for a behavioral health room?
A conventional deadbolt thumbturn gives a protruding lever that a cord or sheet can be looped over. The DRX health safety thumbturn is shaped to shed that load, which is why TownSteel positions it for health care facilities, detention centers, and other high risk areas. The turn piece is also ADA compliant, so it still meets accessible operation requirements on patient room and restroom doors.
4) What faceplate and strike prep does the TownSteel DRX deadbolt use?
The faceplate measures 1-1/4 x 4-5/8 inches and the standard strike is 1-1/8 x 3-1/2 inches. Compare those to the mortise pocket and frame strike cutout already in your door before you commit, since a retrofit into an existing prep only works if the edge and frame openings match.
5) Is the TownSteel DRX-09 Grade 1 and UL Listed for an institutional spec?
Yes. The DRX carries ANSI/BHMA A156.13 Grade 1 certification and is UL Listed, and it meets BAA and ADA requirements. That combination is what most school, hospital, and government specs call out for a heavy duty commercial deadbolt.
6) Can I get the DRX-09 deadbolt prepped for our small format interchangeable core system?
Yes. Two cylinder builds are offered: a standard cylinder, or SFIC prep less core if you are keying it into an existing small format interchangeable core system with your own cores. Both come in 630 satin stainless steel.
7) Can I order several DRX-09 deadbolts keyed alike for one building?
Yes. Keying is a required selection at order: KD keyed different is standard, KA keys multiple locks alike, and a Key Code option lets you specify special keying to match an existing system, with a text field for the code itself. If you take the SFIC prep less core version, you supply the cores and key them yourself.
8) What is the difference between the TownSteel DRX-09 deadbolt and the Falcon K501 for a Grade 1 opening?
Both are Grade 1 heavy duty commercial hardware, but they do different jobs on the door. The TownSteel DRX-09 is a deadbolt with a cylinder outside and an anti-ligature thumbturn inside, with no knob or lever and no latch - it is a secondary lock that gets added alongside whatever latching device is already on the door. The Falcon K501 is an entrance cylindrical lock with push-turnbutton function, so it carries the knob or lever trim and the latch that operates the door. If the opening needs a latching handle set, the K501 is the device; if it needs added bolt security on a door that already latches, the DRX-09 is.
9) I need a classroom function lock, not a deadbolt - what should I use instead of the TownSteel DRX-09?
The DRX-09 uses classroom-style deadbolt function F09, where the key from outside and the thumbturn inside retract the bolt but the inside turn does not project it. It is still a deadbolt with no lever trim. For a true classroom latching lockset, the Cal-Royal BA03 is a classroom cylindrical lock in the Barrington BA series with ANSI F84 function, which gives you the operating trim and latch on the door. Many schools use both together - the BA03 as the operating lockset and a deadbolt for secondary security.
10) Does the DRX-09 deadbolt need to be ordered left or right hand?
No handing to specify. The DRX-09 is non-handed, so one part number covers both left and right hand openings, which makes it easier to stock a single deadbolt across a floor of rooms.
11) Is the DRX-09 a complete lock or an add-on deadbolt?
It is a deadbolt only, cylinder outside by thumbturn inside, with no knob or lever and no latchbolt. It is used above a passage set or a latch-only lockset to add the security bolt. If you want one device that both latches and locks, look at a keyed cylindrical lockset instead, such as the Cal-Royal BA03 classroom function or the Falcon K501 Grade 1 entrance lock.
12) Is the Cal-Royal BA05 storeroom lock a substitute for the TownSteel DRX-09?
No. The BA05 is a storeroom cylindrical lock in the Barrington BA series with a Grade 2 ANSI F86 deadlocking latch, fitting doors 1-3/8 inch to 1-3/4 inch. The DRX-09 is a Grade 1 deadbolt with cylinder outside and anti-ligature thumbturn inside. The BA05 is the door's operating lockset; the DRX-09 adds a separate bolt and thumbturn. They mount in different preps and one does not replace the other.
13) For a behavioral health room, is the TownSteel DRX-09 or the BEST 9KW the better choice?
They solve different problems. The DRX-09 is a mechanical Grade 1 deadbolt whose thumbturn is shaped to reduce ligature risk, which is why it is specified in health care facilities and detention settings, and the thumbturn meets ADA requirements. The BEST 9KW is a heavy duty electromechanical cylindrical lock with remote control operation, so it suits openings where staff need to release or secure the door from a control point and where power and wiring are available. A room that needs anti-ligature mechanical bolt security takes the DRX-09; one that needs remote electrified control takes the 9KW.
14) What is the difference between the TownSteel DRX-09 and the Cal-Royal BA00 entrance lock for an apartment door?
The BA00 is an entrance cylindrical lock in the Barrington BA series with turn/push button locking, fitting doors 1-3/8 inch to 1-3/4 inch - it is the knob or lever set the resident uses to operate and lock the door. The DRX-09 is a Grade 1 deadbolt for 1-3/4 inch doors, keyed outside with a thumbturn inside, and adds a bolt above the lockset rather than replacing it. A typical apartment entry uses a lockset like the BA00 plus a deadbolt.
15) I need a pair of connecting hotel rooms locked from both sides - does the DRX-09 do that?
The DRX-09 is a single cylinder deadbolt, keyed from one side with a thumbturn on the other, so it does not give key control from both faces. For a connecting door between two rooms, the Cal-Royal BA04 is a communicating cylindrical lock in the Barrington BA series with ANSI F80 Grade 2 function, sized for 1-3/8 inch to 1-3/4 inch doors, which is the function written for that opening.
16) Does the TownSteel DRX-09 or the Falcon K501 go on a fire-rated door?
The Falcon K501 is listed with a fire rating, so it is the one to specify when the drawing calls for a rated cylindrical entrance lock. The DRX-09 is an ANSI/BHMA A156.13 Grade 1 certified, UL Listed deadbolt that meets BAA and ADA requirements. On a rated opening, confirm the full assembly - deadbolts are often restricted on fire doors depending on the opening's listing - and have the door manufacturer confirm the prep.
17) We already use satin stainless hardware throughout the building. Will this deadbolt match?
The DRX-09 is supplied in 630 satin stainless steel, the standard brushed stainless finish used across most commercial and healthcare openings, so it will sit consistently with 630 levers, push plates, and hinges already on the doors.
