TownSteel CRX-K-86-630 – Frequently Asked Questions

1) Will the TownSteel CRX-K-86 fit a standard 1-3/4 inch commercial door?
Yes. The CRX-K-86 ligature-resistant knob lockset covers doors from 1-3/4 inches up to 2 inches thick, so a standard commercial 1-3/4 inch leaf is the low end of its range. It will not work on a 1-3/8 inch door, which rules it out for older interior openings. It mounts on either wood or metal doors.
2) What does storeroom function mean on a behavioral health patient room door?
Storeroom function on the CRX-K-86 means the outside knob is always locked and only a key retracts the latch. The inside knob always retracts the latch for free egress, and there is no way to leave the outside unlocked. That is why it is specified on patient rooms, med rooms and utility closets in behavioral and psychiatric facilities: staff control entry with a key, the occupant is never locked in, and there is no thumbturn or button on the lock that could be defeated. It is a single cylinder lock, so one key cylinder on the outside.
3) Will the CRX-K-86 latch into my existing ASA strike prep?
It should. The CRX-K-86 ships with a 1-1/4 x 4-7/8 inch ASA strike, which is the standard commercial frame prep, and the latch face plate is 1-1/8 x 2-1/4 inches with square corners. If your frame is cut for an ASA strike and your door edge is prepped square corner, it drops in. Frames with a round corner or full lip residential strike will need to be modified.
4) What makes a ligature-resistant knob different from a regular commercial knob?
The CRX-K knob is shaped in stainless steel so a cord, sheet or strap cannot be anchored on it, which is the failure point of a standard round knob or any lever. It also uses tamper-resistant mounting screws so the lock cannot be taken apart from the room side with a common driver. Those two things are why it is specified in rooms housing patients at risk rather than a conventional Grade 1 knob lock.
5) What is the closest Grade 1 storeroom knob lock to the TownSteel CRX-K-86 if a ligature-resistant knob is not required?
The Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a single cylinder and a 2-3/4 inch backset, which matches the CRX-K-86 on grade, duty level, function and keyed configuration. The difference is the knob itself: the CRX-K-86 uses a ligature-resistant stainless steel knob with tamper-resistant mounting screws for behavioral and psychiatric healthcare openings, while the 8XG04 uses a conventional knob. On a standard back-of-house storeroom door where patient safety is not a factor, the 8XG04 covers the same function.
6) The door is 2 inches thick. Which knob locks besides the CRX-K-86 will fit?
The CRX-K-86 is built for 1-3/4 inch to 2 inch doors, so it fits a full 2 inch leaf directly. Among other knob locks, the Corbin Russwin CK4310 passage knob and the CK4851 entrance/office knob both cover 1-3/8 to 2 inches, and the Falcon X101 Grade 1 passage knobset covers 1-3/8 to 2-1/4 inches. Many Grade 2 and Grade 3 knobsets, such as the Dexter C2000 entry knob, stop at 1-3/4 inches and will not reach.
7) What should I use instead of the CRX-K-86 on an office door that needs to stay unlocked during the day?
The CRX-K-86 is a storeroom function, so the outside knob is always locked and entry is by key only. For an opening where staff need to leave the outside knob free during business hours, an entrance/office function is the right lock: the BEST 8K Series entrance function knob lock is Grade 1 heavy duty with a single cylinder, and the Corbin Russwin CK4851 is a Grade 1 entrance/office cylindrical knob lock with a conventional cylinder for doors 1-3/8 to 2 inches thick.
8) Is the CRX-K-86 rated for high traffic institutional use?
It is ANSI Grade 1 and classed heavy duty, which is the top commercial grade and the level normally specified for hospital corridors, patient rooms and other high-cycle institutional openings. Standardizing a wing on it is reasonable from a durability standpoint.
9) Can I get a set of these keyed alike across a floor?
Yes. Keying is a required selection on the CRX-K-86: keyed different is the standard, keyed alike is available when you want one key to open multiple locks, and you can supply a specific key code for special keying. If you are ordering a run of doors for one wing, pick keyed alike or give the code you already use in the building.
10) Is the Sargent 6G04 an acceptable substitute for the TownSteel CRX-K-86 storeroom knob lock?
Only where a lower grade is acceptable. The Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder, so it keys and functions the same way, but the CRX-K-86 is Grade 1 heavy duty. If the spec on the door calls for ANSI Grade 1, the 6G04 will not meet it, and it does not carry the ligature-resistant knob or tamper-resistant mounting screws the CRX-K-86 uses for at-risk patient areas.
11) Which knob lock should I pair with the CRX-K-86 on a classroom-type opening where the outside knob needs to be locked and unlocked by key?
The Dexter C2000 Series classroom cylindrical ball knob lock is a Grade 2 keyed classroom function for doors 1-3/8 to 1-3/4 inches thick. It differs from the CRX-K-86 in that classroom function lets a key lock and unlock the outside knob, while the CRX-K-86 storeroom function keeps the outside knob locked at all times. Note the grade difference as well, since the CRX-K-86 is Grade 1 heavy duty.
12) Is the Imperial USA ED-BKL580 storeroom knob trim the same thing as the TownSteel CRX-K-86?
No. The ED-BKL580 is knob trim in the ED-500 series, meaning it is the outside storeroom-function trim that mounts to an exit device, not a standalone lock. The CRX-K-86 is a complete cylindrical lockset with a latch, an ASA strike of 1-1/4 inch by 4-7/8 inch and a 1-1/8 inch by 2-1/4 inch square corner face plate. If the door already has a rim or mortise exit device, the trim is what you want; if the door is bored 161 for a cylindrical lock, the CRX-K-86 is.
13) I need a non-keyed knob for a patient corridor door instead of the keyed CRX-K-86. What are the options?
The CRX-K-86 is a single cylinder keyed storeroom lock. For a latching but non-keyed opening, the Falcon X101 is a Grade 1 heavy duty passage knobset with an interchangeable core prep and fits doors 1-3/8 to 2-1/4 inches, and the Corbin Russwin CK4310 is a Grade 1 non-keyed passage/closet knob lock for 1-3/8 to 2 inch doors. Neither carries the ligature-resistant knob design of the CRX-K-86, so confirm with the facility whether the opening falls inside the at-risk area.
14) What finish does the CRX-K-86 come in?
One finish only, 630 satin stainless steel, on both backset options. That is the standard institutional finish, so it matches typical hospital and behavioral facility hardware sets without a special order.
15) For a dummy knob to match a CRX-K-86 on the inactive leaf of a pair, what is available?
The CRX-K-86 is a latching cylindrical lockset, not a dummy. For a non-latching pull on an inactive leaf, the Schlage A170 is a Grade 2 single dummy trim knob for doors 1-3/8 to 1-7/8 inches, and the BEST 6K Series single dummy trim is a Grade 2 medium duty non-keyed knob. Neither will match the ligature-resistant stainless steel knob profile of the CRX-K-86, so in a behavioral healthcare area confirm the dummy trim meets the same requirement before specifying.
