BEST 9K37E14CSTK626 – Frequently Asked Questions

1) How does the service station function on the BEST 9K lock actually work day to day?
The inside lever on the 9K service station lock is always unlocked and cannot be locked, so anyone inside can always get out by turning the lever. The outside lever only turns when the inside push button is out, or when a key is turned in the outside lever. Push the button in and the outside lever is dead until someone keys it or the button is released. That makes it a controlled-access opening where free egress is never in question.
2) What door thickness does the BEST 9K cylindrical lever lock fit, and can it go on a 1-3/8 inch door?
Standard range is 1-3/4 inch through 2-1/4 inch. For a 1-3/8 inch door, spacers are available to make it work. Door prep is a 2-1/8 inch diameter bore per ANSI A115.2, plus two 5/16 inch through-bolt holes at the 12 and 6 o'clock positions.
3) Will the BEST 9K lock latch into my existing strike?
The standard latch throws 9/16 inch and ships against a 2-3/4 x 1-1/8 inch strike with a curved lip and box. You can also order it with the S3 4-7/8 inch ANSI strike or the STK 2-3/4 inch ANSI strike. If your frame is already prepped for a 4-7/8 inch ANSI strike, order S3 and you drop into the existing frame cutout. If the frame carries the shorter 2-3/4 inch strike, order STK.
4) Does this BEST lever lock need to be ordered left or right hand?
No handing to specify. The 9K cylindrical lever is non-handed, so one part number covers both left and right hand doors. That is useful for a property manager stocking spares across a building, since a single lock covers any opening in the fleet.
5) What backset options are there on the BEST 9K, and which do I need for a wide stile aluminum or a narrow-frame door?
Three backsets: 2-3/4 inch standard, plus 3-3/4 inch and 5 inch. The 2-3/4 inch covers standard commercial hollow metal and wood doors. The 3-3/4 and 5 inch backsets exist for doors where the bore has to sit further from the edge, such as wide-stile or narrow-frame openings with rail or glazing clearance issues. Measure from the door edge to the center of the existing bore before you order.
6) Is the BEST 9K service station lock approved for a fire rated door?
It is UL listed for use on 3-hour A label single or double swinging doors. It also carries BHMA listing to A156.2, Series 4000, Grade 1, and the function is ANSI F92. For an institutional spec sheet calling out Grade 1 cylindrical on a fire opening, that is the combination you need.
7) Can I key the BEST 9K into my existing master key system?
The 9K is interchangeable core ready and keyed as a single cylinder, so it takes an IC core that can be pulled and swapped without taking the lock apart. That lets a facility rekey an opening in seconds and roll the lock into an existing master keying hierarchy rather than building a separate system for it.
8) Which Grade 1 lever lock should I use on an opening that needs no locking at all?
The BEST 9K service station lock is a keyed single cylinder lock, so it is more hardware than a corridor or closet door needs. For non-keyed Grade 1 passage function, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock rated for 1-3/8 inch to 2-1/4 inch doors with a fire rating, the Dexter C1000 passage is a Grade 1 clutching non-keyed passage lever for 1-3/8 inch to 1-3/4 inch doors, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever for 1-3/4 inch to 2 inch doors. All three hold Grade 1 while dropping the cylinder.
9) What should I specify instead of the BEST 9K service station lock on a patient room or utility door where no push button is wanted?
Service station function on the BEST 9K relies on an inside push button, which is exactly what is avoided in behavioral health and some utility rooms. Asylum function has no button and is key operated from both sides: the Dexter C1000 asylum is a Grade 1 asylum/institution/utility cylindrical lock for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum cylindrical lock with a ball knob and a conventional cylinder in Schlage C keyway. Note the Arrow uses a knob rather than a lever, which matters where lever trim is required.
10) What lever, rose and finish choices do I have to specify when ordering a BEST 9K?
Four things beyond backset and strike. Lever style: contour with angle return, curved with return, or curved without return. Rose: C rose at 3 inch convex or D rose at 3-1/2 inch convex. Finish: bright brass 605, satin brass 606, bright bronze 611, satin bronze 612, oil-rubbed satin bronze 613, bright nickel 618, satin nickel 619, matte black 622, bright chrome 625, satin chrome 626, satin chrome antimicrobial 626AM, and statuary dark bronze 690. If you are covering an old larger rose footprint, the 3-1/2 inch D rose hides more of the door face than the 3 inch C.
11) Is there an antimicrobial version of the BEST 9K lever for a hospital or school?
Yes, finish 626AM, satin chrome plated with the BEST UltraShield antimicrobial coating that inhibits growth of bacteria and other microbes on the hardware surface. BEST calls it out for healthcare, elderly care, education, transportation, food service and hospitality where cleanliness matters. It is a finish choice, so the lock function and specs are otherwise identical.
12) What makes the BEST 9K worth it over a Grade 2 lever lock on a high traffic door?
It is heavy duty Grade 1 with a corrosion-treated steel chassis, brass latch components, zinc hubs and a hardened steel alloy sleeve. A rose locking pin resists twisting and breaking under attack, and a slotted key release cam keeps key access working even if the lock is damaged. Grade 2 lever locks like the Hager 2580 storeroom or Cal-Royal AG05 are built for lighter cycle counts. On a stairwell, service corridor or entry taking constant traffic or abuse, Grade 1 is the right call.
13) Does the BEST 9K need power or wiring run to the door?
No. The 9K service station lock is purely mechanical, no electronics, no wiring, no power supply. If the opening needs to be released from an access control system, that is a different product entirely, such as the Corbin Russwin CL33903 electrified fail safe cylindrical lever at 12VAC/DC for 1-3/4 to 2 inch doors.
14) Is a classroom function lever an equivalent substitute for the BEST 9K service station lock?
No. The BEST 9K in service station function locks and unlocks the outside lever with an inside push button, so occupants control it from inside the room. A classroom lock has no inside button and is locked and unlocked only by key from the outside. The Dexter C1000 classroom is a Grade 1 clutching keyed classroom lever for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AG03 is a classroom lever in the AG Series with a 6-pin Schlage C keyway and 2-3/4 inch backset. Choose by who needs to control the lock, not by grade alone.
15) What is the difference between the BEST 9K service station lock and an entrance/office lever?
Both use an inside push button, but the BEST 9K in service station function has an inside lever that is always unlocked and cannot be locked, with the outside lever released by the button being out or by key. Entrance/office locks are the adjacent choice for offices where the same button behavior is wanted at Grade 2: the Falcon B511CP6D is a Grade 2 medium duty entry/office cylindrical lever, the Hager 2525 is a Grade 2 commercial entry lever for 1-3/8 inch to 2 inch doors, and the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for 1-3/8 inch to 1-3/4 inch doors. The 9K stays Grade 1 and heavy duty.
16) I need a lever lock on a door thicker than most residential grade sets handle. What works?
The BEST 9K Series lock covers 1-3/4 inch to 2-1/4 inch doors with spacers available for 1-3/8 inch, which is a wider range than most Grade 3 sets: the Kwikset 200BRNL Breton passage is a Grade 3 lever for 1-3/8 inch to 1-3/4 inch, and the Kwikset 300BRNL Breton privacy is a Grade 3 lever over the same 1-3/8 inch to 1-3/4 inch range. Among the heavy duty peers, the Falcon K101 Grade 1 passage matches a 1-3/8 inch to 2-1/4 inch range but is non-keyed.
17) Can an electrified or keypad lever replace the BEST 9K service station lock for access control?
The BEST 9K is a non-electronic mechanical lock with an interchangeable core, so it is rekeyed and master keyed rather than programmed. If the opening is moving to credential or code control, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running 12VAC/DC for 1-3/4 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Those change the door prep and, for the CL33903, require power to the opening, which the 9K does not.
18) How much does the BEST 9K lever project off the door face?
Allow 2-3/4 inch of projection on the door when you check clearance. That matters where a lever sits near a return wall, a door stop, or an adjacent leaf on a pair, since a lever that fouls the jamb on swing is the usual surprise on a retrofit.
19) Is a dummy lever ever the right match to a BEST 9K service station lock on a pair of doors?
On a double door where only the active leaf needs the keyed service station function of the BEST 9K, the inactive leaf takes a dummy trim. The Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever, and Baldwin Estate 5103 half dummy levers with the 5048 rose are offered in left hand and right hand versions. A dummy has no latch and no locking at all, so it is never a substitute for the 9K on a door that must secure.
