BEST 9K37AB14LS3626 – Frequently Asked Questions

1) Will the BEST 9K cylindrical lever lock fit a 1-3/4 inch commercial door?
Yes. The 9K lever lock is prepped for doors 1-3/4 inch to 2-1/4 inch thick, so standard 1-3/4 inch commercial doors are right in the middle of the range. Door prep is a 2-1/8 inch diameter bore plus two 5/16 inch through-bolt holes at the 12 and 6 o'clock positions, per ANSI A115.2.
2) Do I need to order the BEST 9K lever lock handed for a left or right hand door?
No handing to specify. The 9K is non-handed, so one part number covers left and right hand openings and you can stock a single lock for a whole building.
3) Does the BEST 9K lever lock come with a core, or do I key it myself?
It ships less core. The 9K takes a small format interchangeable core, so a locksmith drops in your own SFIC to put the lock on an existing master key system, and re-keying later is a core swap rather than a lock teardown.
4) Can the BEST 9K lever lock go on a fire rated door?
Yes. The 9K is UL listed for 3-hour A label single or swinging double doors, which covers most rated stairwell and corridor openings. The lever design and operation also meet ANSI A117.1 section 404.2.6 for accessible operable parts.
5) Will the BEST 9K latch engage my existing strike?
The 9K uses a solid brass latch with a 9/16 inch throw. It is supplied with a 4-7/8 inch ANSI strike (S3) for standard hollow metal frame prep, and the 2-3/4 x 1-1/8 inch curved lip strike with box is the alternative for wood frame or T-strike prep. If your frame already has a 4-7/8 inch ANSI cutout, the S3 drops straight in.
6) What is a Grade 2 alternative to the BEST 9K storeroom lever for a lower-traffic storage room?
The Hager 2580 with Withnell lever is a Grade 2 cylindrical storeroom lock that fits doors 1-3/8 inch to 2 inch thick. The Cal-Royal AG05 is also a Grade 2 storeroom leverset with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch. Both cover the same storeroom function as the BEST 9K, which is rated BHMA Grade 1 and heavy duty with a 2-3/4 inch backset.
7) I need a matching non-keyed lever for the corridor doors next to my BEST 9K storeroom locks. What Grade 1 passage lock should I use?
For Grade 1 passage openings, the Falcon K101 is a heavy duty Grade 1 cylindrical passage lock, fire rated, with a 1-3/8 inch to 2-1/4 inch door thickness range. The Falcon T101 and the Dexter C1000 passage are also Grade 1 passage levers, the Dexter covering 1-3/8 inch to 1-3/4 inch doors. The BEST 9K itself is keyed and single cylinder, so it is not the part for a door that only needs latching.
8) The opening needs classroom function instead of storeroom. What should I order?
The Dexter C1000 classroom lever is a Grade 1 clutching keyed cylindrical lock for doors 1-3/8 inch to 1-3/4 inch, and the C1000 classroom security version adds the second keyed side. Cal-Royal AG03 is a classroom lever in the AG Series with a 2-3/4 inch backset. The BEST 9K described here is a storeroom function lock, so the lever stays locked and is not the right function for a classroom opening.
9) Is a Grade 1 cylindrical lock like the BEST 9K worth it over a Grade 2 lever for a high traffic corridor?
For heavy traffic, yes. The 9K carries a BHMA A156.2 Series 4000 Grade 1 listing and is built with through-bolt mounting studs, a rose locking pin and heavy rose liner to resist someone twisting the lever off. Grade 2 leversets such as the Hager 2580 storeroom or the Cal-Royal AG05 storeroom are cheaper to standardize on for lower-use interior doors, but they are a lighter duty class.
10) What lever and rose do I get on the BEST 9K, and can I get an antimicrobial finish for a hospital?
The configuration is the 14 lever, a curved lever with a return, on the L rose, a 3-1/2 inch convex rose with no ring, in 626 satin chrome. For healthcare, elderly care, food service and similar, the 9K is also offered with the UltraShield antimicrobial coating in finish 626AM, which inhibits bacterial growth on the hardware surface.
11) I need a Grade 1 lever on the same openings but not keyed. What pairs with the BEST 9K?
The 9K here is the keyed cylindrical version. For the non-keyed doors on the same job, Grade 1 passage leversets that match the duty class include the Falcon K101, which covers 1-3/8 to 2-1/4 inch doors and is fire rated, the Corbin Russwin CL3110 vandal resistant passage for 1-3/4 to 2 inch doors, and the Dexter C1000 passage with clutching levers.
12) Is a Kwikset or Baldwin lever an equivalent substitute for the BEST 9K?
No. The Kwikset 200BRNL Breton passage and 300BRNL Breton privacy levers are Grade 3 residential-duty sets for doors 1-3/8 inch to 1-3/4 inch, and the Baldwin Estate 5103 comes in passage, privacy and dummy functions. None of those are keyed storeroom locks. The BEST 9K is a commercial Grade 1 heavy duty keyed cylindrical storeroom lever, so for a commercial storeroom opening a residential passage or privacy set is not a substitute.
13) I need access control on this door instead of a key. What electrified or keypad lever works in place of the BEST 9K?
For an electrified cylindrical opening, the Corbin Russwin CL33903 is a Grade 1 fail safe lever running 12VAC/DC for doors 1-3/4 inch to 2 inch. For standalone keyless entry, the Lockey 2835DC is a double combination mechanical keyless lever lock for doors 1 3/16 inch to 2 inch, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. The BEST 9K is a non-electronic mechanical lock with an SFIC less core prep.
14) What is the difference between the BEST 9K storeroom lever and an entrance/office function lever like the Falcon B511 or Cal-Royal AUS00?
The Falcon B511CP6D is a Grade 2 medium duty cylindrical lever with entry/office function, and the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a forged solid brass body for 1-3/8 inch to 1-3/4 inch doors. Entrance/office function lets the inside lock the outside lever with a button or turn. The BEST 9K described here carries storeroom function, where the outside lever is always locked and only the key retracts the latch, on a Grade 1 heavy duty chassis.
15) I need a utility or institutional function lock rather than storeroom. What are the options?
The Dexter C1000 asylum lock is a Grade 1 F87 asylum/institution/utility cylindrical lock for 1-3/8 inch to 2 inch doors, keyed both sides. The Arrow MK33-BD-CS is a heavy duty asylum/institution lock with a ball knob and a conventional Schlage C keyway cylinder. Those keep the lock keyed from both sides, where the BEST 9K storeroom function is keyed on one side only as a single cylinder.
16) Does the BEST 9K lever lock need power or wiring?
No. The 9K is a mechanical cylindrical lock with no electrified components, so there is no transfer hinge, power supply or door loop to run. If the opening needs electric access control, a fail safe electrified lever such as the Corbin Russwin CL33903 at 12VAC/DC is the direction to go instead.
17) Can I use a dummy lever to match the BEST 9K on a door that does not need to latch?
For an inactive leaf or pull-only door, the Accentra 455LN Augusta is a heavy duty Grade 1 single dummy cylindrical lever, which keeps the commercial grade consistent with a Grade 1 keyed opening. Baldwin Estate 5103 half dummy levers are offered in left and right hand versions. The BEST 9K is a keyed storeroom lock with a solid brass latch and is not offered as a trim-only dummy.
