BEST 7KC37AB15DS3626 – Frequently Asked Questions

1) How does the entrance function on the BEST 7KC lever actually work day to day?
Entrance function, single cylinder: the outside lever is locked or unlocked from the inside, and the key retracts the latch from outside when it is locked. The inside lever always retracts the latch for free egress. That is the pattern for a tenant suite door, an office, or a back-of-house entry where staff secure it from within and a keyholder gets in from the corridor. If you need a door that stays locked outside at all times and cannot be left unlocked by an occupant, a storeroom function such as the Hager 2580 with the Withnell lever is the right call instead.
2) Can I put the BEST 7KC lever on a fire rated door?
UL listed for 3-hour A label single doors up to 4 feet by 8 feet. That covers most rated stair, corridor, and tenant entry doors in a commercial building. Pairs and oversized leaves fall outside that listing.
3) Does the BEST 7KC lever take a BEST interchangeable core, and can it go on our existing master key system?
It takes the BEST 7-pin interchangeable core in solid brass, so a locksmith with a control key swaps the core in seconds and the lock drops onto an existing BEST small format masterkey system. That is the reason to standardize on 7KC across a facility: rekeying a tenant turnover is a core pull, not a lock removal.
4) Which strike do I order with the BEST 7KC, ANSI or standard?
Two choices at order time: the S3 ANSI strike, which is the 4-7/8 inch full lip plate that matches ANSI prepped hollow metal frames, or the STK standard strike for a smaller conventional frame prep. Pick the one that matches the cutout already in your frame; putting an ANSI strike on a frame prepped for a standard one means new frame work.
5) Is the BEST 7KC lever ADA compliant for a public building?
The lever design meets ANSI A117.1 section 404.2.6 and the Illinois Accessibility Standard for accessible door hardware, which is the operable-without-tight-grasping requirement that rules out knobs on accessible routes. All three lever styles offered (14 curved with return, 15 contour with angle return, 16 curved without return) are lever trim, so the choice is aesthetic, not a compliance decision.
6) Is a Grade 2 lever like the BEST 7KC enough for a school or hospital corridor, or should I step up to Grade 1?
Grade 2, medium duty, meeting BHMA A156.2 Series 4000. That is sized for moderate traffic: offices, tenant suites, back-of-house, multi-family unit doors. For a high-cycle corridor, a classroom door, or anywhere the lever gets abused, a Grade 1 heavy duty cylindrical is the better spend. The Falcon K101 in the K Series and the Corbin Russwin CL3100 Series are Grade 1 cylindrical options; the Dexter C1000 Series covers Grade 1 in classroom and classroom security functions.
7) I need a keyed entry lever but not the BEST interchangeable core system. What else is there?
If you are not on a BEST SFIC keyway, several keyed entry levers avoid it. The Hager 2525 is a Grade 2 commercial cylindrical entry lock for 1-3/8 to 2 inch doors, the same thickness range. The Cal-Royal AG00 entrance lever comes with a 6-pin Schlage C keyway keyed different at a 2-3/8 inch backset. The Falcon B511CP6D is Grade 2 medium duty in entry/office function. For heavier traffic, the Dexter C1000 entry/office is Grade 1 for 1-3/8 to 1-3/4 inch doors.
8) What do I have to specify to order a BEST 7KC lever lock correctly?
Four choices settle the order: backset (2-3/8 or 2-3/4 inch), lever style (14, 15, or 16), finish (605, 606, 612, 613, 625, or 626), and strike (S3 ANSI or STK standard). Handing is not one of them, since the lock is non-handed. Get the backset and strike right against the existing door and frame prep first, then pick lever and finish to match the rest of the building.
9) What is the closest equivalent to a BEST 7KC entrance lever from another manufacturer?
The Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle, and it fits doors 1-3/8 inch to 2 inch thick - the same thickness range the BEST 7KC entrance lever covers. Both are keyed cylindrical leversets in the entrance function, so the swap is a like-for-like on the opening. The difference that matters for keying is the cylinder: the 7KC uses the BEST interchangeable core with a 7-pin solid brass core, so if the building is already on a BEST IC master key system, moving that door to the Hager takes it off that system.
10) I need a keyed lever for a storeroom door, not an office door - what do I use instead of the 7KC entrance function?
Entrance function on the 7KC means the outside lever can be left unlocked for business hours. A storeroom door should stay locked at all times, so use a storeroom function instead: the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever and fits 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch. Both hold the outside lever locked with entry by key only.
11) My opening is high traffic - what Grade 1 lever should I specify instead of a Grade 2 medium duty lock?
The 7KC is Grade 2 medium duty, which suits moderate traffic. Where the cycle count justifies Grade 1, the Dexter C1000 Series entry/office lever is a Grade 1 keyed clutching cylindrical lock for doors 1-3/8 inch to 1-3/4 inch and holds the same entry/office intent. On non-keyed openings in the same corridor, the Falcon K101 is a Grade 1 heavy duty non-handed passage lock, fire rated, for doors 1-3/8 inch to 2-1/4 inch. Note the Dexter's narrower door thickness range if any of your doors run to 2 inch.
12) Is a Cal-Royal AUS00 entrance lever the same thing as a BEST 7KC entrance lever?
They serve the same opening but not the same specification. The Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for doors 1-3/8 inch to 1-3/4 inch; the BEST 7KC is Grade 2 for doors 1 3/8 inch to 2 inch. If the drawing calls out ANSI Grade 2 or the door is thicker than 1-3/4 inch, the AUS00 will not satisfy it. The Cal-Royal AG00 entrance lever is Grade 2 with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset, so it matches on grade but is keyed on a Schlage C keyway rather than the BEST interchangeable core.
13) What should I use for a classroom door instead of an entrance function lever?
Entrance function is not a classroom function - a classroom lock is keyed from the outside to lock and unlock the outside lever, with the inside lever always free. The Cal-Royal AG03 is a classroom lever, Grade 2, with a 6-pin Schlage C keyway keyed different on a 2-3/4 inch backset, and the Dexter C1000 classroom lever is Grade 1, clutching and keyed, for doors 1-3/8 inch to 1-3/4 inch. Where the room needs lockdown from inside, the Dexter C1000 classroom security version is the Grade 1 option in the same range.
14) My doors are 1-3/4 inch to 2 inch thick - which comparable levers cover that and which do not?
The BEST 7KC covers 1 3/8 inch to 2 inch, so it spans the whole range. Among peers, the Hager 2525 entry lock and Hager 2510 passage lever cover 1-3/8 inch to 2 inch, and the Corbin Russwin CL3110 vandal resistant Grade 1 passage lever covers 1-3/4 inch to 2 inch. Levers that stop short include the Arrow HK11 entrance lock and the Cal-Royal AG05 storeroom lever, both 1-3/8 inch to 1-3/4 inch, and the Design Hardware J75 passage lever, which is 1-3/4 inch only.
15) Do I need to specify handing for the BEST 7KC lever lock?
No handing to specify. The 7KC is non-handed, so one lock serves a left- or right-hand door and you can stock a single part number across a building instead of splitting inventory. Handing matters only for the lever style you pick visually, not for how the lock is ordered.
16) What finishes does the BEST 7KC lever come in, and can I match the other doors in the building?
Six BHMA finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, and 626 satin chrome. 626 satin chrome is the commercial default you will find on most existing openings, and 613 is the dark oil-rubbed look. Match the BHMA number rather than the name, since brands describe the same number differently.
17) Is the BEST 7KC lever secure enough that someone cannot just twist it off the door?
Through-bolt mounting studs tie the two sides together for torque resistance, so wrenching the lever does not spin the assembly off the door. There is no exposed keeper hole on the keyed lever, and the lever cannot be pulled until the core has been removed with a control key, which shuts down the usual quick-attack routes on a cylindrical lock. Internal steel is corrosion treated with zinc dichromate for normal atmospheric conditions.
18) Can I use the BEST 7KC entrance lock on interior doors that do not need a key?
No. The 7KC entrance version is keyed, single cylinder, so you are paying for a cylinder on a hall or closet door that does not need one. Use a passage lever there: the Falcon B101 is Grade 2 medium duty non-handed passage, and the Hager 2510 with the Withnell lever is Grade 2 passage covering 1-3/8 to 2 inch doors. For bedroom or restroom doors, privacy function is the one to order, such as the Hager 2540.
19) The door needs to release on a fire alarm - can a 7KC lever do that?
No, the 7KC is a mechanical lock with no electrical option. For an access-controlled opening that unlocks when power drops, use an electrified cylindrical lever such as the Corbin Russwin CL33903, a Grade 1 fail safe electrified lever running 12VAC/DC for doors 1-3/4 inch to 2 inch, available with the NZ lever and D rose. It requires power transfer to the door, which a mechanical lever does not.
20) The door does not need a key at all - what is the non-keyed version of a Grade 2 commercial lever like the 7KC?
For a corridor, hall, or closet door that only needs latching, a passage lever carries no cylinder. The Falcon B101 is a Grade 2 medium duty cylindrical passage lever with a non-handed design, matching the 7KC on both Grade 2 and medium duty. The Hager 2510 is a Grade 2 passage cylindrical lever with the Withnell design for doors 1-3/8 inch to 2 inch, and the Accentra 5301LN Augusta is a Grade 2 passage/closet cylindrical lever in the 5300 Series. None of these lock, so they are only right where the door never has to secure.
21) What looks like a substitute for a 7KC entrance lever but will not actually secure the door?
Dummy trim is the usual mistake. The Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever and the Callan Bentley BN5051 is a Grade 2 dummy lever - both are pull trim with no latch and no cylinder, so they cannot replace a keyed entrance lock. The Emtek Arts and Crafts and Cortina dummy pairs are the same story. Baldwin Estate 5103 comes in dummy, passage, and privacy versions, none of which is keyed; only a keyed entrance lock does the job the 7KC does.
22) I want to stop issuing keys for this door - what keyless lever replaces a keyed entrance lock?
A mechanical or electronic keypad leverset removes the key from the opening entirely. The Lockey 1150S is a heavy duty mechanical keypad lever set with an adjustable backset for doors 1-1/8 inch to 2 inch, and the Lockey 2835DC is a double combination mechanical keyless lever lock in passage function for doors 1 3/16 inch to 2 inch. The Delaney LP250 is a Grade 2 electronic keypad leverlock, matching the 7KC on grade. The trade is key management: the 7KC's BEST interchangeable core lets you rekey the door in seconds and keep it on a master key system, which a combination lock does not do.
23) Can I put a Kwikset Breton or Delta lever on a commercial corridor door instead of a BEST 7KC?
They are built to a different standard. The Kwikset 200BRNL Breton passage lever and the 300BRNL Breton privacy lever are Grade 3 for doors 1-3/8 inch to 1-3/4 inch, and the 200DL Delta is a passage lock for interior hall and closet use. The BEST 7KC is a Grade 2 commercial lock. Where a specification calls for Grade 2 commercial hardware, or the opening needs a key, a Grade 3 residential passage or privacy lever does not meet it.
24) Is there a knob version of a Grade 2 entrance cylindrical lock, for an opening where a lever will not work?
The BEST 7KC is a lever, non-handed. Where a knob is wanted instead, the Arrow HK11 is a Grade 2 turn-pushbutton entrance cylindrical lock with a ball knob and a conventional cylinder for doors 1-3/8 inch to 1-3/4 inch. Keep in mind the 7KC lever design meets ANSI A117.1 section 404.2.6 for accessible operation, so on an opening subject to accessibility requirements the lever is the form to keep.
25) What is the difference between the BEST 7KC entrance function and a Falcon B511 entry/office lever?
Both are Grade 2 medium duty cylindrical levers for the same class of opening: the Falcon B511CP6D is an entry/office function Grade 2 medium duty lever, and the BEST 7KC is entrance function, Grade 2, medium duty, non-handed, for doors 1 3/8 inch to 2 inch with backsets of 2 3/8, 2 3/4, 3 3/4, and 5 inch. The distinguishing feature is the cylinder: the 7KC takes the BEST interchangeable core, so a locksmith can rekey the door by pulling the core with a control key.
26) I need a lever for a bathroom door on the same job - what pairs with a 7KC entrance lock?
A bathroom door takes a privacy function, which locks from inside with a thumbturn and has no key. The Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever for doors 1-3/8 inch to 2 inch, which keeps the same Grade 2 level and door thickness range as the 7KC entrance lever elsewhere in the building. The Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed and fire rated, if a knob is acceptable on that opening.
27) The opening takes abuse - is there a vandal resistant lever to specify instead?
The Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever lock, fire rated, for doors 1-3/4 inch to 2 inch, in passage/closet function. Because it is non-keyed it only substitutes where the door does not need to secure; on a keyed opening the BEST 7KC brings its own hardening through through-bolt mounting studs for torque resistance, no exposed keeper hole on keyed levers, and a lever that comes off only after the core is removed.
