BEST 9K30N15CS3626 – Frequently Asked Questions

1) Does a BEST 9K passage lock need to be ordered left hand or right hand?
No handing to specify. The 9K passage lever is non-handed, so one part number works on a left or right swinging door and you can stock a single item across a building. That matters when you are buying a pallet of passage sets for a corridor refit and do not want half of them landing on the wrong doors.
2) Will a 9K passage lever latch into the strike that is already in my frame?
The standard latch throws 9/16 inch and the lock ships against a 2-3/4 inch by 1-1/8 inch strike with a curved lip and box. If your existing frame has a full 4-7/8 inch ANSI strike prep, order the S3 strike option instead of the STK 2-3/4 inch ANSI strike, and the lock drops into the existing cutout without patching the frame. Both strike choices are orderable on the 9K.
3) What backset do I need for a BEST 9K cylindrical lever, and can it do a wide stile or a thicker door edge?
Standard is 2-3/4 inch backset, which is the usual commercial bored prep. The 9K also comes in 3-3/4 inch and 5 inch backsets for doors where the bore sits further back from the edge, such as wide stile aluminum or heavy rail openings. Pick the backset before anything else, since it decides whether the chassis reaches the door edge at all.
4) Can a BEST 9K passage lock be locked, or does it always stay free?
Never locks. The latch retracts by turning either the inside or the outside lever, and both levers stay unlocked at all times, with no keyway, no button and no thumbturn. Use it on corridors, hall doors and closets. If you need the room to secure, this is the wrong function and you want a keyed or privacy function instead.
5) What do I have to specify when ordering a BEST 9K passage lever?
Five choices decide the part: backset (2-3/4, 3-3/4 or 5 inch), 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), strike (S3 4-7/8 inch ANSI or STK 2-3/4 inch ANSI) and finish. Twelve finishes are offered, from 605 bright brass through 626 satin chrome to 690 statuary dark bronze. The larger D rose is the one to pick when you are covering an old prep or a scarred door face.
6) What door prep does a BEST 9K cylindrical lock need?
Standard bored prep: a 2-1/8 inch hole in the door face takes the 2-1/16 inch diameter chassis, plus two extra 5/16 inch diameter holes at the 12 and 6 o'clock positions for the through-bolt studs. Those through-bolts are what give the rose its torque resistance, so they are not optional on a commercial install. Confirm the backset of the existing bore matches the backset you order.
7) The door is only 1-3/8 inch thick. What Grade 1 lever works there instead of the BEST 9K?
The BEST 9K N is built for doors 1-3/4 inch through 2-1/4 inch, so a 1-3/8 inch leaf needs a different chassis. The Falcon K101 is a Grade 1 heavy duty passage lever covering 1-3/8 inch to 2-1/4 inch and is the direct answer when the opening is thin and the function is still passage. If the same thin door needs a keyed function, the Dexter C1000 series covers 1-3/8 inch to 1-3/4 inch in Grade 1 with entry/office, classroom, and classroom security functions, and the Dexter C1000 asylum version covers 1-3/8 inch to 2 inch.
8) What is the closest Grade 1 cylindrical passage lever to the BEST 9K N passage lock?
The Falcon K101 is the nearest straight equivalent. Both are Grade 1 cylindrical passage levers rated heavy duty, non-keyed, and non-handed, so either fills the same hall, closet, or corridor opening where the latch is retracted by turning either lever and nothing ever locks. The K101 covers doors from 1-3/8 inch to 2-1/4 inch and carries a fire rating; the BEST 9K N covers 1-3/4 inch to 2-1/4 inch and ships with a 2-3/4 inch by 1-1/8 inch curved lip strike and box as standard. The other Grade 1 passage lever equivalents are the Falcon T101 with pressure release technology and the Corbin Russwin CL3110, a vandal resistant design for 1-3/4 inch to 2 inch doors.
9) Is there a lighter duty passage lever for offices and interior doors that do not see heavy traffic?
Yes. The Falcon B101 is a Grade 2 cylindrical passage lever with a non-handed design, rated medium duty rather than heavy duty, and it serves the same hall and closet function. Other Grade 2 passage levers include the Accentra 5301LN Augusta, the Accentra 4601LN with Augusta trim, the Arrow GL01 with a Sierra lever for 1-3/4 inch to 2 inch doors, the Hager 2510 with the Withnell lever for 1-3/8 inch to 2 inch doors, and the Design Hardware J75 with a flat lever for 1-3/4 inch doors. The BEST 9K N is Grade 1 and heavy duty, which is the specification to hold when a facility standard or a drawing calls for Grade 1.
10) I need the same lever look but the door has to lock. What do I order?
The BEST 9K N is passage only, with both levers always unlocked and no way to lock them, so a lockable opening needs a different function. For a keyed Grade 1 chassis, the Dexter C1000 series covers entry/office, classroom, and classroom security functions. For Grade 2, the Hager 2580 is a storeroom lever with the Withnell trim, the Hager 2525 is a commercial entry lever, and the Cal-Royal AG05 is a storeroom lever with a deadlocking latchbolt. For a privacy bath or bedroom door, the Baldwin Estate 5103 privacy lever and the Kwikset 300BRNL Breton privacy lever both cover that function.
11) Is a Grade 1 passage lever worth it over a Grade 2 for a school or hospital corridor?
The 9K is BHMA Grade 1 and heavy duty, with the chassis and latch built from brass or corrosion-treated steel, and it carries the F75 ANSI/BHMA function designation for passage. On a high-cycle corridor or classroom door that is the difference that keeps the lever from sagging. If the opening is light traffic, a Grade 2 passage set like the Falcon B101 or the Hager 2510 covers the same function at a lower duty level.
12) Is there an antimicrobial version of the BEST 9K lever for a healthcare facility?
Yes, finish 626AM is satin chrome with UltraShield antimicrobial coating that inhibits growth of bacteria and other microbes on the hardware surface. It is the pick for healthcare, elderly care, education, transportation, food service and hospitality doors. Ordering it is just a finish selection, so the lever, rose and backset choices stay the same as the plain 626 satin chrome.
13) Can I standardize a whole building on BEST 9K levers if some doors need to lock?
The passage version cannot be locked, but it shares the 9K chassis platform, lever styles, rose sizes and finishes with the keyed 9K functions, so you can run the same lever look across passage, office and storeroom doors and only change function. Match the lever style, rose and finish code across the order and the doors read as one set even though the functions differ.
14) Can a dummy lever be used in place of the BEST 9K passage lock?
No. A dummy lever is trim only and does not operate a latch, while the BEST 9K N retracts a latch with a 9/16 inch throw when either lever is turned. Dummy trim suits an inactive leaf or a pull-only door: the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever, the Callan Bentley is a Grade 2 dummy lever, and the Emtek Arts and Crafts and Cortina dummy pairs cover both faces. If the door has to latch closed, the passage chassis is the correct part.
15) Is a keypad lever lock an alternative to the BEST 9K passage lock?
They solve different problems. The BEST 9K N is a non-electronic mechanical passage lock that never restricts entry. A keypad lever restricts entry by code: the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in a passage function for 1-1/8 inch to 2 inch doors, the Lockey 2835DC is a double combination keyless lever for 1 3/16 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Choose a keypad only when the opening needs credentialed access; for a door that should always open freely, the mechanical passage chassis is the right part.
16) What passage lever should I use on interior residential doors in an apartment turn?
For unit interiors where commercial Grade 1 is more chassis than the door needs, the Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors, the Kwikset 200DL Delta is a passage lever for interior hall and closet doors with a reversible adjustable 6AL latch and RCS strike, and the Callan Asheville is a Grade 3 passage leverset in satin nickel. Bravura offers Grade 2 passage leversets in the Atlanta, Orlando, and Miramar round trim styles and the Tampa square trim style. The BEST 9K N is the Grade 1 commercial heavy duty option to standardize on for corridor and common area doors in the same building.
17) How does the Design Hardware X75 compare with the BEST 9K passage lock?
Both are Grade 1 passage lever locksets. The Design Hardware X75 has a flat lever and is specified for a 1-3/4 inch door; the BEST 9K N covers 1-3/4 inch through 2-1/4 inch and is offered in Contour with Angle Return, Curved with Return, and Curved without Return lever styles on a 3 inch convex C rose or a 3-1/2 inch convex D rose. The Design Hardware J75 is the Grade 2 counterpart in the same flat lever passage design.
18) Is a knob lock an acceptable substitute for the BEST 9K lever?
Only where a lever is not required. The BEST 9K N uses a lever handle, which is what ADA-conscious specifications call for on accessible routes. The knob options serve other functions rather than passage in any case: the Arrow MK02-TA is a Grade 1 privacy lock with a Tudor knob and a fire rating, the Arrow MK33-BD-CS is a Grade 2 asylum lock with a ball knob in the Schlage C keyway, and the Arrow HK11-BB is a turn-pushbutton entrance lock with a ball knob for 1-3/8 inch to 1-3/4 inch doors. None of them replaces a passage lever on an accessible door.
19) Which passage lever handles a wider backset without a special order?
The BEST 9K N is offered in 2-3/4 inch, 3-3/4 inch, and 5 inch backsets, with 2-3/4 inch standard, and in both the 2-3/4 inch STK ANSI strike and the 4-7/8 inch S3 ANSI strike. That covers wide-stile and unusual door preps that a fixed-backset chassis will not reach. Among the Grade 2 alternatives, the Cal-Royal AG series is built around a 2-3/4 inch backset on the AG03 classroom lever and a 2-3/8 inch backset on the AG00 entrance lever, so verify the existing bore before cross-shopping.
20) For a healthcare corridor, what is the antimicrobial option and is there a peer that matches it?
The BEST 9K N is available in 626AM satin chrome with UltraShield antimicrobial protected coating, which inhibits bacteria and microbe growth on the hardware surface and is aimed at healthcare, elderly care, education, food service, and hospitality. Among the Grade 1 passage peers, the Falcon K101 and the Corbin Russwin CL3110 match on grade and function but the antimicrobial coating is what distinguishes the 9K on an infection-control specification. The 9K N also comes in 605 bright brass, 606 satin brass, 612 satin bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, and 690 statuary dark bronze among others.
21) I need an electrified lever on the same door type. What replaces a passage function there?
A passage lock has no electrified option because it never locks. For access control on a cylindrical chassis, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified lever at 12VAC/DC for 1-3/4 inch to 2 inch doors, offered with an NZ lever on a D rose. The BEST 9K N is a mechanical, non-electronic passage lock, so pair it with openings that are meant to stay free-swinging and put the electrified chassis on the doors that need to be released or secured remotely.
22) Is the BEST 9K passage lever electrified or does it need power?
Purely mechanical, no power and no wiring to the door. If the opening needs to release on an access control signal, look at an electrified cylindrical lever such as the Corbin Russwin CL33903 fail safe at 12VAC/DC, which suits 1-3/4 to 2 inch doors.
23) Which lever style and rose should I pick on a 9K for an accessible corridor door?
Lever choices are Contour with Angle Return, Curved with Return, and Curved without Return. The two return styles turn the lever end back toward the door, which is what keeps clothing and equipment carts from catching on the tip in a busy corridor. Rose is either the 3 inch convex C rose or the 3-1/2 inch convex D rose; the D rose covers more of the door face if you are replacing older trim.
