BEST 9K37H14CSTK626 – Frequently Asked Questions

1) Will the BEST 9K hotel lock fit my guest room doors, and what door prep does it need?
The 9K hotel function lock goes into a standard ANSI A115.2 cylindrical prep: a 2-1/8 inch cross bore, plus two extra 5/16 inch through-bolt holes at the 12 and 6 o'clock positions. Door thickness range is 1-3/4 to 2-1/4 inches, which covers standard 1-3/4 inch commercial guest room doors and thicker fire-rated leaves. Standard backset is 2-3/4 inches, with 3-3/4 inch and 5 inch backsets also orderable for wider stiles.
2) How does the hotel function actually work on a BEST 9K guest room lock?
Pushing the inside button projects an occupied indicator in the outside lever and blocks all operating keys, so housekeeping and staff keys will not open the door while a guest has it set. The inside lever is always unlocked and cannot be locked, so a guest can always get out. It is a single cylinder keyed lock, key outside only.
3) Which strike do I order with the BEST 9K, and will it work with my existing frame prep?
Two strikes are offered: the STK 2-3/4 inch ANSI strike and the S3 4-7/8 inch ANSI strike. The standard strike is 2-3/4 x 1-1/8 inches with a curved lip and box. Match it to what is already cut into the frame, hollow metal frames are usually prepped for the 4-7/8 inch ANSI strike, and the latch throws 9/16 inch, so the strike lip and box have to be set for that engagement.
4) Can I rekey a BEST 9K lock into my existing master key system?
The 9K is interchangeable core ready, so the core pulls with a control key and drops into whatever masterkeyed system the property already runs. That is the practical difference for a hotel: you rekey a room after a lost key in seconds at the door instead of pulling the lock apart. The lock is keyed, single cylinder, key outside.
5) What is the closest Grade 1 cylindrical lever equivalent to the BEST 9K hotel lock for a guest room door?
Within the heavy-duty cylindrical lever locks, the BEST 9K in the H hotel function is the only one built for the guest-room application: pushing the inside button projects an occupied indicator in the outside lever and blocks all operating keys, while the inside lever stays always unlocked. The Grade 1 cylindrical levers alongside it - the Dexter C1000 Entry/Office, the Dexter C1000 Classroom, and the Corbin Russwin CL3110 passage - carry the same Grade 1 rating but run entry, classroom, and passage functions, none of which produce the occupied indicator or key blocking a hotel door needs. If the door truly needs hotel function, the 9K is the substitution target rather than the thing you substitute away from.
6) The guest room door only needs to latch and never lock - what takes the place of a hotel function lock there?
For a corridor, linen closet, or vestibule door that only needs latching, a passage-function lever is the right call and the keyed hotel function is wasted. The Falcon K101 is a Grade 1 heavy-duty passage cylindrical lock, fire rated, fitting doors 1-3/8 inch to 2-1/4 inch thick. The Falcon T101 is also a Grade 1 heavy-duty passage lever, and the Design Hardware X75 is a Grade 1 passage lever set with a flat lever for 1-3/4 inch doors. All three drop the cylinder entirely, so there is no key to issue or rekey on that opening.
7) Is a privacy lever the same thing as a hotel function lock for a guest room?
No - they behave differently at the door. The BEST 9K hotel function blocks all operating keys when the inside button is pushed, and it is a keyed single-cylinder lock, so staff key control still exists on the opening. A privacy lever such as the Hager 2540 or the Arrow MK02-TA is a bed and bath device with no operating key in normal use. Privacy suits a bathroom or an interior door inside the unit; the guest room entry door is where hotel function belongs.
8) Do I have to order the BEST 9K lock handed for left or right hand doors?
No handing to specify. The 9K is non-handed, so one lock covers both left and right hand guest room doors, which is what you want when you are stocking spares for a property with openings swinging both ways.
9) What lever and rose options do I pick from on the BEST 9K, and can I match the rest of the building?
Three lever styles: Contour with Angle Return, Curved with Return, and Curved without Return. Two rose sizes: C rose at 3 inch convex and D rose at 3-1/2 inch convex. The larger D rose is the one to specify if you are covering scarring from a previous lock. Twelve finishes run from 605 bright brass through 622 matte black, 626 satin chrome and 690 statuary dark bronze.
10) Is there an antimicrobial finish for the BEST 9K in healthcare or senior living rooms?
Order finish 626AM, BEST UltraShield antimicrobial coated satin chrome. It inhibits growth of bacteria and other microbes on the hardware surface, and BEST calls it out for hospital and healthcare, elderly care, education, transportation, food service and hospitality. Same hotel function, same Grade 1 chassis, just the coated finish.
11) Should I use a hotel function lock or a storeroom or classroom lock on my guest rooms?
Hotel function is the right call only where an occupant needs to lock out staff keys from inside, guest rooms, dorm rooms, patient rooms. A storeroom function stays locked outside at all times and any valid key works, which is what you want on mechanical and back-of-house doors, and ZenSupply carries that as the Hager 2580 Grade 2 storeroom lever or the Cal-Royal AG05 Grade 2 storeroom lockset with deadlocking latchbolt. For a classroom door where a teacher keys the outside lever locked, look at the Dexter C1000 classroom function instead. Only the 9K H gives you the occupied indicator and key blocking.
12) What else could I buy if I need a Grade 1 cylindrical lever but not the hotel function?
Staying at Grade 1 cylindrical, the Corbin Russwin CL3110 is a vandal resistant passage lever, fire rated, for 1-3/4 to 2 inch doors. The Falcon K101 is a Grade 1 heavy duty passage lock, fire rated, with a wider 1-3/8 to 2-1/4 inch door range. For an electrified opening on a card access system, the Corbin Russwin CL33903 is a Grade 1 fail safe cylindrical lever at 12VAC/DC. The 9K H is mechanical only, no electrified version.
13) I have wide stile aluminum or thick doors, will a 2-3/4 inch backset 9K reach the latch?
Order the longer backset instead. The 9K is available with 3-3/4 inch and 5 inch backsets alongside the standard 2-3/4 inch, which is what you need when the lock has to sit further off the door edge on a wide stile or a door with a deep rail. Measure from the door edge to the center of the bore hole and match that number to the backset.
14) Can I use a Grade 2 lever on hotel guest rooms instead of a Grade 1?
It depends on how hard the opening gets used. The BEST 9K carries a Grade 1 rating at a heavy duty level. Common Grade 2 cylindrical levers include the Falcon B101 passage and Falcon B511CP6D entry/office, both rated medium duty, along with the Hager 2525 entry and the Accentra 5301LN Augusta passage. A Grade 2 medium-duty lever is a different cycle and strength class than a Grade 1 heavy-duty chassis, and none of those Grade 2 units run hotel function, so on a guest room entry the grade question and the function question have to be answered together.
15) For a back-of-house or storage door in the same hotel, what do you use instead of the hotel function lock?
Storeroom function is the usual choice there: the outside lever stays locked and takes a key every time, which suits housekeeping closets, mechanical rooms, and supply storage. 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 thick, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever for doors 1-3/8 inch to 2 inch. The BEST 9K stays on the guest room doors where the occupied indicator and key blocking are the point.
16) We want keyless entry on the guest rooms - what replaces a keyed cylindrical hotel lock?
Keyless changes the credential rather than the door prep. The Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Emtek Classic keypad leverset is a code-entry lever. Mechanical keypad options include the Lockey 1150, which fits doors 1-1/8 inch to 2 inch, the Lockey 1150S with an adjustable backset, and the Lockey 2835DC double-combination keyless lever for doors 1-3/16 inch to 2 inch. The BEST 9K is a non-electronic keyed lock with an interchangeable core, so it stays on the master key system rather than a code list - that is the real decision between the two paths.
17) The opening needs to unlock on a fire alarm signal - what goes on that door instead?
That is an electrified opening, and a mechanical hotel lock cannot do it. The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock running 12VAC/DC, offered with the NZ lever and D rose, for doors 1-3/4 inch to 2 inch thick. The BEST 9K is a non-electronic lock, so it has no wired release path - use it on the guest room doors and put the electrified lever on the openings tied into access control or alarm release.
18) Our building standard is a Schlage C keyway - does that rule out the BEST 9K?
The BEST 9K is a keyed single-cylinder lock built to take an interchangeable core, so the keying is set by the core you install rather than being fixed to the lock body. If a facility is standardized on a conventional Schlage C cylinder instead, the Cal-Royal AG00 entrance lever and AG03 classroom lever are supplied with a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS asylum lock uses a conventional cylinder in the Schlage C keyway. On Yale hardware, the Accentra 107S is a Schlage cylinder adapter kit. Decide the keyway plan first, then the lock follows it.
19) The door is a patient room or a behavioral health room, not a hotel room - is the hotel function still right?
Not usually. Patient and institutional rooms often call for asylum or institution function, where both levers are keyed and there is no inside button to defeat. The Dexter C1000 Asylum is a Grade 1 lock in the F87 asylum function for doors 1-3/8 inch to 2 inch thick, and the Arrow MK33-BD-CS is a Grade 2 asylum and institution lock at heavy duty level. The 9K hotel function deliberately leaves the inside lever always unlocked so an occupant can always exit, which is the opposite of what a controlled institutional room wants.
20) A knob-style lock is on the door now - can I swap in the BEST 9K, and when would I stay with a knob?
The 9K is a lever lockset, non-handed, on a cylindrical chassis - the same bored family as knob locks like the Arrow HK11 ball knob entrance lock and the Arrow MK02-TA Tudor knob privacy lock for 1-3/4 inch to 2 inch doors. Levers are the usual choice where accessible operation matters on guest room and public doors; a knob is typically kept only on doors where an existing standard calls for it. Confirm the existing bore and backset against the 9K, which is offered in 2-3/4 inch, 3-3/4 inch, and 5 inch backsets.
21) The door has an exit device on it - does a cylindrical hotel lock work there?
No, an exit device opening needs lever trim built for that device rather than a bored lockset. The Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device for doors 1-3/4 inch to 2 inch, and the Imperial USA ED-EL500HD is a heavy duty escutcheon lever trim in entry function. The BEST 9K is a cylindrical lockset that installs in a bored door prep, so it belongs on the guest room doors and not on the stair or corridor doors carrying exit devices.
22) What makes the BEST 9K hotel lock hold up better than a standard commercial leverset?
Heavy duty Grade 1, with latch and chassis components in brass or corrosion-treated steel, zinc hubs, and a hardened steel alloy lever sleeve. The rose locking pin and rose assembly resist torque, which is the attack a lever takes in a corridor, someone hanging on it or twisting it. A hub-mounted torsion spring plus retractor springs is what keeps the lever from sagging after a few hundred thousand guest cycles.
23) What lever do I order for the inactive leaf of a guest room pair, or a closet door that only needs a pull?
A dummy lever is the part for a leaf with no latch. The Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever, the Callan Bentley BN5051 is a Grade 2 dummy lever, and the Baldwin Estate 5103 half dummy comes in left hand and right hand versions on the 5048 rose. Emtek offers dummy pairs in the Arts and Crafts, Hammered, and Cortina levers. None of these operate a latch, so they pair with a functioning 9K on the active leaf rather than replacing it.
24) Can a residential-grade lever stand in for a commercial hotel lock on apartment or extended-stay doors?
They are built to different service expectations. The BEST 9K is a commercial lock at Grade 1 and heavy duty. The Kwikset 200BRNL Breton passage and 300BRNL Breton privacy levers are Grade 3 for doors 1-3/8 inch to 1-3/4 inch, and the Callan Artino and Bennett entrance leversets are Grade 3 as well, with the Cal-Royal AUS00 entrance and office lever also Grade 3. Those suit interior residential doors; a high-cycle unit entry door in a hotel or multi-tenant building is a heavier-traffic opening.
