BEST 9K30P15CSTK690 – Frequently Asked Questions

1) How does the patio function on the BEST 9K lock actually work day to day?
The 9K patio (P) function is a push-button privacy lock. Rotating the inside lever always retracts the latch, and the inside lever cannot be locked. The outside lever works only when the inside push button is out; pushing the button locks the outside lever. There is no key and no cylinder, so once someone inside pushes the button, the door can only be opened from the outside after the button is released from the inside.
2) Can I use the BEST 9K patio lock on a 1-3/8 inch door, or is there a privacy lever that will fit one?
No, the 9K patio lock starts at 1-3/4 inches, so a 1-3/8 inch leaf is outside its range. For a thinner door, the Hager 2540 privacy lever covers 1-3/8 to 2 inches, and the Arrow MK02-TA privacy lock covers 1-3/4 to 2 inches if the door is at least 1-3/4. On the lighter residential side, the Kwikset 300BRNL Breton privacy lever handles 1-3/8 to 1-3/4 inch doors at Grade 3.
3) What backset does the BEST 9K patio lever come in, and will it work on a wide-stile or thicker door?
Three backsets are offered: 2-3/4 inches standard, plus 3-3/4 inch and 5 inch options for wide-stile doors or unusual door preps. Standard bored-door prep in the US is 2-3/4 inch on commercial openings, so that is the one to pick unless your existing cross-bore says otherwise. Measure from the door edge to the center of the 2-1/8 inch bore before ordering.
4) Will the BEST 9K patio lock latch into the strike already in my frame?
The latch has a 9/16 inch throw and the standard strike supplied is a 2-3/4 x 1-1/8 inch curved lip with box. Two strike choices are offered: the STK 2-3/4 inch ANSI strike and the S3 4-7/8 inch ANSI strike. If your frame is prepped for a full 4-7/8 inch ANSI strike, order the S3 so you are not filling a cutout; if it is a T-strike prep, the STK matches.
5) Is the BEST 9K patio lock rated for heavy traffic, and what ANSI function code is it?
It carries BHMA Grade 1 and is classified heavy duty, which is the top commercial tier for cycle life and strength. The function is ANSI/BHMA F77, the patio/privacy designation. For a facilities spec sheet that calls out F77 Grade 1 bored lever, this matches.
6) What is a Grade 1 alternative to the BEST 9K patio lock if the door only needs to latch and never lock?
The BEST 9K P patio function locks the outside lever with an inside push button while the inside lever always stays unlocked. If the opening needs no locking at all, a passage lockset is the match: the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet cylindrical lever lock. Both drop the push button entirely, so the latch simply retracts from either side.
7) Which non-keyed lever locks look like a substitute for the BEST 9K patio lock but will not work on a functioning door?
Dummy levers are the common mix-up. The Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever, and the Baldwin Estate 5103 half dummy comes in left and right hand versions. All are non-keyed like the BEST 9K P, but a dummy lever is surface mounted trim with no latch and no push button, so it cannot secure or latch an active opening the way the patio function does.
8) My BEST 9K door is thinner than 1-3/4 inch - what lever lock fits it instead?
The BEST 9K P patio lock is built for 1-3/4 inch through 2-1/4 inch doors. For thinner leaves, the Falcon K101 Grade 1 passage lock covers 1-3/8 inch to 2-1/4 inch, the Dexter C1000 asylum lock covers 1-3/8 inch to 2 inch, and the Hager 2510 Grade 2 passage lever covers 1-3/8 inch to 2 inch. Confirm the function you need separately, since these are passage and asylum rather than patio.
9) What should I use instead of the BEST 9K patio lock on a behavioral health or utility door?
Patio function leaves the inside lever always unlocked, which is not what those rooms call for. An asylum or institution function is the usual answer: the Dexter C1000 Grade 1 asylum lock (F87) fits 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty asylum cylindrical lock with a ball knob and conventional Schlage C keyway cylinder. Those functions key both sides rather than relying on an inside button.
10) Do I have to specify handing for the BEST 9K patio lever?
No. The 9K patio lever is non-handed, so one part number covers left and right hand openings and you do not need to determine swing before ordering. That also means a single SKU can be stocked for an entire building's restroom or patio doors.
11) What lever, rose and finish choices do I have to pick when ordering a BEST 9K patio lock?
Four things get specified beyond backset and strike: lever style (Contour with angle return, Curved with return, or Curved without return), rose style (C rose 3 inch convex or D rose 3-1/2 inch convex), and finish. Finishes run 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil-rubbed bronze, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 626AM satin chrome antimicrobial, and 690 statuary dark bronze. The larger D rose is the one to pick when you need to cover marks or wear from previously removed trim.
12) What door prep does the BEST 9K lever need beyond the standard bore?
Prep follows ANSI A115.2 bored door preparation, plus two extra 5/16 inch diameter holes at the 12 o'clock and 6 o'clock positions for the through-bolt mounting studs. Those through-bolts are what give the lock its torque resistance, so they are not optional on a retrofit into an existing 161 prep.
13) For a restroom or bedroom door, is the BEST 9K patio lock the right function or should I use a privacy set?
The BEST 9K P is a patio/privacy function: the inside push button locks the outside lever and the inside lever cannot be locked. Many spec writers want a dedicated privacy/bed/bath set instead, such as the Hager 2540 Grade 2 privacy cylindrical lock with Withnell lever or the Arrow MK02-TA Grade 2 privacy cylindrical lock with a Tudor knob. The Arrow uses a knob rather than a lever, which matters where ADA lever operation is required.
14) I need a keyed lock on the same door style as the BEST 9K patio lock - what changes?
The BEST 9K P is non-keyed, so it has no cylinder at all. For a keyed cylindrical lever on comparable commercial doors, the Hager 2580 is a Grade 2 storeroom cylindrical lock with Withnell lever, the Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt, and the Dexter C1000 classroom lever is a Grade 1 keyed clutching cylindrical lock. Keyed functions require you to specify keyway and keying, which the non-keyed patio lock does not.
15) Is there a lighter-duty lever lock than the BEST 9K patio lock for low traffic interior doors?
The BEST 9K P is Grade 1 heavy duty and built for commercial traffic. Where the cycle demand is lower, Grade 2 cylindrical levers cover the same interior openings: the Falcon B101 is a Grade 2 medium duty passage lever, the Accentra 5301LN Augusta is a Grade 2 passage/closet cylindrical lever, and the Design Hardware J75 is a Grade 2 passage leverset with a flat lever for 1-3/4 inch doors. Note these are passage functions, so none of them offer the inside push button locking of the patio function.
16) Can I get keyless code entry on the same opening instead of the BEST 9K push button patio lock?
The BEST 9K P is a mechanical, non-electronic lock controlled by an inside push button. If you want code entry on that door, the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination and passage function for 1-1/8 inch to 2 inch doors, the Lockey 2835DC is a double combination keyless lever lock with passage function for 1-3/16 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. These control access from the outside by code rather than by an inside button.
17) For a fire-rated opening, what Grade 1 cylindrical lever compares to the BEST 9K?
Among Grade 1 cylindrical levers, the Corbin Russwin CL3110 passage/closet lock and the Falcon K101 passage lock both carry a fire rating in their specs. Both are non-keyed like the BEST 9K P, but they are passage function, so if the opening also needs the inside push button locking the BEST 9K P provides, verify the fire label requirements for that function with the door manufacturer.
18) Why would I spec 626AM antimicrobial over standard 626 satin chrome?
626AM is the antimicrobial version of the satin chrome finish and it looks the same on the door as standard 626, so you can mix the two in a building without a visual mismatch. Healthcare and food-service touch points are where facilities typically call for it; back-of-house doors in the same job can stay standard 626.
19) Is the BEST 9K patio lever electronic or can it be wired for access control?
The 9K P is a mechanical, non-electronic lock with no cylinder. If the opening needs to be controlled electrically, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running 12VAC/DC for 1-3/4 to 2 inch doors. For keypad entry without wiring, the Lockey 1150 mechanical keypad lever set covers 1-1/8 to 2 inch doors.
20) What is the BEST 9K lever made of, and will it sag over time in a high traffic building?
Critical latch and chassis parts are brass or corrosion-treated steel, with zinc hubs and a hardened steel alloy sleeve. Lever sag is addressed with a hub-mounted torsion spring plus heavy retractor springs, and the rose uses a locking pin to resist twisting or prying. That construction plus the Grade 1 heavy duty rating is what puts it on school, hospital and office restroom doors.
21) I need the same 9K lever look on an inactive leaf - what do I order?
The BEST 9K P is an operating patio lock with a latch and inside push button, so it is not the part for an inactive leaf. Dummy trim covers that: the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever, the Emtek Arts and Crafts and Cortina leversets come as dummy pairs, and the Callan Bentley is a Grade 2 dummy lever. Pair the dummy trim on the inactive leaf with your working lock on the active one.
22) What is the closest Grade 1 passage lever to the BEST 9K if I want a clutching lever?
The BEST 9K P uses a hub-mounted torsion spring and strong retractor springs to prevent lever sag rather than a clutch. For a clutching Grade 1 lever, the Dexter C1000 passage lock is a non-keyed clutching cylindrical lever, and the Falcon T101 is a Grade 1 heavy duty passage lever using pressure release technology. Both are passage function, so neither offers the patio push button.
