BEST 7KC37D15DS3626 – Frequently Asked Questions

1) Will the BEST 7KC storeroom lever work on a 1-3/8 inch door, or does it need a 1-3/4 inch door?
Both work. The 7KC cylindrical lever lock covers door thicknesses from 1-3/8 inch through 2 inches, so it drops onto older 1-3/8 inch interior doors as well as standard 1-3/4 inch commercial leaves without a special order. The door needs a 2-1/8 inch bore for the lock housing and a 1 inch cross bore for the latch tube.
2) What backset do I order for a BEST 7KC lever lock, and does it fit a 2-3/8 inch prep?
Order the 7KC in either a 2-3/8 inch or a 2-3/4 inch backset. Those are the two standard bored-lock backsets, so an existing prep almost always takes one or the other. Measure from the door edge to the center of the 2-1/8 inch bore and pick the matching one; the wrong backset will not let the latch reach the strike.
3) What does storeroom function mean on a BEST 7KC lock, and is it right for a supply room or mechanical closet?
Storeroom function is exactly the right choice there. The outside lever on the 7KC stays locked at all times and is retracted only by the key; the inside lever always turns free for egress. Nobody can leave the door unlocked by mistake, which is why it is the standard pick for storage rooms, mechanical and electrical closets, and IT rooms. If you want staff to be able to unlock the door and leave it unlocked during the day, storeroom is the wrong function and you want an entrance/office lock instead.
4) Can I key a BEST 7KC lock into my existing BEST small format interchangeable core master key system?
That is what the 7KC is built for. It takes the BEST 7-pin solid brass small format interchangeable core, so a core pulled from your existing SFIC system drops straight in and the lock joins the master key hierarchy with no rekeying at the bench. Cores are swapped with a control key in seconds, which is how you handle a lost key or a departed tenant on a fleet of doors. The BEST Patented Keying System is available as an option where you need key control on blanks.
5) What is the closest equivalent to the BEST 7KC storeroom lever from another manufacturer?
The Hager 2580 with Withnell lever is the nearest match: it is a Grade 2 storeroom cylindrical lock with a door thickness range of 1-3/8 inch to 2 inch, the same grade, function and thickness coverage the 7KC storeroom lever carries. The difference is the cylinder. The 7KC is built around the BEST 7-pin small format interchangeable core, so a facility already keyed on SFIC keeps its keying system and can rekey by pulling the core. The Hager 2580 is a fixed-cylinder storeroom lock, so specifying it means a separate keying path for that opening.
6) Is there a Grade 2 storeroom lever that takes a Schlage C keyway instead of a small format interchangeable core?
Yes. The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, covering doors 1-3/8 inch to 1-3/4 inch thick. Within the AG series the AG00 entrance lever and AG03 classroom lever are supplied with a 6-pin Schlage C keyway, so a building already master keyed on Schlage C can stay on that keyway. The BEST 7KC storeroom lever instead uses the BEST 7-pin solid brass interchangeable core with the optional BEST patented keying system, and it covers doors up to 2 inch thick where the AG05 stops at 1-3/4 inch.
7) The door needs to release on a fire alarm signal - can a BEST 7KC storeroom lock be used?
No. The 7KC storeroom lever is a mechanical lock with no electrified option. For an opening that has to unlock on alarm or from an access control panel, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever operating on 12VAC/DC, offered with the NZ lever and D rose and in a keyed 12VAC/DC version, for doors 1-3/4 inch to 2 inch. Fail safe means the lever unlocks when power is removed, which is the opposite of the always-locked outside lever a storeroom function gives you.
8) Do I need to specify handing when I order a BEST 7KC lever lock?
No handing to specify. The 7KC is non-handed, so one lock covers left and right hand doors and you can stock a single part number across a building. That also means a lever pulled off a returned or reworked opening goes straight onto the next door regardless of swing.
9) Is a Grade 2 BEST 7KC lever enough for a school or hospital corridor, or should I be buying Grade 1?
Grade 2 in the 7KC is medium duty, which suits storerooms, offices, tenant spaces and back-of-house doors that see moderate traffic. For a high-traffic corridor or a door that gets abused, step up to a Grade 1 cylindrical lock: the Falcon K Series and the Corbin Russwin CL3100 Series are both Grade 1 cylindrical lever locks we carry, and the CL3100 is vandal resistant. Note those are non-keyed passage functions, so match the function you need when you spec.
10) What is a good alternative to the BEST 7KC if I do not run a BEST interchangeable core system?
If you have no SFIC program, the interchangeable core is cost you will not use. The Hager 2580 with the Withnell lever is a Grade 2 storeroom cylindrical lock covering 1-3/8 inch to 2 inch doors, the same thickness range as the 7KC. The Cal-Royal AG05 is another Grade 2 storeroom lever, with a deadlocking latchbolt, for 1-3/8 inch to 1-3/4 inch doors. Both use conventional cylinders, so they key into a standard pin tumbler system rather than a core system.
11) Which lever styles does the BEST 7KC come in, and are they ADA compliant?
Three levers: the 14 curved with return, the 15 contour with angle return, and the 16 curved without return. All operate with a push rather than a grasp and twist, and the 7KC meets ANSI A117.1 section 404.2.6 and Illinois Accessibility Standard 400.310 for accessible design. If you are working in California and the opening is fire rated, the 14 and 15 levers are the ones that conform to Title 24.
12) Which lever lock should go on the doors that do not need to be keyed, to match a set of BEST 7KC storeroom locks?
Storeroom function on the 7KC means the lever is keyed and always locked from outside. For corridor, hall and closet doors on the same job that only need latching, the Grade 2 non-keyed options include the Falcon B101, a Grade 2 medium duty cylindrical passage lever with a non-handed design, and the Hager 2510 Grade 2 passage lever with the Withnell design for doors 1-3/8 inch to 2 inch. The Hager 2510 shares the same door thickness range and lever family as the Hager 2580 storeroom lock, which keeps trim consistent if the keyed openings are Hager. The Arrow GL01 is a Grade 2 non-keyed passage lock with the Sierra lever for doors 1-3/4 inch to 2 inch.
13) Will a Grade 3 residential lever work in place of a BEST 7KC storeroom lock on a commercial door?
They are not interchangeable for a commercial specification. The 7KC storeroom lever is a commercial Grade 2 lock, medium duty, UL listed for 3-hour A label single doors up to 4 feet by 8 feet. The Cal-Royal AUS00 entrance/office lever is Grade 3, the Callan Artino and Bennett entrance leversets are Grade 3, and the Kwikset 200BRNL Breton passage lever is Grade 3 for doors 1-3/8 inch to 1-3/4 inch. Those Grade 3 sets also carry entrance, passage or privacy functions rather than storeroom, so the outside lever does not stay locked with key retraction the way a storeroom function does.
14) What looks like a substitute for a BEST 7KC storeroom lever but will not lock the door?
Dummy and half dummy levers share the trim appearance but have no latch and no cylinder, so they cannot replace a keyed storeroom lock. The Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever, the Callan Bentley is a Grade 2 dummy lever, and the Baldwin Estate 5103 comes in left hand and right hand half dummy versions with the 5048 rose. Emtek supplies Arts and Crafts and Cortina levers as dummy pairs. These are for inactive leaves and closet faces. The 7KC storeroom lever is keyed with a single cylinder and secures the opening.
15) Is there a lever lock that does the same job as a storeroom lock without issuing keys?
Mechanical keypad leversets remove the key from the equation. The Lockey 1150 is a heavy duty mechanical keypad lever set with passage function for doors 1-1/8 inch to 2 inch, the 1150S version adds an adjustable backset, and the Lockey 2835DC is a double combination mechanical keyless lever lock covering doors 1 3/16 inch to 2 inch. The Delaney LP250 is a Grade 2 electronic keypad leverlock. The BEST 7KC storeroom lever is a non-electronic mechanical lock with a keyed single cylinder, so it stays on the existing key system rather than a code that has to be managed and changed.
16) For a classroom or a patient room, what function should be specified instead of a storeroom lever?
Storeroom function on the 7KC keeps the outside lever locked at all times and is meant for supply rooms and mechanical spaces. For a teaching space, the Dexter C1000 classroom lever is Grade 1 with a clutching keyed design for doors 1-3/8 inch to 1-3/4 inch, and the C1000 classroom security version adds inside keyed control of the outside lever. For patient rooms and utility spaces the Dexter C1000 asylum function is Grade 1 for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a heavy duty asylum lock with a ball knob on a Schlage C keyway. The knob version is worth flagging where an accessible lever is required.
17) The tenant wants to lock the office from the inside - is that the same as a storeroom lever?
It is a different function. A storeroom lever such as the 7KC is keyed single cylinder with the outside lever always locked, so entry is by key only and there is no inside button. An entrance or office function lets the occupant lock and unlock the outside lever from inside: the Falcon B511CP6D is a Grade 2 medium duty entry/office cylindrical lever, the Hager 2525 is a Grade 2 commercial entry lock for doors 1-3/8 inch to 2 inch, and the Arrow HK11 is a turn-pushbutton entrance lock with a ball knob and conventional cylinder for doors 1-3/8 inch to 1-3/4 inch. For a bed or bath door the Arrow MK02-TA is a fire rated privacy lock with a tudor knob.
18) Which cylindrical lever locks cover a 2 inch thick door?
The BEST 7KC storeroom lever is prepared for doors 1 3/8 inch to 2 inch, so it spans thin hollow metal through 2 inch doors without a thickness kit. Among the alternatives, the Hager 2580 storeroom, Hager 2510 passage and Hager 2525 entry locks all cover 1-3/8 inch to 2 inch, and the Dexter C1000 asylum covers the same span. The Corbin Russwin CL3110 and CL33903 start at 1-3/4 inch and run to 2 inch, so they will not suit a 1-3/8 inch door. The Falcon K101 passage lock runs 1-3/8 inch to 2-1/4 inch.
19) Can a BEST 7KC storeroom lever be swapped onto a door that currently has an exit device or an escutcheon trim?
No, those are different door preparations. The 7KC is a bored cylindrical lever taking a 2-1/8 inch diameter cross bore and a 1 inch latch bore. A door fitted with a pushpad exit device takes lever trim instead: the Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device, and the Imperial USA ED-EL500HD is a heavy duty escutcheon lever trim in entry function. Those mount to the device, not to a cylindrical lock bore, so converting an opening in either direction means new door prep.
20) What finishes does the BEST 7KC storeroom lever come in to match the rest of my building?
Six finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, and 626 satin chrome. For most commercial work you want 626 satin chrome, the standard specification finish that matches the bulk of existing hardware in offices, schools and healthcare. 613 is the choice where the building runs a dark bronze look.
21) Does the BEST 7KC lever hold up to someone hanging on the lever or prying at it?
Through-bolt mounting studs tie the two roses together through the door, which resists lever torque far better than screws into a chassis alone, the usual failure point on abused doors. On the keyed lever there is no exposed keeper hole, and the lever only comes off once the core is pulled, so it cannot be stripped from the outside. Internal steel parts are corrosion treated for normal atmospheric conditions.
22) Is the BEST 7KC an electronic or access control lock?
Strictly mechanical. The 7KC is a keyed cylindrical lock with no electrification, no card reader and no wiring at the opening. If you need credential access or audit on that door, look at an electrified cylindrical lock such as the Corbin Russwin CL33900 Series fail safe lever, which runs on 12V AC/DC, or a standalone keypad lever like the Delaney LP250 where you want codes without pulling wire.
23) Is a Schlage cylinder adapter kit a way to put a different cylinder in a BEST 7KC lever?
It is not. The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, so it addresses Yale locks rather than BEST cylindrical levers. The 7KC storeroom lever is built for the BEST 7-pin solid brass small format interchangeable core, with the lever removable only after the core is pulled and no exposed keeper hole on keyed levers. Changing keyways on a 7KC means specifying the core, not adapting the lock body.
24) Which lever design and finish options should be matched when standardizing a building on a mix of brands?
The BEST 7KC storeroom lever is offered with the 14 curved with return, 15 contour with angle return, and 16 curved without return levers in finishes 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome and 626 satin chrome, with ANSI S3 or standard STK strikes. Series 14 and 15 levers conform to California Title 24. Peer lines carry their own lever names rather than these numbers - Hager uses the Withnell design across the 2510, 2525 and 2580, Arrow uses the Sierra lever on the GL01, and Corbin Russwin uses the NZ lever with D rose on the CL33903 - so matching across brands is a visual and finish-code exercise, not a part number one.
