BEST 7KC30Y15DSTK626 – Frequently Asked Questions

1) What does the exit function on the BEST 7KC lever lock actually do?
Exit (Y) function means the lock operates from one side only, with no key and no locking. The 7KC in this configuration is listed as non-keyed, so there is no cylinder to manage and no way for an occupant to secure the opening. It is the lock you put on a door people only need to come out of, like a stair discharge or a one-way corridor door. If you need the door lockable or keyed, you want a storeroom, entrance, or classroom function instead.
2) Will the BEST 7KC lever lock fit my existing door prep?
It goes into standard cylindrical prep: 2-1/8 inch diameter cross bore for the chassis and a 1 inch bore for the latch tube, on doors 1-3/8 to 2 inches thick. Backset is ordered as either 2-3/8 or 2-3/4 inches, which are the two common commercial bores, so an existing 161 prep normally takes it without rework.
3) Do I need to specify handing for the BEST 7KC lever lock?
No. The 7KC is non-handed and the lockset reverses for either hand of door without removing the lever, so one part number covers left and right openings. For a property manager buying spares across a building, that means a single stock item instead of two.
4) Can I use the BEST 7KC lever on a fire rated door?
It is UL listed for 3-hour A label single doors up to 4 by 8 feet. That covers most rated stair and corridor leaves. Pairs and oversized leaves fall outside that listing.
5) Is a Grade 2 lever lock like the BEST 7KC strong enough for a school or office corridor?
The 7KC is rated Grade 2 medium duty to BHMA A156.2 Series 4000, which is the right level for moderate traffic: offices, retail, multi-tenant residential, back-of-house. It uses through-bolt mounting studs for torque resistance and corrosion-treated internal steel. For a high-abuse opening, a gymnasium door or a main entrance taking constant traffic, step up to a Grade 1 cylindrical lock such as the Falcon T101 or the Corbin Russwin CL3100 Series.
6) What is the closest Grade 2 medium duty cylindrical lever equivalent to the BEST 7KC exit function lock?
For a same-grade, same-duty alternative, the Falcon B101 is a Grade 2 medium duty cylindrical lever lock, and the Falcon B Series B511CP6D is also Grade 2 medium duty. The difference is function: the BEST 7KC covered here is the exit (Y) function, non-keyed, while the B101 is passage/hall/closet and the B511CP6D is entry/office. Exit function differs from passage in that the outside lever is fixed and there is no outside operation, so if the opening genuinely needs free egress with a rigid outside lever, match the function first and the grade second.
7) I need a heavier duty lever than the BEST 7KC for a high traffic corridor - what should I look at?
The 7KC is rated Grade 2 medium duty. If the traffic warrants a step up, the Falcon K101 is a Grade 1 heavy duty cylindrical passage lock that is fire rated and covers doors 1-3/8 inch to 2-1/4 inch, and the Falcon T101 is a Grade 1 heavy duty cylindrical passage lever. Corbin Russwin CL3110 is another Grade 1 fire rated passage cylindrical lever for 1-3/4 inch to 2 inch doors. All three are passage function rather than exit, so confirm whether the opening needs the fixed outside lever the exit function provides.
8) The opening needs to be keyed from the outside - what takes the place of the BEST 7KC exit lever there?
The 7KC exit (Y) function is non-keyed, so it will not give you outside key control. For a keyed Grade 2 cylindrical lever in the same family of applications, the Hager 2580 is a Grade 2 storeroom lever for 1-3/8 inch to 2 inch doors, the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, and the Hager 2525 is a Grade 2 entrance lever. Storeroom keeps the outside lever locked at all times with key entry; entrance allows the outside lever to be unlocked for periods of open access.
9) Is a Grade 2 passage lever the same thing as the BEST 7KC exit function lock?
No, and this is the most common mis-substitution. The BEST 7KC covered here is exit (Y) function with a fixed outside lever, while a passage lever such as the Hager 2510 Grade 2, the Accentra 5301LN Augusta Grade 2, the Accentra 4601LN Grade 2, or the Arrow GL01 Grade 2 Sierra lever gives free operation from both sides. All of those are non-keyed Grade 2 cylindrical levers like the 7KC exit, so they look interchangeable on a spec line, but the outside lever behavior is not the same.
10) Does this BEST lever lock meet ADA requirements for accessible openings?
The 7KC lever meets ANSI A117.1 section 404.2.6 and Illinois Accessibility Standard 400.310, and it is a lever rather than a knob, so it operates without grasping or twisting. All three lever styles offered, 14 curved with return, 15 contour with angle return, and 16 curved without return, are part of the same series.
11) Which strike should I order with the BEST 7KC lockset?
Two choices: S3, the full ANSI strike with the 4-7/8 inch face used in most hollow metal frames, or STK, the standard strike for a smaller frame lip prep. Match whichever is already cut into the frame, since swapping between the two means reworking the jamb.
12) What is the difference between an exit function lock and a passage lever?
Both are non-keyed and both always retract the latch, but they differ by side. A passage set turns from either side, which is what you want on a hall or closet door. The BEST 7KC exit function operates from the inside only, so there is no operating trim to grab from the outside. If what you actually need is free operation both ways, look at a Grade 2 passage lever like the Falcon B101 or the Hager 2510, or a Grade 1 passage lever like the Corbin Russwin CL3110.
13) Does the BEST 7KC exit lockset take a BEST interchangeable core?
The 7KC Series is built around the BEST interchangeable core system, which is what lets a facility rekey in seconds without pulling locks off doors. The exit function version is non-keyed, though, so there is no core in this one. Where you need a keyed opening on the same key system, order a keyed 7K function and the whole set stays on one BEST keyway.
14) Can I use a residential Grade 3 lever on the same doors as the BEST 7KC?
The 7KC is a commercial Grade 2 lever. Grade 3 levers such as the Kwikset 200BRNL Breton passage for 1-3/8 to 1-3/4 inch doors, the Callan Asheville passage, or the Cal-Royal AUS00 entrance/office for 1-3/8 to 1-3/4 inch doors are built to a lighter cycle and strength standard, and none of them offer exit function. If your specification calls out ANSI/BHMA Grade 2 for commercial openings, a Grade 3 lever will not satisfy it.
15) What should I order for the inactive leaf or a pull-only door instead of the BEST 7KC exit lever?
The 7KC exit function includes a working latch and chassis, which an inactive leaf or a closet pull does not need. For trim only, the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever and the Callan Bentley is a Grade 2 dummy lever; Baldwin Estate 5103 half dummy levers are offered in left hand and right hand versions. Dummy trim is surface mounted with no latch, so it will not fill a bored 2-1/8 inch chassis prep the way the 7KC does.
16) We want keypad access instead of a key on this opening - what replaces the BEST 7KC?
The 7KC is a mechanical, non-electronic lever. If the opening needs code entry, the Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Lockey 1150 and 1150S are mechanical keypad heavy duty lever sets for doors 1-1/8 inch to 2 inch, with the 1150S offering an adjustable backset. The Lockey 2835DC is a double combination keyless lever lock with passage function for 1-3/16 inch to 2 inch doors. These change how the door is operated from the outside, so the exit function behavior of the 7KC is not carried over.
17) Does the BEST 7KC work for a patient room or utility door, or do I need a different function?
Exit function on the 7KC is not the same as an asylum or institutional function. For those openings, the Dexter C1000 asylum (F87) is Grade 1 for doors 1-3/8 inch to 2 inch, and the Arrow MK33 is a Grade 2 heavy duty asylum/institution/utility lock with a ball knob and Schlage C keyway. Asylum function keys both sides; the 7KC exit function leaves the inside free for egress at all times.
18) Which alternatives to the BEST 7KC carry a fire rating for a labeled opening?
The 7KC exit lever is UL listed for 3-hour A label single doors up to 4 feet by 8 feet. Among comparable cylindrical levers, the Corbin Russwin CL3110 passage is listed with a fire rating for 1-3/4 inch to 2 inch doors, the Falcon K101 Grade 1 passage is fire rated for 1-3/8 inch to 2-1/4 inch doors, and the Arrow MK02-TA privacy knob lock carries a fire rating. Always confirm the specific label and door size the opening requires.
19) Our access control plan needs an electrified lever - is there a version of the BEST 7KC for that?
The 7KC exit lever is a mechanical lockset with no electrical option. For an electrified cylindrical lever, the Corbin Russwin CL33903 is a Grade 1 fail safe lever running 12VAC/DC on doors 1-3/4 inch to 2 inch, offered with an NZ lever and D rose. Fail safe means the lever unlocks on loss of power, which is a different egress strategy than the always-free inside lever of the 7KC exit function.
20) Is the BEST 7KC the right choice for a restroom door, or should I use a privacy lock?
A restroom typically calls for privacy function, which the 7KC exit lever does not provide - it has no inside push button or thumbturn to secure the door. For privacy, the Hager 2540 Grade 2 covers 1-3/8 inch to 2 inch doors, the Arrow MK02-TA is a Grade 1 privacy lock with a Tudor knob for 1-3/4 inch to 2 inch doors, and the Kwikset 300BRNL Breton is a Grade 3 privacy lever for 1-3/8 inch to 1-3/4 inch doors.
21) What finishes does the BEST 7KC lever lock come in for matching existing hardware?
Six BHMA finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 625 bright chrome, and 626 satin chrome. For most commercial buildings the match is 626 satin chrome, which is the standard institutional finish.
22) The BEST 7KC backsets top out at 2-3/4 inch in stock - what else fits a standard commercial prep?
The 7KC exit lever is stocked in 2-3/8 inch and 2-3/4 inch backsets, which covers standard commercial door prep. Peers on the same standard preps include the Cal-Royal AG00 entrance lever in 2-3/8 inch backset and the Cal-Royal AG03 classroom lever in 2-3/4 inch backset, both Grade 2 with 6-pin Schlage C keyways. Note those two are keyed functions while the 7KC exit function is non-keyed.
