BEST 7KCS2613 – Frequently Asked Questions

1) Will the BEST 7KCS strike package work on a 1-3/8 inch door or do I need a different strike?
Both door thicknesses are covered, but by different strikes. The STK strike (2 3/4 x 1 1/8 inches, curved lip and box) is the ANSI A115.2 strike for 1 3/8 inch doors, and the S3 strike (4 7/8 x 1 1/4 inches, curved lip and box) is the ANSI A115.2 strike for 1 3/4 inch doors. The 6K/7K cylindrical lever locks these strikes serve run 1 3/8 to 2 inch door thickness, so pick the strike that matches the frame prep you actually have, not just the door leaf.
2) What is the difference between the ANSI strike package and the T-Series strike package on the BEST 7KCS?
Those are the two orderable strike packages. The ANSI package is the 4 7/8 x 1 1/4 inch S3 style strike with curved lip and box, the full ANSI A115.2 frame prep. The T-Series package is the smaller T-strike footprint. If your frame is already cut for a 4 7/8 inch ANSI prep, order the ANSI package or you will be looking at exposed metal around a short strike. If the frame has the small rectangular prep, the T-Series package is the one that drops in.
3) Which BEST locks does the 7KCS strike package fit?
The 7KCS strike package is built for BEST 6K and 7K Series cylindrical lever locks. That covers the backset range those locks are made in: 2 3/8 inch on the 72KC, 2 3/4 inch on the 73KC, 3 3/4 inch on the 74KC, and 5 inch on the 75KC. The strike itself is a frame-side part, so the backset of the lock does not change which strike you need; what decides it is the frame prep and the door thickness.
4) Will this strike catch a BEST 6K/7K latch properly, or do I need a deeper strike box?
The latch on the 6K/7K cylindrical lever locks is a 1/2 inch throw deadlocking latch, and both strikes in the package come with a box behind them, so the bolt has somewhere to go and the deadlocking plunger has a lip to ride. A 1/2 inch throw is short, which means strike alignment matters more than usual: if the strike sits proud or the box is shimmed shallow, the latch will not fully deadlock and the door can be loided.
5) Can an Adams Rite 4510 deadlatch be used in place of a BEST 7KCS strike package?
No - these solve different problems. The BEST 7KCS is a strike package: STK strikes at 2 3/4 inch x 1 1/8 inch and S3 strikes at 4 7/8 inch x 1 1/4 inch, both with curved lip and box, that mount in the door frame opposite a BEST 6K/7K cylindrical lever lock. The Adams Rite 4510 is a Standard Duty electrified deadlatch, a Grade 1 latching device that mounts in the door itself. Ordering the 4510 when the lever lock is already installed and only the frame strike needs replacing leaves the opening without the strike it needs.
6) What finishes does the BEST 7KCS strike package come in, and can I match the levers already on my doors?
Six finishes are offered, and all six are available on both the ANSI and the T-Series package: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oxidized satin bronze oil rubbed, 625 bright chromium plated, and 626 satin chromium plated. Those are the same finish codes BEST plates the 6K/7K levers and roses in, so if you know the number on the existing lock you can order the strike to match without eyeballing it. 626 satin chrome is the one most commercial openings are already running.
7) I am replacing a damaged strike on a BEST lever lock. Do I need to buy the whole lockset?
No. The 7KCS is sold as a replacement strike package on its own, so a bent lip, a chewed-out box, or a strike that has been filed to death on a sagging door can be swapped without touching the lock, the core, or the latch. Order the package that matches your frame prep, ANSI or T-Series, in the finish already on the opening.
8) Can I standardize BEST 7KCS strikes across a whole building with mixed door thicknesses?
Partly. Doors at 1 3/4 inches take the S3 strike and doors at 1 3/8 inches take the STK, both to ANSI A115.2, so a facility running one door thickness can standardize on a single strike package and one finish. A building with both thicknesses needs both packages stocked. Since the 6K/7K locks cover 1 3/8 to 2 inch doors across four backsets, the practical way to standardize is by frame prep and finish rather than by lock model.
9) Is a cylindrical lock strike like the BEST 7KCS the right part for an aluminum storefront door?
Generally not. The 7KCS strikes serve BEST 6K/7K cylindrical lever locks, which bore through the door at 2 1/8 inches for the housing and 1 inch for the latch tube. A narrow stile aluminum storefront has nowhere near that much stile to give up. Storefront openings take a narrow stile deadlatch instead, such as the Adams Rite 4781 two point deadlatch with paddle, made for narrow stile doors, or the 4530 standard duty deadlatch with bolt holdback. Those are Grade 1 and are listed for 1-3/4 inch doors.
10) I need the door to release on a card reader. Will a BEST 7KCS strike do that?
No. The 7KCS is a mechanical strike with a curved lip and box; there is nothing electrified in it. For access control at the door you want an electrified latch instead of a plain strike, for example the Adams Rite 4300 Steel Hawk electrified deadlatch, a Grade 1 heavy duty unit with multi-voltage operation for 1-3/4 inch doors, or the standard duty 4510 electrified deadlatch with flat faceplate, also Grade 1 for 1-3/4 inch doors. Both are narrow stile style deadlatches, so they suit a different door than a bored cylindrical lever lock.
11) We standardize on Grade 1 hardware - how does the BEST 7KCS strike package compare to the Adams Rite 4300 on grade?
The BEST 7KCS strike package is built to support Grade 2 cylindrical lever lock systems and meets ANSI A115.2 frame prep, with STK strikes for 1 3/8 inch doors and S3 strikes for 1 3/4 inch doors. The Adams Rite Steel Hawk 4300 is a Grade 1 Heavy Duty electrified deadlatch for 1-3/4 inch doors. They are not interchangeable parts - the 7KCS is the frame-side strike for a bored lever lock, the 4300 is the door-side latching device - so a Grade 1 standard on the lockset does not turn the 4300 into a strike replacement.
12) Which latching hardware covers doors thinner or thicker than 1-3/4 inch?
The BEST 7KCS strike package covers door thicknesses from 1 3/8 inch to 2 inch, using STK strikes on 1 3/8 inch doors and S3 strikes on 1 3/4 inch doors per ANSI A115.2. The Adams Rite deadlatches in the comparable range - the 4300 Steel Hawk, the 4510, the 4530 and the 4781 - are each specified for 1-3/4 inch doors. On a 1 3/8 inch or 2 inch leaf, the BEST 6K/7K bored lock and 7KCS strike combination is the one that spans the range.
13) How much clearance does a BEST 6K/7K lever need at the frame or an adjacent wall?
The lever handle is 5 1/4 inches long with a return, and it projects 2 1/2 inches off the face of the door. That projection is what to check against a jamb, a return wall, or a door swinging into a tight vestibule before you commit to lever trim on that opening. The rose is the D style, 3 1/2 inches in diameter with concealed mounting screws.
14) Is a BEST 6K/7K strike and lock package heavy enough for a school corridor or a hospital?
The 6K/7K cylindrical lever locks the 7KCS strikes serve are a Grade 2 cylindrical lock system, specified for commercial use in offices, schools, healthcare, retail, warehouse, multi-tenant residential, and government buildings. Component parts are brass, bronze or zinc, with zinc dichromated steel internals. For a truly abusive corridor, Grade 1 is the heavier tier, but Grade 2 is the normal specification for interior commercial openings in these building types.
