BEST 3L7RD2626 – Frequently Asked Questions

1) What size hole and hole spacing does the BEST 3L cabinet lock need in the cabinet door?
Prep for the 3L is a 1-1/8 inch diameter opening for the cylinder housing, with mounting holes on a 1-39/64 inch by 1-1/4 inch pattern. The case itself measures 1-21/32 by 2-1/8 by 21/32 inches, so you need that much clear space behind the door face. Backset is 7/8 inch from the door edge to the cylinder center. Mark from the manufacturer template rather than eyeballing the pattern.
2) Will the 3L cabinet lock work on a left-hand and a right-hand cabinet door?
Non-handed, so one part number covers both swings. That matters if you are locking a run of cabinets that open in different directions, or standardizing a stock room shelf on a single item instead of stocking a left and a right. If you need a handed cabinet lock that can be flipped in the field instead, the Sargent 1655 is field reversible.
3) Does the BEST 3L cabinet lock come with a core, or do I have to order the core separately?
The 3L ships as a 7-pin housing less core. The housing takes a BEST 7-pin interchangeable core, which you buy and key separately, so a locksmith or facility can key the cabinet into an existing BEST 7-pin master system rather than getting a one-off key. Budget for the core, and specify the keyway and keying when you order it. If you want a cabinet lock that arrives complete with a fixed cylinder, the Sargent 4142 is a 6-pin brass cylinder unit.
4) Will a 3/4 inch bolt throw engage the keeper on my existing cabinet frame?
The deadbolt throws 3/4 inch and the bolt measures 1-1/8 by 3/16 inches, so the strike or keeper on the frame has to sit within that reach of the bolt when the door is closed. Measure the gap between the closed door face and the frame surface the keeper mounts to. Anything more than about half that throw and the bolt will not be fully captured. A keeper is installed on the cabinet frame as part of the job.
5) Does the 3L cabinet lock lock automatically when the door shuts, or do I have to key it?
Manual. The deadbolt is thrown and retracted by key only, so somebody has to lock the cabinet after closing it. That is the right behaviour for a coin box or a medication cabinet where you want a positive, deliberate lock, but it is the wrong choice if you need it to secure itself every time. The key can be pulled in either the locked or unlocked position, so it will not get held hostage in the cylinder when the cabinet is open for the day.
6) What is the closest keyed cabinet lock to the BEST 3L Series if a 6-pin cylinder is acceptable?
The Sargent 1655 is a 6-pin cabinet lock with field reversible handing, which makes it the nearest keyed mechanical alternative to the BEST 3L Series. The 3L uses a 7-pin housing and is non-handed as supplied, with a 7/8 inch backset and a 3/4 inch throw. Choose the 1655 where the cabinet program is standardized on a 6-pin keyway and handing needs to be set in the field; choose the 3L where the facility keys to a 7-pin system.
7) The cabinet door needs a horizontal lock rather than a vertical one. What takes the place of the BEST 3L?
The Sargent 4142 is a horizontal cabinet lock with a 6-pin brass cylinder, so it suits an opening where the case has to sit horizontally. The BEST 3L Series is built for vertical rim mounting with a 1-39/64 inch by 1-1/4 inch hole spacing pattern, and its case orientation is not something that changes in the field. Confirm the orientation off the cabinet before ordering either one.
8) Is there a cabinet lock that does the same job as the BEST 3L without issuing keys?
The Lockey C170 is a mechanical surface mount keyless digital combination cam cabinet lock with a low profile design, and it fits doors 1-1/8 inch to 2 inch thick. It replaces key control with a combination, so no cores or keys have to be cut or tracked. The BEST 3L Series is a keyed lock with a 7-pin housing whose key can be withdrawn in both the locked and unlocked positions. Use the C170 for cabinets shared by rotating staff, and the 3L where the cabinet has to key into the building system.
9) What replaces a mechanical cabinet lock like the BEST 3L when the cabinet has to be tied into access control?
The SDC 290 Series is a micro cabinet electric bolt lock with dual voltage operation, and the DynaLock 1410 Series is a dual voltage cabinet lock rated heavy duty. Both are electric locks that release from a control system rather than from a key at the cabinet. The BEST 3L Series is a mechanical dead-locking lock that must be locked by key after the door is closed, and it needs no power or wiring at the cabinet. Pull power to the cabinet before specifying either electric option.
10) Which cabinet lock should be used instead of the BEST 3L when an audit trail or multiple users are required?
The SDC 295 Series is a battery powered programmable cabinet lock with a 30-user keypad, and the HES KP20 is a stand-alone keypad cabinet lock carrying a Grade 1 rating. Both let more than one credential open the same cabinet without cutting more keys. The BEST 3L Series is a keyed dead-locking lock, so every additional user means another key on the same 7-pin system. For medication or narcotics storage where individual user codes are required, the keypad locks are the ones to look at.
11) Should I use a rim-mounted cabinet lock like the BEST 3L or a keyless keypad cabinet lock?
A keyed rim lock like the 3L is what you want when the cabinet needs to sit in a master key system and be opened by whoever already carries the building key, with no batteries, no wiring and no user list to maintain. Go keyless instead when the people opening the cabinet change often or you do not want to issue keys at all: the HES KP20 is a stand-alone keypad cabinet lock, the SDC 295 is battery powered with a 30-user keypad, and the Lockey C170 is a mechanical combination cam lock with no power at all. For a cabinet tied into an access control system, the SDC 290 and DynaLock 1410 are electric bolt locks and the HES KS200 runs Wiegand wired access control.
12) Is a 7-pin cabinet lock worth it over a 6-pin for a commercial building?
The 3L uses a 7-pin tumbler cylinder, 1-1/8 inch diameter and 1-13/64 inch long. The practical reason to go 7-pin is not just pick resistance, it is key control: a 7-pin BEST system gives you deeper masterkeying levels, so cabinet locks can sit under the same hierarchy as the doors without collapsing your master. Most cabinet locks on the market are 6-pin, the Sargent 1655 and 4142 among them, and a 6-pin cabinet lock cannot be keyed into a 7-pin system.
13) What is a vertical rim cabinet lock and does it fit a drawer?
Rim mount means the lock case bolts to the back face of the cabinet door and the bolt throws against a keeper on the frame, rather than being let into a mortise. Vertical means the case sits upright and the bolt throws vertically, which suits a hinged cabinet door with the keeper on the frame above or below the lock. It is not a drawer lock. For drawers you want a cam or drawer-specific lock such as the Sargent 4152 or 4252, both built for drawers.
14) What else do I need to order to install a BEST 3L cabinet lock?
Three things beyond the lock itself. A BEST 7-pin interchangeable core, because the housing ships less core. A keeper for the cabinet frame for the 3/4 inch bolt to throw into. And fasteners suited to your cabinet door material and thickness, since sheet metal, plywood and particle board each want a different screw. The finish you pick, one of nine BHMA numbers, only affects the visible cylinder face.
15) Are the Sargent KESO 4152 and 4252 cabinet locks a substitute for the BEST 3L Series?
Not directly. The Sargent KESO F1 4152 Series and KESO F1 4252 Series are cabinet locks for drawers, with the 4252 offering field reversible operation, and both are built around the KESO F1 security system. The BEST 3L Series is a vertical rim mounted cabinet lock with a 7-pin housing and a 7/8 inch backset. The KESO parts suit a drawer bank keyed into a KESO system; they do not drop into a 3L rim preparation.
16) What cabinet lock is used on a server rack or IT enclosure instead of the BEST 3L?
The HES KS-M is a mechanical server cabinet lock and the HES KS200 is a server cabinet lock with Wiegand integrated wired access control, both Grade 1. They are built for rack and enclosure doors, with the KS200 reporting to a wired access control head end. The BEST 3L Series is a commercial cabinet lock for storage casework, dead-locking by key with a 3/4 inch throw. For a data closet where the rack has to report on the same system as the room door, the KS200 is the one to spec.
17) For a facility standardizing cabinet locks across many casework doors, which options carry a Grade 1 rating?
Among cabinet locks, the HES KP20, HES KS-M, and HES KS200 are each listed at Grade 1. The BEST 3L Series is a commercial cabinet lock with a stainless steel bolt, phosphor bronze springs, and brass components, and it keys into a 7-pin system, which is what usually decides a facility standard where the cabinets share the building keyway. Where a written spec calls out Grade 1 on cabinet hardware, the HES parts answer that line directly.
18) What finishes does the BEST 3L cabinet lock come in, and which one matches the rest of my hardware?
Nine finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, 626 satin chrome, and 690 statuary dark bronze. Those are BHMA finish numbers, the same codes stamped on the rest of your door hardware, so if the building is standardized on 626 you order the lock in 626 and it matches. Only the exposed cylinder face shows on the cabinet door, so the finish choice is cosmetic, not structural.
19) Is the BEST 3L cabinet lock built for daily use in a hospital or school, or is it light-duty?
Built for commercial service: stainless steel bolt, phosphor bronze springs and brass components. Phosphor bronze springs are the reason it keeps working after years of cycles, they resist taking a set the way plain steel does, and a stainless bolt will not seize in a damp mechanical room or a kitchen area. It is spec'd for commercial applications, not residential furniture.
20) I need to lock a server rack or a data cabinet, is this the right lock?
The 3L is a keyed cabinet lock for storage cabinets, coin boxes, med carts and tool cabinets, and it is fine on a rack door mechanically if the prep works. But if the reason for locking the rack is audit trail or credentialed access, a keyed lock gives you neither. The HES KS-M is a mechanical server cabinet lock and the HES KS200 is a server cabinet lock with Wiegand wired access control that ties into the building system, both Grade 1.
21) Does the BEST 3L Series come in enough finishes to match existing cabinet hardware, or is another lock needed?
The BEST 3L Series is offered in nine finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, 626 satin chrome, and 690 statuary dark bronze. That range covers most casework programs without moving to a different lock. The keypad and electric alternatives such as the HES KP20 and the SDC 295 are selected on function rather than on matching a brass or bronze cabinet pull.
