BEST 11B70T – Frequently Asked Questions

1) Will a BEST 11B padlock take the same interchangeable core as the rest of my BEST locks?
Yes. The 11B Series padlock uses BEST's standard removable interchangeable core, the same core that goes into most other BEST product lines, so it can be masterkeyed into an existing STANLEY/BEST system regardless of what type or size of lock the rest of the building runs. Practically that means a facility already on a BEST core system can add padlocks to gates, lockers, and equipment without a second key. It also means rekeying is a core pull, not a lock replacement.
2) What shackle lengths does the BEST 11B padlock come in, and which one do I need for a hasp?
Four shackle lengths are offered on the 11B: 3/4 inch, 1-1/2 inch, 2 inch, and 4 inch, all on a 1/4 inch diameter bronze shackle with a 7/8 inch shackle width. The clearance you need is the hasp staple plus whatever the shackle has to loop through, so a flat hasp on a door is usually the 3/4 or 1-1/2 inch, while chain links, thick hasps, or a gate latch with a bracket in the way need the 2 or 4 inch. The 7/8 inch width is the fixed dimension, so check that your hasp staple opening accepts it before choosing length.
3) What is the difference between key retained and non-key retained on a BEST 11B padlock?
That is the T versus L option on the 11B. Key retained (T) holds the key captive while the padlock is open, so nobody can walk off with the key and leave the lock hanging unlocked. Non-key retained (L) lets the key come out in either position. Key retained is what most institutions specify for equipment and gate locks, because it forces the padlock to be relocked before the key is returned to the ring. Non-key retained suits a maintenance tech carrying one key across many locks who does not want to be tethered to each one.
4) What is the alternative to a BEST 11B padlock if my building is on a Sargent or Medeco key system instead?
Interchangeable core padlocks are keyed to the core system already in the building, so match the brand of your existing cores. On a Sargent removable core system the direct counterpart is the Sargent 60-858-2 removable core padlock with a 2 inch stainless steel shackle. If the site is not on a removable core program at all, the fixed-cylinder options are the Sargent 758 (key retaining, US4 satin brass) and the Sargent 858 (non-key retaining, stainless steel shackle), and Medeco offers the 5260 brass body padlock with a 7/16 inch shackle diameter on M3 key technology. The 11B is the right pick only where BEST cores are already the standard.
5) Does a 1/4 inch shackle padlock fit the same hasps as a 5/16 inch one?
Not always, and the difference runs the other way from what people expect. The 11B carries a 1/4 inch diameter shackle, which passes through anything a heavier shackle passes through, so a hasp drilled for a thicker lock will accept it. Going the other direction fails: a hasp staple sized for 1/4 inch will not take the 5/16 inch shackle on a Schlage KS23D/KS23F brass padlock or a Medeco 54515G. When you are standardizing a property, the 1/4 inch is the shackle that fits the widest range of existing hardware.
6) What is the closest equivalent to a BEST 11B padlock from another manufacturer for a facility already running removable cores?
The Sargent 60-858-2 is the closest peer in the set: it is a removable core padlock with a 2 inch stainless steel shackle, so it carries the same core-swap rekeying approach as the BEST 11B, which uses a standard removable interchangeable core that integrates across the BEST product line. The practical difference is which core family the padlock is bedded for - a Sargent removable core padlock takes a Sargent core, so it belongs on a Sargent-keyed facility rather than a BEST-keyed one. If the site is already master keyed on BEST cores, the 11B is the one that drops into the existing system without adding a second key family.
7) I need key retained padlocks so the key cannot be pulled while the lock is open - what are my options besides BEST 11B?
The BEST 11B is built either way: the keying axis covers T for key retained and L for non-key retained, so one series covers both habits. Among other manufacturers, the Sargent 758 is a key retaining standard padlock in a US4 satin brass finish. If instead you want the key to come out with the shackle open, the Sargent 858 is the non-key retaining version with a stainless steel shackle, and the Medeco 54515G XT electronic padlock is non-key retaining as well. Key retained is the usual pick for lockout and tag applications where the lock must not be walked away from while it is open.
8) What should I use instead of a BEST 11B padlock on an outdoor gate or a wash-down area?
The BEST 11B answers weather with material: a stainless steel substrate and a 626 satin chromium plated lockbody, with a bronze shackle. Where you want a body designed specifically around exposure, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less pop-out cylinder. The Medeco 54515G XT is rated for indoor and outdoor use and carries a 5/16 inch shackle. The ABUS T84MB/30 Nautic uses a black sleeve over the body with a 13/64 inch shackle and a 1-17/64 inch body, aimed at marine exposure. Pick by how much abrasion and spray the opening sees, and by whether the site's core system has to follow the padlock.
9) Is an ABUS 72/30 safety padlock a substitute for a BEST 11B?
They are not interchangeable in role. The ABUS 72/30 is an anodized aluminum safety padlock with a 1-1/4 inch body and a 3/16 inch shackle - a lockout and tagout style lock, typically assigned to a technician and hung on an energy isolation point. The BEST 11B is a stainless steel padlock with a 1/4 inch bronze shackle and a removable interchangeable core, meant to sit in a master keyed building system and be rekeyed by core swap. The ABUS 74/40 insulated safety padlock, with a 6-pin cylinder, 1/4 inch shackle and 1-1/2 inch body, and the ABUS 76/40 plastic-covered aluminum core padlock at 1/4 inch shackle and 1-37/64 inch width, sit on that same safety side. Buy the ABUS units for the lockout program and the 11B for the keyed access program.
10) The hasp on my gate needs a thicker shackle than 1/4 inch - what padlock takes its place?
The BEST 11B shackle is 1/4 inch in diameter with a 7/8 inch width, and shackle length runs 3/4 inch, 1-1/2 inch, 2 inch and 4 inch. Where the staple or hasp eye calls for more section, the Medeco 5260 in the 52 Series uses a 7/16 inch shackle on a brass body in satin chrome with M3 key technology. The Schlage KS23D/KS23F brass padlock and the Medeco 54515G both use a 5/16 inch shackle. Measure the hasp eye first, because a heavier shackle only helps if it passes through the existing staple - otherwise the hasp is replaced along with the lock.
11) Can I get a BEST padlock with a chain attached so it does not get lost?
Yes, the 11B offers three chain configurations plus the plain lock. M1 gives a bronze chain, M5 a galvanized steel chain, and M is the case drilled for a clevis only, so you attach your own chain or shackle hardware later. Ordering with no chain option gets the standard padlock. Bronze pairs with the bronze shackle for outdoor and coastal work; galvanized steel is the tougher chain for gates and yard equipment.
12) What does the ZZ double lockout option on a BEST 11B padlock do, and when would I need it?
ZZ is the double lockout device option on the 11B, and F3 is the frangible option, with a standard no-option build as well. Double lockout is the configuration used where two separate keyholders each have to release the lock before it opens, which is how lockout/tagout and dual-custody applications are handled. Frangible is the break-away build used where the lock has to fail under force rather than hold, typically on emergency egress and safety devices. If you do not need either behavior, order standard.
13) Is the BEST 11B padlock suitable for outdoor gates and exterior use?
The 11B is built for corrosion exposure: bronze shackle, stainless steel substrate, and a 626 satin chromium plated lockbody. Bronze and stainless are the two materials that hold up in wet and coastal air where a plated steel shackle rusts and seizes. Pair it with the M1 bronze chain rather than the galvanized steel one if the lock lives outside full time.
14) Is a BEST 11B interchangeable core padlock the right lock for electrical lockout tagout?
Only in the double lockout form, and even then it is a keyed security padlock rather than a dedicated safety lock. The 11B ships in a ZZ double lockout option, but for standard LOTO work most electricians reach for a nonconductive safety padlock instead: the ABUS 74/40 insulated safety padlock with a 6-pin cylinder, 1/4 inch shackle diameter and 1-1/2 inch body, or the ABUS 76/40 plastic covered aluminum core padlock, also 1/4 inch shackle. The ABUS 72/30 anodized aluminum safety padlock, 1-1/4 inch body with a 3/16 inch shackle, is the lighter option for smaller devices. Choose the 11B when the lock has to sit on the building master key system.
15) How do I rekey a BEST padlock after an employee leaves?
Pull the core and drop in a new one. The 11B uses a removable interchangeable core, so rekeying takes a control key and seconds per lock instead of a locksmith re-pinning or replacing the padlock body. For a property manager turning over tenants or a facility with staff churn, that is the whole reason to run a BEST core program: one core change covers the padlock, and the same core stock serves the doors.
16) I want an audit trail on padlocked access points - what replaces a mechanical padlock like the BEST 11B?
The Medeco 54515G XT is the electronic option in this class: an indoor/outdoor electronic padlock, non-key retaining, with a 5/16 inch shackle, supplied with cylinder. It changes access control from a cut key and a pinned core to an electronic credential. The BEST 11B stays mechanical - access is managed by swapping the interchangeable core, and the same key system can carry across STANLEY/BEST locks of any type, size or style. Sites usually run electronic on the handful of high-value points that need a record and keep mechanical interchangeable core padlocks everywhere else.
17) Which padlock comes with a chain so it stays attached to the gate or panel?
That is a BEST 11B configuration rather than a separate model: the chain axis covers M1 bronze chain, M5 galvanized steel chain, and M for a case drilled for clevis only if you are supplying your own attachment, with a standard no-chain build as well. There are also device options - F3 frangible and ZZ double lockout. Among the other padlocks in the set, none is described with a chain or clevis case, so the 11B is the one to specify when the lock must not leave the opening.
18) Two men need to sign off before a padlock opens - can I get that in a BEST 11B or do I need something else?
The BEST 11B offers a ZZ double lockout device option, which is the configuration used where two separate keys or authorities must be satisfied. There is also an F3 frangible option for cases where the lock is meant to break away under load rather than resist it. Neither the Sargent 758 and 858 padlocks nor the ABUS safety padlocks in this set are described with a double lockout arrangement, so specify the 11B with the ZZ option rather than looking for an equivalent elsewhere.
19) How does the Sargent KESO 82-856 differ from the BEST 11B for a high security opening?
The Sargent 82-856 is a non-key retaining padlock on the KESO platform with a 2 inch by 2 inch brass case and a stainless steel shackle, so key control sits in the KESO cylinder. The Medeco 5260 takes a similar approach with M3 key technology in a 52 Series brass body. The BEST 11B puts its key control in the interchangeable core instead, which is what lets a facility rekey by pulling the core and expand the same master key system across other BEST hardware. The decision is usually which key system the building is already standardized on, since mixing platforms means carrying two key rings.
20) Does the BEST 11B padlock come with a core and key, or do I order those separately?
The 11B is specified by shackle length, keying retention, chain option, and device option. Core and keying are handled through your BEST core program, which is what lets the padlock join the building master key system in the first place. If you are not already running BEST cores, get the core and keying sorted with your locksmith at the same time you order the padlock body, otherwise you will have a lock you cannot operate.
21) Can I get BEST padlocks marked with department or building numbers?
Special case embossing is offered on the 11B, which is how facilities tag padlocks by building, department, or gate number so a lock that turns up on the wrong hasp can be returned. Combined with the chain options, that is the usual setup for a large campus running dozens of identical padlocks on a single master key system.
