BEST 41B70T – Frequently Asked Questions

1) Will a BEST 41B padlock work with my existing BEST interchangeable core key system?
The 41B Series takes the standard BEST removable interchangeable core, so it keys into the same system as the rest of your BEST hardware. That means one core pull to rekey a padlock rather than replacing the lock, and STANLEY/BEST locks of any type or style can be masterkeyed together with it. If your building already runs BEST IC cores on the doors, the padlocks fold into the same key control.
2) What shackle sizes does the BEST 41B bronze shackle padlock come in?
Shackle diameter is 3/8 inch across the 41B bronze shackle line, with a 7/8 inch shackle width (the clear opening between the legs). Clearance height is what you pick: 3/4 inch, 1-1/2 inch, 2 inch, or 4 inch. Measure the hasp staple or chain link you are locking through, then add enough height to close the shackle over it. The 3/4 inch is a tight anti-shim choice on a flush hasp; the 4 inch is for locking through gate chain or a thick staple.
3) What is the difference between key retained and non-key retained on a BEST 41B padlock?
That is the T versus L option. Key retained (T) will not release the key while the padlock is open, so the key stays captive at the lock and cannot walk off in someone's pocket with the padlock hanging open. Non-key retained (L) lets you pull the key out whether the lock is open or shut, which is what most maintenance techs want when they carry one key across a lot of locks. Lockout and equipment applications usually spec key retained; fleets of gate and storage locks usually spec non-key retained.
4) Is there a BEST 41B padlock option that resists bolt cutters?
Two options address attack. XSPL supplies a cut resistant shackle in place of the standard bronze one, and SH is the shrouded version, where the lock body wraps up around the shackle so there is very little shackle exposed to get a jaw onto, combined with the cut resistant shackle. For a gate or a yard container that has been hit before, SH is the one to spec. Note the shroud needs a hasp the body can sit over, so check the staple clearance before you order it.
5) What are the alternatives to a BEST 41B padlock if I am not on a BEST key system?
The 41B only earns its keep if you want BEST interchangeable cores. On another system, Sargent's removable core padlocks are the direct parallel: the 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle. If you do not need removable cores at all, the Sargent 758 is a key retaining padlock and the 858 is the non-key retaining version, both in US4 satin brass. Schlage's KS23D/KS23F is a brass body padlock with a 5/16 inch shackle. Those are conventional cylinder locks, so rekeying means pinning the cylinder rather than swapping a core in seconds.
6) Is the BEST 41B padlock the right lock for electrical lockout tagout?
No. Lockout wants a light, non-conductive, single-key personal lock, not a keyed-alike facility padlock on a shared master system. The ABUS 74/40 is an insulated safety padlock with a 6 pin cylinder, 1/4 inch shackle diameter and 1-1/2 inch body, and the ABUS 72/30 is an anodized aluminum safety padlock, 1-1/4 inch body with a 3/16 inch shackle. Those are the safety-lock family. Keep the 41B for gates, cages, storage and equipment security where you want it on the building master.
7) Can I standardize every padlock across my facility on one key?
That is the case for the 41B. Because it uses the same removable interchangeable core as the rest of the BEST line, padlocks, cylindrical locks and mortise locks all sit in one masterkey system that expands as the facility grows. A single grand master opens the padlocks on the roof hatches, the cages and the gates as well as the doors, and when a key goes missing you pull and swap cores instead of replacing hardware. Order the whole padlock fleet on the same keyway your doors already use.
8) What is the closest equivalent to a BEST 41B padlock if the site standardizes on Sargent keying?
The Sargent 60-858-2 is the nearest counterpart. It is a removable core padlock with a 2 inch stainless steel shackle, so it keeps the same removable-core approach the BEST 41B Series uses with its standard removable interchangeable core, and 2 inches is one of the shackle lengths the 41B is built in alongside 3/4 inch, 1-1/2 inch and 4 inch. The 41B carries a stainless steel substrate with a 626 satin chromium plated lockbody and a 3/8 inch bronze shackle.
9) Which padlock should be used instead of a BEST 41B when the key must stay in the lock or must not?
The BEST 41B Series is ordered either key retained or non-key retained, so both behaviors come from the same series. If the choice needs to be made across brands instead, the Sargent 758 is a key retaining standard padlock in a US4 satin brass finish and the Sargent 858 is a non-key retaining padlock with a stainless steel shackle, also US4 satin brass. The Medeco 54515G is non-key retaining as well.
10) Is an ABUS 72/30 safety padlock a substitute for a BEST 41B?
They do different jobs. The ABUS 72/30 is an anodized aluminum safety padlock with a 1-1/4 inch body width and a 3/16 inch shackle diameter, built light for lockout tagout use on a worker's own energy isolation point. The BEST 41B Series is a stainless steel substrate padlock with a 3/8 inch bronze shackle and a removable interchangeable core, intended to sit inside a masterkeyed system where STANLEY/BEST locks of any type or size share one key hierarchy. Related ABUS safety locks include the 74/40 insulated padlock with a 6-pin cylinder, 1/4 inch shackle diameter and 1-1/2 inch body width.
11) What outdoor padlock competes with a BEST 41B on an exposed gate or yard?
The Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less pop-out cylinder. The Medeco 54515G is an XT electronic indoor/outdoor padlock with a 5/16 inch shackle diameter, supplied with cylinder. The BEST 41B Series handles exposure through a WC weather cover option, a 626 satin chromium plated lockbody and a stainless steel substrate, and it can be ordered with an M1 bronze chain or M5 galvanized steel chain so the lock stays tethered to the gate.
12) Can I get a BEST padlock with a chain so it stays attached to the gate?
Yes, three case options cover it: M1 adds a bronze chain, M5 adds a galvanized steel chain, and M is the case drilled for a clevis with no chain supplied, so you can attach your own. Leave the option off and you get the standard case with no chain provision. Bronze chain suits coastal or wash-down locations where the steel would rust; galvanized is the cheaper general-purpose choice.
13) Will a BEST 41B padlock hold up outdoors on a gate or a rooftop?
Construction is aimed at it: stainless steel substrate with a 626 satin chromium plated lockbody, and a bronze shackle, which does not rust the way plated steel does. For exposed locations add the WC weather cover option, a flap over the keyway that keeps rain, grit and ice out of the core. Pairing WC with the M1 bronze chain gives you an all-corrosion-resistant assembly for coastal or wash-down duty.
14) Does a BEST 41B padlock come with the core and key, or do I order those separately?
The 41B is built around the standard BEST removable interchangeable core, and the core is the part that carries your keyway and your keying. Facilities running an existing BEST system almost always order the padlock and drop in a core from their own stock or have it keyed to their master. Decide the core and keying alongside the padlock so the lock arrives ready to hang, rather than as a body with an empty core hole.
15) Is a 3/8 inch shackle heavier duty than the padlocks I have now?
3/8 inch is a substantial shackle for a keyed facility padlock. For scale against other padlocks in the same class: the Medeco 5260 brass body lock runs a 7/16 inch shackle, the Schlage KS23D/KS23F a 5/16 inch, the Medeco 54515G a 5/16 inch, and the ABUS aluminum safety locks 3/16 to 1/4 inch. So the 41B sits at the heavy end of that group without going to the 7/16 inch class. If the existing locks on your gates are 1/4 inch or 5/16 inch aluminum-bodied, the 3/8 inch bronze shackle will need a hasp staple with a wider opening.
16) What do I have to specify when ordering a BEST 41B padlock?
Four decisions build the part: shackle length (3/4, 1-1/2, 2 or 4 inches), key retention (T key retained or L non-key retained), any device option (SH shrouded with cut resistant shackle, XSPL cut resistant shackle, or WC weather cover), and chain (M case drilled for a clevis, M1 bronze chain, M5 galvanized steel chain, or none). Settle the core and keying at the same time so the locks arrive on your existing master.
17) Which padlock uses a high-security key system rather than a BEST interchangeable core?
The Sargent 82-856 is a KESO Series non-key retaining padlock with a 2 inch by 2 inch brass case and a stainless steel shackle. The Medeco 5260 uses M3 key technology in a 52 Series brass body. The BEST 41B Series instead runs the standard removable interchangeable core, which is what lets a facility rekey immediately at minimal cost and expand one masterkey system across the BEST line.
