Sargent 82-857 – Frequently Asked Questions

1) Will the Sargent 82-857 padlock work on my existing key system, or does it need KESO keys?
The Sargent 82-857 is built only for KESO key systems. It works with KESO F1 and standard KESO keys, and it can be master keyed along with the rest of the locks in that system. If your building is keyed in a conventional Sargent keyway or any non-KESO system, this padlock will not take your key and you need a different padlock.
2) What shackle clearances can I get on the Sargent 82-857 KESO padlock?
Three clearances: 1 inch standard, 2-1/2 inch (ordered as 857-2), and 4 inch (ordered as 857-4). Measure the hasp, chain link, or gate loop you are locking through before you pick. The 1 inch is fine for a standard staple hasp; go to 2-1/2 or 4 inch when you need to pass through a heavy chain or a thick gate fitting.
3) What does key retaining mean on this Sargent padlock, and is that what I want?
Key retaining means the key only comes out when the padlock is locked. On the 82-857 you cannot walk away with the key while the lock is hanging open, which is why facilities use it on gates, cages, and storage where an open padlock left unlocked is the real risk. If your crew needs to pull the key with the lock open (lockout/tagout style use), a non key retaining padlock such as the Medeco 54515G XT is the other approach.
4) What do I have to specify when ordering the Sargent 82-857 padlock?
Four things. Shackle clearance (1 inch, 2 inch, or 4 inch), shackle material (stainless steel or hardened steel), whether you want the chain attachment, and the keying. Keying is a required choice of keyed different or keyed alike, and you can supply the keyway for your KESO system. The chain option ships with a 9 inch chain, ordered as 857C.
5) Can I standardize padlocks across a whole facility with the Sargent 82-857?
That is what it is for. Because it runs on KESO, the padlocks can be master keyed into the same system as your door cylinders, so one master opens the gates, cages, and doors. Order keyed alike if groups of padlocks should share a key, keyed different if each needs its own. This is a commercial product line.
6) I need a high-security padlock but I am not on a KESO system. What else can I use?
Since the Sargent 82-857 only accepts KESO keys, look at a different platform. The Medeco 5260 is a brass body padlock on Medeco M3 key technology with a 7/16 inch shackle. The Medeco 521 G8R is a weather-tight solid stainless steel body padlock supplied less the pop-out cylinder, so you fit your own. For lower-security or safety-lockout use, the ABUS 76/40 plastic-covered aluminum core padlock is a lighter option.
7) What is the closest brass-body padlock to the Sargent 82-857 if the site is not on a KESO key system?
The Sargent 82-857 has a solid brass case measuring 2 inches by 2 inches by 1-1/8 inches with an 11/32 inch stainless steel shackle, and it is built specifically for KESO F1 and standard KESO key systems, so it keys into a KESO master key system and nothing else. If the facility runs a different key system, the Medeco 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter and M3 key technology in a satin chrome finish, and the Schlage KS23D/KS23F is a brass padlock with a 5/16 inch shackle diameter. Both give you a brass body in the same class; the keying is what decides which one belongs on the gate.
8) What should I use instead of the Sargent 82-857 on an electrical lockout or tagout application?
The Sargent 82-857 is a key retaining brass padlock for KESO key systems, where the key comes out only in the locked position, which is the opposite of what a personal lockout lock needs. For lockout and tagout work, the ABUS 74/40 is an insulated safety padlock with a 6-pin cylinder, a 1/4 inch shackle diameter and a 1-1/2 inch body width, and the ABUS 76/40 is a plastic-covered aluminum core padlock with a 1/4 inch shackle and a 1-37/64 inch width. The ABUS 72/30 anodized aluminum safety padlock has a 1-1/4 inch body width and a 3/16 inch shackle for lighter duty.
9) I need a padlock that can be opened and closed without the key staying captive. Is the Sargent 82-857 the wrong lock?
Yes, if the user has to walk away with the key while the lock is open. The Sargent 82-857 is a key retaining padlock, so the key is removable only when the padlock is locked. A non-key-retaining alternative is the Medeco 54515G XT electronic indoor/outdoor padlock, which is listed as non-key retaining with a 5/16 inch shackle diameter and ships with a cylinder. Choose the 82-857 when you want positive proof the lock was re-secured before the key came out.
10) Can the Sargent 82-857 be master keyed with the rest of my locks the way a Medeco padlock can?
The Sargent 82-857 can be master keyed with all locks in a KESO security system, since it is built for KESO F1 and standard KESO keyways, and it is ordered keyed alike or keyed different with the keyway specified. The Medeco 5260 brass body padlock instead runs M3 key technology, and the Medeco 521 G8R accepts a pop-out cylinder that is supplied separately. In practice the 82-857 only joins a master key system that is already KESO; a Medeco padlock joins a Medeco system.
11) Will the Sargent 82-857 hold up outdoors in winter?
It is built for it. The case is solid brass and the shackle is stainless steel, and the shackle carries rubber shields to keep it from freezing up. Brass and stainless is the combination you want on an exterior gate or yard application where a plated steel body would rust.
12) How big is the Sargent 82-857 padlock body?
The brass case measures 2 x 2 x 1-1/8 inches. That is a commercial size footprint, so check that your hasp plate has room for a 2 inch wide body before ordering, particularly on recessed or shrouded hasps.
13) What shackle diameter is the Sargent 82-857, and how does it compare to other commercial padlocks?
The shackle is 11/32 inch stainless steel. For reference against other padlocks we carry: the Schlage KS23D/KS23F brass padlock uses a 5/16 inch shackle, the Medeco 5260 brass body padlock uses 7/16 inch, and the ABUS 74/40 safety padlock uses 1/4 inch. Bigger diameter resists cutting better but needs a larger hasp eye to pass through.
14) Stainless steel or hardened steel shackle on the Sargent 82-857?
Both are offered across all three shackle lengths. Stainless is the choice for exterior and corrosive environments, coastal sites, wash-down areas, and anywhere the lock sits in the weather. Hardened steel trades some corrosion resistance for cut resistance and is the pick for interior or covered high-security use.
15) What keeps the shackle locked on the Sargent 82-857, and how does it resist attack?
Two stainless steel balls lock the shackle, and the mechanism is positive deadlocking with no springs to force. Pulling on the shackle increases the locking action rather than relieving it. That matters on gates and perimeter hardware where a pry bar or a jerk on the shackle is the likely attack.
16) Is there a heavier shackle option than the Sargent 82-857 padlock?
The Sargent 82-857 uses an 11/32 inch diameter stainless steel shackle, with two stainless steel balls locking the shackle and a positive deadlocking design that uses no springs. If you want a thicker shackle, the Medeco 5260 lists a 7/16 inch shackle diameter on a 52 Series brass body. The Sargent stays the choice where the padlock has to key into a KESO system and where the rubber shackle shields matter for outdoor freeze protection.
17) For a coastal or wash-down location, is the Sargent 82-857 the right padlock or is there a better body material?
The Sargent 82-857 pairs a solid brass case with a stainless steel shackle protected by rubber shields to prevent freezing outdoors, and its substrate is listed as stainless steel. Where you want the entire body in stainless rather than brass, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less the pop-out cylinder. The ABUS T84MB/30 Nautic is a black sleeve padlock with a 13/64 inch shackle diameter and 1-17/64 inch body width for marine use, though at a much smaller body than the 2 inch by 2 inch Sargent.
18) I need extra shackle clearance for a thick hasp. Does the Sargent 82-857 cover that or do I need a different padlock?
The Sargent 82-857 covers it directly. Beyond the 1 inch standard clearance it is available with 2-1/2 inch clearance ordered as 857-2 and 4 inch clearance ordered as 857-4, and a chain attachment with a 9 inch chain is available as 857C. Among the alternatives, shackle sizes such as the 5/16 inch on the Schlage KS23D/KS23F or the 7/16 inch on the Medeco 5260 describe diameter rather than clearance, so the Sargent tall-shackle options are the straightforward answer for a deep hasp.
19) Should I get the chain version of the Sargent KESO padlock?
Take the chained version when you do not want the lock lying on the ground or going missing once it is opened. It comes with a 9 inch chain, ordered as 857C, so the padlock stays tethered to the gate, cabinet, or cage it secures. Every shackle length we offer, 1 inch, 2 inch, and 4 inch, can be had with or without the chain.
20) What finish does the Sargent 82-857 padlock come in?
US4 satin brass, which is the natural finish of the solid brass case. If you are matching a set of padlocks across a property, they will all read the same warm brushed brass tone rather than the chrome or anodized look of alternatives like the Medeco 5260 in satin chrome or the ABUS 72 Series anodized aluminum safety padlock.
