Sargent F1-82-857 – Frequently Asked Questions

1) Will a Sargent KESO F1 padlock work on my existing Sargent master key system?
The F1-82-857 padlock keys into an existing KESO F1 key system, so it can be masterkeyed alongside the door locks already running on that system. That is the point of buying it over a hardware-store padlock: one key opens the gate, the cage, and the doors. Keying is a required choice when you order, keyed different or keyed alike, and you can specify the keyway. If your facility is not on a KESO F1 system, a padlock on its own key is the simpler buy.
2) How much shackle clearance do I get on the Sargent F1-82-857 padlock, and what do I order for a thick hasp?
Three shackle clearances: 1 inch standard, 2-1/2 inch (order as 857-2), and 4 inch (order as 857-4). Measure the stack you are locking through, hasp thickness plus chain link or lug, and pick from there. A 1 inch clearance is fine on a standard hasp staple but will not reach around a chain or a doubled cable. The 4 inch is what you want for gate chain.
3) What does key retaining mean on a padlock, and is it the right choice for my building?
Key retaining means the key will not come out of the cylinder unless the padlock is locked. On the F1-82-857 you cannot walk off with the key while the lock hangs open on the hasp, which is exactly what you want on a fire pump room, a roof hatch, or a tenant storage cage where an open lock left unlocked is the failure. It is the wrong feature for lockout/tagout style use where a technician wants to pocket the key with the lock open. For that, a non-key-retaining padlock like the Medeco 54515G is the type to look at.
4) Do I have to specify keying when ordering the Sargent F1-82-857 padlock?
Yes, keying is a required selection. Choose keyed different, so every padlock has its own key, or keyed alike, so a group of padlocks all open on the same key. Keyed alike is what most property managers want for a run of storage units or gates on one property. You can also specify the keyway, which is how the padlock gets pinned into your existing KESO F1 system rather than shipping on a standalone key.
5) What is the closest brass-body padlock to the Sargent F1-82-857 if the facility is not on a KESO F1 key system?
The Medeco 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter, built on M3 key technology and finished in satin chrome. It is the nearest brass-cased peer to the Sargent F1-82-857, which carries a 2 x 2 x 1-1/8 inch brass case in US4 satin brass with an 11/32 inch stainless steel shackle. The Sargent is keyed into a KESO F1 system, so a locksmith standardizing on Medeco M3 cylinders would go to the 5260, while a site already running KESO F1 keeps the Sargent so the padlock keys to the same system as the doors. Note the shackle diameters differ: 7/16 inch on the Medeco against 11/32 inch on the Sargent, which changes what hasp or chain link it will pass through.
6) Is the Schlage KS23D a direct replacement for a Sargent F1-82-857 padlock?
Not directly. The Schlage KS23D/KS23F is a 20 Series brass padlock with a 5/16 inch diameter shackle; the Sargent F1-82-857 has a brass case measuring 2 x 2 x 1-1/8 inch with an 11/32 inch stainless steel shackle and is keyed into the KESO F1 system. Both are brass-bodied commercial padlocks, so they suit similar gate, cabinet, and hasp duty, but the shackle diameters are different and the key systems are different, so a KS23D will not operate on a KESO F1 key. A property manager replacing one padlock in a mixed set can use either; one standardizing a whole property on a single key should stay within one system.
7) What padlock should I use instead of the Sargent F1-82-857 for lockout/tagout on electrical equipment?
For lockout/tagout, look at the ABUS 72/30 anodized aluminum safety padlock with a 1-1/4 inch body width and 3/16 inch shackle diameter, or the ABUS 74/40 insulated safety padlock with a 6-pin cylinder, 1/4 inch shackle diameter, and 1-1/2 inch body width. Both are lighter-bodied safety padlocks in smaller body widths than the Sargent F1-82-857, which is a 2 x 2 x 1-1/8 inch solid brass case with an 11/32 inch stainless steel shackle. The 74/40 is the insulated one, which is what an electrical contractor asks for when the lock may contact energized gear. The Sargent stays the choice where the padlock has to key into an existing KESO F1 master key system.
8) What is the difference between the Sargent F1-82-857 and the Medeco 54515G XT padlock?
They solve access control two different ways. The Medeco 54515G XT is an electronic indoor/outdoor padlock supplied with cylinder, and it is non-key retaining with a 5/16 inch shackle diameter. The Sargent F1-82-857 is mechanical and key retaining, meaning the key comes out only in the locked position, and it operates on the KESO F1 mechanical master key system. Non-key retaining means the key can be withdrawn while the padlock is open, which some crews prefer and some facilities specifically prohibit. An integrator building audit trails and scheduled access goes electronic with the 54515G; a facility that wants the padlock on the same brass key as its doors stays with the Sargent.
9) Is the Sargent F1-82-857 padlock OK outdoors on a gate or yard fence?
Built for it. The case is solid brass and the shackle is stainless steel, neither of which rusts through the way a plated steel padlock does, and the padlock ships with standard rubber shields that keep water off the shackle so it does not freeze shut. That is the combination that matters on an exterior gate through a winter.
10) Can I get a Sargent KESO padlock with a chain attached?
Yes, the F1-82-857 is offered chained or unchained, and the chain option is available with every shackle length, 1 inch, 2 inch and 4 inch, in both stainless steel and hardened steel. The chain keeps the padlock captive on the gate or the panel so it does not end up in a truck box or on the ground, which is the usual reason a maintenance crew loses one.
11) Should I order the stainless steel or the hardened steel shackle?
Both are offered across all three shackle lengths on the F1-82-857. Stainless is the corrosion answer, exterior gates, coastal sites, wash-down areas, anything that sees weather year round. Hardened steel is the cut resistance answer, for a padlock that is exposed to attack more than to water. Indoors on a cage or an electrical enclosure, hardened steel is the sensible pick; outside on a fence line, stainless.
12) What else could I use instead of a Sargent KESO padlock for a commercial site?
Depends on what you are giving up. If you do not need KESO F1 keying, the Medeco 5260 is a brass body padlock with a 7/16 inch shackle in satin chrome, a heavier shackle than the 11/32 inch on the Sargent. The Schlage KS23D/KS23F is another brass padlock, 5/16 inch shackle. For safety and utility work rather than security, the ABUS 72/30 anodized aluminum safety padlock has a 1-1/4 inch body and a 3/16 inch shackle, and the ABUS 74/40 is insulated with a 6-pin cylinder and a 1/4 inch shackle. None of those key into a KESO F1 system, which is the whole reason to buy the Sargent.
13) Which padlock holds up better than the Sargent F1-82-857 on an exposed coastal or wash-down location?
The Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less the pop-out cylinder, and the ABUS T84MB/30 Nautic uses a black sleeve over the body with a 13/64 inch shackle diameter and 1-17/64 inch body width. Both are built for wet, salt-air exposure. The Sargent F1-82-857 handles outdoor duty with a solid brass case and standard rubber shields that protect the shackle from freezing, and its shackle is stainless steel at 11/32 inch. The split is straightforward: choose the Sargent when the padlock must key into the site's KESO F1 system, and the Medeco 521 G8R when you want an all stainless steel body and are supplying the cylinder separately.
14) Is there a lighter padlock than the Sargent F1-82-857 for lockers and light cabinet duty?
The ABUS 76/40 is a plastic-covered aluminum core padlock with a 1/4 inch shackle diameter and 1-37/64 inch width, and the ABUS 72/30 is anodized aluminum at 1-1/4 inch body width with a 3/16 inch shackle. Both use aluminum cores rather than the solid brass case of the Sargent F1-82-857, which measures 2 x 2 x 1-1/8 inches with an 11/32 inch stainless steel shackle and dual stainless steel ball locking. The plastic cover on the 76/40 is the one to reach for where the padlock swings against a painted or finished surface. Where the padlock has to be on the building master key, the Sargent is the one that integrates.
15) I need a padlock with a long shackle for a chain link gate - does the Sargent F1-82-857 do that or do I need a different lock?
The Sargent F1-82-857 covers it without changing products. It is offered in 1 inch, 2 inch, and 4 inch shackle lengths, in stainless steel or hardened steel, with or without a chain, and the description calls out 2-1/2 inch clearance as 857-2 and 4 inch clearance as 857-4. Among the peers, the Medeco 5260 brass body padlock carries a heavier 7/16 inch shackle diameter and the Medeco 521 G8R has a solid stainless steel body, but the long-clearance requirement is what the 857 shackle options are for. Order the 4 inch shackle with the chain option if the padlock needs to stay captive to the gate.
16) Can I order the Medeco 521 G8R and key it to my system the same way as the Sargent F1-82-857?
They are ordered differently. The Medeco 521 G8R is supplied less the pop-out cylinder, so the cylinder is a separate line and the keying is decided by the cylinder you install. The Sargent F1-82-857 is ordered with the keying specified on the padlock itself, keyed different or keyed alike, with the keyway called out, and it integrates into an existing KESO F1 master key system. For a distributor quoting a job, that is two line items on the Medeco and one on the Sargent.
17) What finish does the Sargent F1-82-857 padlock come in?
US4 satin brass, and it is the only finish offered. On a padlock that finish is really about the case material, solid brass, rather than matching door trim, but if you are standardizing a facility on US4 hardware it lines up.
18) What makes a commercial padlock harder to pop than a hardware store one?
Two things on the Sargent F1-82-857. The case uses positive deadlocking construction with no springs in the locking path, so there is nothing to force or shim. And the shackle is held by dual stainless steel balls, a design where pulling harder on the shackle drives the balls tighter rather than loosening them. That is the difference between a padlock that resists a pry bar and one that comes off with a slide hammer.
19) I need a padlock for a marine or coastal application, is brass the right body?
The Sargent F1-82-857 gives you a brass case with a stainless shackle, which holds up outdoors, but it is a keyed-system padlock first. If the driver is purely salt exposure and you do not need KESO keying, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, and the ABUS T84MB/30 Nautic is a sleeved padlock with a 13/64 inch shackle and a 1-17/64 inch body for smaller marine hardware.
