Medeco 5260 52 Series Brass Body Padlock with 7/16" Shackle Diameter and M3 Key Technology — Satin Chrome Finish

The Medeco 52 Series Brass Body Padlock delivers professional-grade security with a 7/16" shackle diameter and advanced M3 Key Technology, available exclusively in Satin Chrome (26) finish. Designed to be keyed with Medeco's 60 Series cam locks and switch locks, this padlock features a brass case construction with a choice of stainless steel shackles for corrosion protection or hardened boron alloy steel shackles for resistance against cutting, sawing, and prying. UL listed cylinders and cores make this padlock virtually pickproof and drill proof, while patented key control prevents unauthorized key duplication — making it an ideal solution for demanding commercial and industrial applications both indoors and outdoors.

Key Features

  • 7/16" Shackle Diameter: Robust shackle sizing engineered for high-security commercial and industrial applications requiring strong physical resistance.

  • Protection from Shackle Attack: Hardened boron alloy steel shackles provide strong resistance against cutting, sawing, and prying; stainless steel shackle option protects against corrosion.
  • Toe and Heel Deadbolt Locking Action: Dual-point locking mechanism provides superior resistance to shackle attack and forced entry attempts.
  • Pickproof and Drill Proof Cylinders: UL listed cylinders and cores resist drilling, picking, bumping, and other forms of physical attack through cylinder side pins, a lift pin, and a movable key element engaging a sidebar.
  • Keyed with 60 Series Locks: The 52 Series is specifically designed to be keyed with Medeco's 60 Series cam locks and switch locks for unified key system management.
  • Versatile Keying Options: Available keyed differently, keyed alike, or master keyed to meet specific operational needs; available in non-key retained or key retained functions.
  • Optional Dust Cover: Protects the keyway of the cylinder from weather conditions, extending service life in outdoor environments.

Medeco 526201T – Frequently Asked Questions

1) Will a Medeco 52 Series padlock fit through a hasp with a 1-1/8 inch opening, or do I need more clearance?
The 5260 brass body padlock is offered in two shackle clearances, 1-1/8 inch and 1-7/8 inch. Take the 1-1/8 inch for a standard hasp or a cabinet staple where the shackle only has to pass through a thin loop. Go to 1-7/8 inch when you are locking a chain link gate, a thick hasp with a backing plate, or wrapping a chain, since the shorter clearance will not close over the extra material. The shackle diameter is 7/16 inch on either one, so the hasp eye has to accept that thickness.
2) Boron alloy or stainless steel shackle on a Medeco 52 Series padlock, which should I order?
Pick by the threat, not the location. Hardened boron alloy steel resists cutting, sawing, and prying, so it is the one for gates, cargo doors, and anywhere a bolt cutter is the realistic attack. Stainless steel trades some of that for corrosion protection, which matters on coastal sites, wash-down areas, and anything permanently exposed to weather. Both are offered in the 1-1/8 inch and 1-7/8 inch clearances, so shackle material and length are separate decisions.
3) Can Medeco 52 Series padlocks be keyed into the same system as my existing Medeco cam locks?
Yes, and that is the reason to spec them. The 52 Series is built to be keyed with Medeco's 60 Series cam locks and switch locks, so a facility running Medeco cams on cabinets, panels, and vending equipment can put the same key on its padlocks. The 5260 uses M3 key technology and can be master keyed into a system containing Medeco 4 (M4), X4, and M3 CLIQ, which is what lets you add these to an existing Medeco master key system rather than starting a second one.
4) What do I have to specify when ordering a Medeco 5260 padlock?
Four things. Shackle clearance, 1-1/8 or 1-7/8 inch. Shackle material, boron alloy or stainless. Keying, keyed different or keyed alike (master keying is also available). And whether you want the optional dust cover, which shields the keyway from weather on outdoor mountings. Finish is not a decision here, the 5260 is satin chrome (26) only. The 52 Series is also offered in non-key retained or key retained function, key retained meaning the key will not come out while the lock is open.
5) Can a tenant or employee get a Medeco 52 Series key copied at the hardware store?
No. Medeco key control is patented and the blanks are restricted, and the angled key cuts require a special key cutting machine, so a hardware store or a big box counter cannot duplicate one. Restrictions are available at various levels. That is the practical reason property managers and MRO buyers move to Medeco on mechanical rooms, roof access, and telecom closets, keys stop leaking into circulation.
6) I need padlocks for electrical lockout tagout, is the Medeco 5260 the right choice?
No. The 5260 is a security padlock with a brass body and a metal shackle, meant to stop attack, not to insulate. For lockout tagout use a safety padlock instead: the ABUS 74/40 insulated safety padlock with a 6 pin cylinder, 1/4 inch shackle and 1-1/2 inch body, or the ABUS 76/40 plastic covered aluminum core padlock with a 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 personal locks on a group lockout.
7) Which brass case padlock should I standardize on across a facility if I want one keying program for padlocks and cabinet locks?
The Medeco 5260 is built for that: it is a brass body padlock using M3 key technology that can be keyed with Medeco 60 Series cam locks and switch locks, and it can be master keyed into a system containing Medeco 4, X4 and M3 CLIQ, so padlocks, cabinets and switch locks answer to one hierarchy. It ships keyed different or keyed alike. Among the brass case comparables, the Sargent 82-856 is a non-key retaining padlock with a 2 inch by 2 inch brass case and a stainless steel shackle in the KESO series, which is the choice when the site is standardizing on a KESO program instead. The deciding question is which key system the rest of the building already runs.
8) What is the closest brass-body high-security padlock to the Medeco 5260 if a 7/16 inch shackle is too heavy for the hasp?
The Medeco 5260 is a brass body padlock with a 7/16 inch shackle diameter, which is the largest shackle in this comparison and needs a hasp opening sized for it. Where the hasp will not take 7/16 inch, the Schlage KS23D/KS23F is also a brass padlock and uses a 5/16 inch diameter shackle, so it passes through a narrower hasp eye while keeping a brass case. Confirm the hasp opening before choosing between them, since a shackle that will not seat in the staple is the usual reason a padlock gets returned.
9) I need padlocks that drop into an existing interchangeable core keying program instead of a Medeco M3 system. What should I order?
The Medeco 5260 uses Medeco M3 key technology and is built to key together with Medeco 60 Series cam locks and switch locks, so it belongs to a Medeco keyway program. If the facility is already standardized on removable cores from another program, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, so the core comes out and gets keyed to the existing system rather than the padlock dictating the keyway. Decide by which key system the site is committed to, not by the padlock body.
10) Is a Medeco 5260 padlock UL listed, and what does that cover?
UL 437 Listed applies to the M4 cylinders, covering resistance to drilling, picking, and physical attack. The 52 Series uses UL listed cylinders and cores, with cylinder side pins, a lift pin, and a movable key element engaging a sidebar doing the work. For a spec that calls out a high security cylinder by standard, that is the citation you want on the submittal.
11) My facility uses small format interchangeable cores so I can rekey in house. Does the Medeco 5260 do that?
The 5260 is a fixed cylinder padlock on the Medeco M3 platform, keyed different, keyed alike, or master keyed to your system when it ships. If your program depends on pulling and swapping cores on site, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle and is the one to look at. Where the priority is instead key control that survives a lost key, the Medeco M3 cylinder with restricted blanks is the stronger answer.
12) Will a Medeco 52 Series padlock hold up outdoors on a perimeter gate?
It is built for it. Brass case in a satin chrome plated finish handles outdoor exposure, and the stainless steel shackle option adds corrosion protection where salt or constant wet is the issue. Add the optional dust cover to keep weather out of the keyway, which is what usually kills an outdoor padlock long before the body does. Perimeter gates and fencing are a named application for the 52 Series, along with cargo vehicles and industrial storage.
13) What stops someone from just prying the shackle out of a Medeco 5260 padlock?
Toe and heel deadbolt locking. The shackle is bolted at both legs rather than one, so pulling or twisting one side does not release it, and there is no single shear point to attack. Combined with the 7/16 inch hardened boron alloy shackle option, that covers the two common field attacks, cutting the shackle and prying the body off it.
14) What is the difference between a key retaining and non-key retaining padlock, and which comparable padlocks are which?
Key retaining means the key cannot be withdrawn while the padlock is open, so the lock cannot be left hanging unlocked with the key in a pocket. The Medeco 5260 52 Series is offered in both non-key retained and key retained functions. Among the Sargent comparables, the 758 is a key retaining standard padlock in a US4 satin brass finish, while the 858 is non-key retaining with a stainless steel shackle in the same US4 satin brass finish. Gates and cargo doors that must never be left open are the usual case for key retaining; a padlock that gets removed and carried is the usual case for non-key retaining.
15) Are ABUS safety padlocks an equivalent substitute for a Medeco 52 Series padlock?
They serve 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, and the ABUS 74/40 is an insulated safety padlock with a 6-pin cylinder, a 1/4 inch shackle and a 1-1/2 inch body. Safety padlocks in that class are sized for lockout and tagout on energy isolation points, where the padlock marks a device as locked out and one worker holds the key. The Medeco 5260 is a brass body padlock with a 7/16 inch shackle and toe and heel deadbolt locking action for physical attack resistance on gates, cargo and storage. Ordering one where the other is specified leaves either a lockout program without its rated padlock or an exposed gate under a light shackle.
16) For a coastal or marine installation, what are the corrosion options across these padlocks?
The Medeco 5260 has a brass case in a satin chrome 26 finish and is offered with a stainless steel shackle specifically for corrosion protection, with a boron alloy shackle as the alternative when cut resistance matters more; an optional dust cover shields the keyway from weather. If the exposure is salt spray on lighter duty hardware, the ABUS T84MB/30 Nautic is a black sleeve padlock with a 13/64 inch shackle diameter and a 1 17/64 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. Match the shackle diameter to the hasp first, then pick the corrosion treatment.
17) The hasp clearance on my gate is 1-7/8 inches. Which of these padlocks covers that, and what if I need a longer reach?
The Medeco 5260 comes in 1-1/8 inch and 1-7/8 inch clearance sizes, each available with a boron alloy or stainless steel shackle, so a 1-7/8 inch clearance gate is covered directly. If the reach needed is longer than that, the Sargent 60-858-2 is a removable core padlock built with a 2 inch stainless steel shackle. Measure the stack the shackle has to clear, chain link included, before committing to a clearance.
18) Key retained or non key retained padlock, which one do I want for my crew?
Key retained holds the key captive while the lock is open, so the key cannot walk away or get pocketed with the lock hanging unlocked. That is the one for shared gates, delivery bays, and anywhere a rotating crew is expected to relock. Non key retained lets the key come out either way, which suits a single keyholder who locks and moves on. The Medeco 52 Series is offered in both functions. Among comparable brass padlocks, the Sargent 758 is key retaining and the Sargent 858 is non key retaining.
