Medeco 54725 Indoor/Outdoor 6-Pin Shrouded Padlock with High Security Cylinder — 7/16" Shackle Diameter, 3/4" Clearance

The Medeco System Series 54725 is a high-security indoor/outdoor shrouded padlock featuring a 6-pin cylinder, a 7/16" shackle diameter, and 3/4" shackle clearance. The padlock is built around a boron alloy steel shackle that resists cutting and pulling attacks while maintaining exceptional ductility. Hardened stainless steel inserts inside the cylinder provide the ultimate defense against drilling and physical attack, and the unique elevating and rotating tumbler pin system is virtually pick-proof. Available in a Black lockbody finish, this padlock is engineered for commercial applications where high security and key control are paramount.

Key Features

  • Shrouded Shackle Protection: The shrouded shackle design provides extra protection against cutting attacks, significantly reducing vulnerability at the shackle.
  • Boron Alloy Steel Shackle: Resists cutting and increased tensile strength resists pulling attacks; exceptional ductility ensures the shackle is not brittle under stress.
  • Shackle Dimensions: 7/16" shackle diameter with 3/4" shackle clearance; available in either 5/16" or 7/16" shackle diameter options across the System Series.
  • Hardened Stainless Steel Cylinder Inserts: Internal hardened stainless steel inserts provide the ultimate defense against drilling, pulling, and other forms of vandal attack.
  • 6-Pin High Security Cylinder: Durable machined brass cylinder components with a unique elevating and rotating tumbler pin system that is virtually pick-proof, designed to last the life of your equipment.
  • Medeco 4 (M4) Key Control: Patented M4 keys may only be duplicated by Medeco or an authorized Medeco service outlet at your request; the Shuttle Pin movable element in the key provides protection against 3D printing and unauthorized duplication.
  • Flexible Keying Options: Locks can be keyed alike, keyed differently, or master keyed with existing door hardware systems to suit specific security needs.
  • Key Retaining Options: System Series padlocks are available as key retaining or non-key retaining configurations.
  • Extended Shackle Availability: Extended shackles available for Indoor/Outdoor padlocks, with a variety of shackle lengths offered across the System Series.

Medeco 5472500-00P – Frequently Asked Questions

1) Will the Medeco 54725 shrouded padlock fit through a standard hasp or chain link?
Check your opening against two numbers before ordering. The 54725 has a 7/16 inch shackle diameter with 3/4 inch shackle clearance, and the shackle width is 7/8 inch. The shroud that protects the shackle from bolt cutters also eats into the space you have to work with, so the hasp staple has to accept a 7/16 inch shackle and the hasp loop or chain link has to sit inside that 3/4 inch of clear opening. If your hasp needs a taller reach, the System Series is offered with extended shackles.
2) Can a Medeco 54725 padlock be keyed into the Medeco master key system already on our building doors?
Yes. The 54725 accepts the same Medeco cylinder technologies used on door hardware, and it can be keyed alike, keyed different, or master keyed into an existing system. You pick the technology and keyway when you order: Original 00, Bilevel DL, M3 DL, Biaxial G3, or Keymark 8E. Match the padlock to whatever generation your building keyway already runs on and one key carries the doors and the padlocks. If you are starting fresh rather than tying into an existing system, order it keyed different or keyed alike as suits the site.
3) What is the difference between key retaining and non-key retaining on a Medeco System Series padlock, and which should I order?
Key retaining means the key will not come out of the cylinder while the lock is open, so the padlock cannot be left hanging unlocked with the key in a pocket. That is what you want on gates, cages, and equipment where the lock must go back on. Non-key retaining lets you pull the key with the shackle open, which suits a lock that gets removed and set aside during the shift. The 54725 is built both ways, and it is a choice you make at the order form, not something you can change later.
4) Is the Medeco 54725 padlock rated for outdoor gates and yard equipment?
It is an indoor/outdoor padlock with a weather resistant design, so exterior gates, fence hasps, storage yards, and outdoor equipment are within what it is built for. Two things carry it outside: the boron alloy steel shackle, which resists cutting and pulling, and the shroud that closes off the shackle to bolt cutters. There is also a stainless steel shackle option if corrosion is the bigger concern at your site than cut resistance, such as coastal or washdown exposure.
5) Should I order the boron alloy steel or the stainless steel shackle on the Medeco 54725?
Pick by the threat. Boron alloy steel is the cut and pull resistant choice, with tensile strength against pulling attacks and enough ductility that it does not go brittle under stress, so it is the one for exposed gates and anything a bolt cutter can reach. Stainless steel is the corrosion answer for wet, salt, or chemical exposure. Both are offered across every keyway and in key retaining and non-key retaining, so you are not giving up a keying option to get the material you need.
6) Is the Medeco 54725 padlock UL listed for high security?
UL 437 Listed, which is the standard covering key resistant locks against picking, drilling, and forcing. Backing that up on the 54725 are hardened stainless steel inserts inside the cylinder that defeat drilling, and the elevating and rotating tumbler pin design that makes it pick resistant. If your spec sheet calls for a UL 437 padlock on a facility, this one answers it.
7) Can anyone get a copy of the key for a Medeco 54725 padlock cut at a hardware store?
No, and that is most of the reason to buy this lock. The M4 keys are patented and may only be duplicated by Medeco or an authorized Medeco service outlet at your request, so a tenant, contractor, or departing employee cannot walk into a store and get a copy. The Shuttle Pin movable element in the key blade also blocks 3D printed and unauthorized copies, since a scanned or photographed key does not reproduce a moving part. For an MRO or property team running a key control program, that is the difference between a padlock and a padlock you can audit.
8) What else could I buy instead of a Medeco 54725, and how are they different?
It depends what the padlock has to do. If you need restricted key control on a commercial building, the closest peers are Sargent's padlocks: the 758 is key retaining, the 858 is non-key retaining with a stainless steel shackle, and the 82-856 is a non-key retaining KESO Series lock with a 2 inch by 2 inch brass case and stainless shackle. If key control is not the point and you are locking out equipment for safety, that is a different product entirely, and the ABUS safety padlocks are what to look at, such as the 72/30 anodized aluminum with a 1-1/4 inch body or the insulated 74/40 with a 6-pin cylinder and 1-1/2 inch body. None of the ABUS safety locks are shrouded, so do not substitute one onto an exterior gate that needs cut resistance.
9) Do I have to specify keyed alike or keyed different when ordering Medeco 54725 padlocks?
Yes, it is a required choice on every order. Keyed alike means every padlock in the batch opens on the same key, which is what a maintenance crew wants when one person carries the ring for thirty gates. Keyed different gives each lock its own key so access is separated by location or by tenant. If you need both, that one key opens everything and each lock stays unique, that is a master key system, and the 54725 can be master keyed alongside your existing Medeco door hardware.
10) What is the closest high-security padlock to the Medeco 54725 if I need a removable core instead of a fixed cylinder?
The Sargent 60-858-2 removable core padlock with a 2 inch stainless steel shackle is the option to look at when the core has to come out for rekeying in the field. The Medeco 54725 is built around a fixed 6-pin high security cylinder with hardened stainless steel inserts and M4 key control, so rekeying runs through the Medeco keying program rather than a core swap. Both are commercial padlocks; the difference is whether your key control program is core-based or cylinder-based.
11) I need a padlock for lockout/tagout, not asset security - is the Medeco 54725 the right part?
For lockout/tagout, the ABUS 72/30 anodized aluminum safety padlock with a 1-1/4 inch body and 3/16 inch shackle is the purpose-built choice, and the ABUS 74/40 insulated safety padlock with a 6-pin cylinder, 1/4 inch shackle and 1-1/2 inch body is the insulated version for electrical work. The Medeco 54725 is a shrouded high-security padlock with a 7/16 inch boron alloy steel shackle and M4 key control, aimed at resisting cutting, drilling and picking on secured assets rather than at personnel isolation.
12) Which padlock should I use if the hasp needs a taller shackle than the Medeco 54725 gives me?
The Medeco 54725 has 3/4 inch of shackle clearance under a 7/16 inch diameter shackle, which is tight on thick hasps and chain. The Sargent 60-858-2 carries a 2 inch stainless steel shackle, which is the peer to specify when the shackle has to reach through a larger hasp or a chain link. Measure the stack the shackle must pass through before committing either way.
13) I have to keep key retention consistent across a facility - which padlocks give me both retaining and non-retaining options?
The Medeco 54725 is ordered as either key retaining or non-key retaining across its keyway range, so both behaviors come from one part family. On the Sargent side those are separate part numbers: the Sargent 758 is a key retaining standard padlock in US4 satin brass, and the Sargent 858 is the non-key retaining version with a stainless steel shackle in the same finish. Specify which behavior each opening needs before you standardize, since padlocks left hanging on an open hasp need the non-retaining version.
14) Which other padlock uses a patented restricted key system like the Medeco 54725?
The Sargent 82-856 is a KESO Series non-key retaining padlock with a 2 inch by 2 inch brass case and stainless steel shackle, and KESO is Sargent's restricted key platform. The Medeco 54725 runs Medeco 4 (M4) key control, where keys are duplicated only by Medeco or an authorized Medeco service outlet at your request. The two are separate key systems, so pick the one that matches the restricted keyway your facility already runs; the 54725 is also offered in Original 00, Bilevel DL, Keymark 8E, M3 DL and Biaxial G3 keyways for tying into an existing Medeco program.
15) What does Pinned versus Sub-Assembled mean when ordering a Medeco padlock?
Pinned ships with the cylinder already combinated to a key, ready to hang. Sub-Assembled ships with the cylinder unpinned so a locksmith or an in-house key control shop pins it to your own system, which is how facilities with a Medeco master key program usually buy them. If you do not run your own pinning bench, order Pinned. Every keyway on the 54725, Original 00 through Biaxial G3, is offered both ways.
16) How many pins does the Medeco 54725 cylinder have and does that matter for master keying?
Six pins. That matters when you are building or extending a master key system, because pin count sets how many usable change key combinations sit under a master, and a 6-pin cylinder gives a much deeper system than a 5-pin one before you start running out. Combine that with the elevating and rotating tumbler design and each of those six positions carries more than one variable, which is the source of both the pick resistance and the system depth.
17) Can I swap out just the cylinder in a Medeco 54725 the way I would on an interchangeable core padlock?
No. The 54725 is a pinned cylinder padlock, not a removable core design, so rekeying means pinning the cylinder rather than pulling a core with a control key. If your program is built on swapping cores in the field, a removable core padlock such as the Sargent 60-858-2 is the format that matches that workflow. Where the 54725 does give you flexibility is at order time: buy it Sub-Assembled and your locksmith pins it into your own system before it ever reaches the site.
18) Is a Schlage KS23D a substitute for a Medeco 54725?
The Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle, so it is a smaller-shackle brass-body lock. The Medeco 54725 uses a 7/16 inch shackle in boron alloy steel or stainless steel and a shrouded body that covers the shackle shoulders. If the specification calls out shrouded construction or the 7/16 inch shackle, the Schlage is a different part rather than a drop-in.
19) What is the alternative to the Medeco 54725 if I need a padlock that will not mar a painted or finished surface?
The ABUS 76/40 plastic-covered aluminum core padlock, 1/4 inch shackle diameter and 1-37/64 inch width, and the ABUS T84MB/30 Nautic black sleeve padlock, 13/64 inch shackle and 1-17/64 inch body, both carry a covering over the body for that reason. The Medeco 54725 is a bare shrouded metal body in a black lockbody finish with a 7/16 inch shackle, built for attack resistance rather than surface protection.
20) Can I put a Sargent 858 on the same key system as a Medeco 54725?
No - they are different keying platforms. The Sargent 858 is a non-key retaining padlock with a stainless steel shackle in US4 satin brass on the Sargent 858 Series, while the Medeco 54725 is keyed on Medeco cylinders and can be keyed alike, keyed differently or master keyed into an existing Medeco system. If the goal is one key across the padlocks and the door hardware, stay on whichever platform the doors already use.
21) What finish does the Medeco 54725 padlock body come in?
Black is the lockbody finish. There is no second body color to choose, so if you are standardizing padlocks across a campus and want them visually consistent, every 54725 will match regardless of which keyway, shackle material, or key retention you order it with.
