American Lock AME-A3571WOUN 2KEY – Frequently Asked Questions

1) Does the American Lock A3571WOUN padlock come with a core or keys?
No core. The A3571WOUN ships as a brass padlock body without a cylinder, and it is uncombinated, meaning you supply and pin the small format interchangeable core yourself. Key counts you see on the order are the keys that go with the core you have keyed up, not a factory-cut set for the lock.
2) What are the body and shackle dimensions on the A3571WOUN padlock?
The body is 2 inches wide in solid brass. The shackle is 3/8 inch diameter with a 2 inch shackle length and 3/4 inch clearance between the legs, so measure your hasp eye and staple spacing against those two numbers before ordering.
3) I need a brass padlock that arrives ready to use with its own cylinder instead of one I have to core. What should I order?
The A3571WOUN ships without a cylinder and uncombinated, so it needs a small format interchangeable core before it will operate. If you want a brass-body padlock supplied with a keyed cylinder, the Sargent 758 is a key-retaining padlock in a US4 satin brass finish, the Sargent 858 is the non-key-retaining version with a stainless steel shackle in the same US4 satin brass, and the Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle. The Medeco 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter and M3 key technology in satin chrome.
4) What else could I use instead of the American Lock brass SFIC padlock if I do not run an interchangeable core system?
If you are not pinning your own cores, a conventional brass-body padlock is simpler. The Schlage KS23D/KS23F is a brass padlock with a 5/16 inch shackle diameter, and the Sargent 758 is a key retaining brass padlock in a US4 satin brass finish. If you want removable core but a different platform, the Sargent 60-858-2 removable core padlock has a 2 inch stainless steel shackle. The American Lock is the one to choose specifically when you want the lock on the same SFIC keyway as your doors.
5) Is a brass padlock the right choice for coastal or wash-down locations?
That is the reason to pick brass over a steel or laminated body. The solid brass case resists corrosion in salty, caustic and wet environments, which is why this one is put on marine and offshore gear, utility equipment and tool cribs. The shackle is hardened boron alloy steel for cut resistance, so you are not giving up shackle strength to get the corrosion performance.
6) Can I get this American Lock padlock with a chain so it stays attached to the gate?
Yes. It can be ordered with a #40 sash chain, 9 inches long, zinc plated, or with no chain at all. The chain option keeps the padlock captive on a hasp or gate so it does not walk off when the lock is opened.
7) What is the difference between the A3571WOUN and the A3571WOKA or A3571WOMK?
Same 2 inch solid brass SFIC padlock body in every case; the suffix tells the factory how to key it. UN is uncombinated, so no core and no keying is done. KD is keyed different, KA is keyed alike across the group, MK is keyed different under a master key, and KAMK is keyed alike under a master key. Buy UN when your locksmith or in-house shop pins the cores to your existing system.
8) The A3571WOUN is being used on a marine dock. Is there a more weather-specific padlock to consider?
The A3571WOUN uses a solid brass body specifically for corrosion resistance in caustic, corrosive and salty environments, which is why it is positioned for marine and offshore security. If you want a non-brass alternative built for exposure, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body supplied less pop-out cylinder, so it also takes a cylinder separately. The ABUS T84MB/30 Nautic is a sleeve-covered padlock with a 13/64 inch shackle diameter and 1-17/64 inch body width, a much lighter build than the 2 inch brass body.
9) Can I use an ABUS safety padlock in place of the American Lock A3571WOUN for a tool crib?
They are built for different jobs. The A3571WOUN is a 2 inch wide solid brass body with a 3/8 inch hardened shackle and a small format interchangeable core cavity, so it keys into the same system as your door locks. The ABUS 72/30 is an anodized aluminum safety padlock with a 1-1/4 inch body and 3/16 inch shackle, the ABUS 74/40 is an insulated safety padlock with a 6-pin cylinder, 1/4 inch shackle and 1-1/2 inch body, and the ABUS 76/40 is a plastic-covered aluminum core padlock with a 1/4 inch shackle and 1-37/64 inch width. Those are lighter lockout/tagout style bodies with fixed cylinders, not core-ready security padlocks.
10) We are moving to electronic audit-trail access control. Is there a padlock alternative to the A3571WOUN?
The A3571WOUN is a mechanical padlock that accepts a small format interchangeable core and comes uncombinated, so access is controlled by your key system. If you need electronic credential control instead, the Medeco 54515G XT is an electronic indoor/outdoor padlock, non-key-retaining, with a 5/16 inch shackle diameter and supplied with cylinder. It replaces mechanical keying rather than joining your existing SFIC system.
11) Which alternatives match the 2 inch shackle length of the American Lock A3571WOUN?
The A3571WOUN has a 2 inch shackle length with a 3/8 inch diameter and 3/4 inch shackle width. Among the peers, the Sargent 60-858-2 is specified with a 2 inch stainless steel shackle, making it the direct match on shackle height, and it is likewise a removable core design. The Schlage KS23D/KS23F brass padlock and the Medeco 54515G run 5/16 inch shackle diameters, and the Medeco 5260 runs 7/16 inch, so confirm the hasp clearance before you swap.
12) How many of these padlocks come in a case if I am standardizing a facility?
Shelf pack is 6 and the master carton holds 24, which is the quantity to reference when you are buying them for a whole site rather than one opening.
13) Is this padlock rated for commercial use or is it a consumer lock?
Commercial. The A3571 series is a commercial solid body padlock, with a dual stainless steel ball bearing locking mechanism that resists pulling and prying, which is what separates it from a hardware store laminated lock.
14) Do the A3570, A3571 and A3572 brass padlocks differ in shackle length?
They are the same 2 inch solid brass SFIC family and the number differentiates the shackle option within it. The A3571 carries a 2 inch shackle length with a 3/8 inch diameter. Order by the full model designation, since the keying suffix and the shackle are both carried in that number.
