American Lock AME-A22MK 2KEY – Frequently Asked Questions
1) Will the American Lock A22MK fit my hasp? What are the shackle clearance dimensions?
The A22MK gives you 3/4 inch of shackle width (the horizontal clearance between the shackle legs) and a 3 inch shackle, with a 5/16 inch diameter shackle rod. So your hasp staple has to accept a 5/16 inch rod and sit within that 3/4 inch opening. The body itself is 1-3/4 inches wide, which is what has to clear any recess or shroud on the hasp.
2) What does the MK in American Lock A22MK mean for keying?
MK is the master keyed version: each padlock is keyed different from the next, and a master key operates the whole group. That is the setup a property manager or facilities crew wants when each tenant, locker, or gate gets its own key but maintenance carries one key that opens them all. If you want every lock to open on the same change key instead, the keyed alike A22KA is the one to order, and A22KAMK is keyed alike under a master.
3) How many keys come with the American Lock A22MK, and can I order it with no keys?
Key count is something you pick when ordering. The choices are 0, 1, 2, 3, or 4 keys per lock, with 2 per lock being the standard. Locksmiths and institutional buyers running their own key control usually take the 0-key option and cut keys off their own system; a maintenance crew handing out a spare normally wants 2 or 3.
4) What is the closest brass-body equivalent to the American Lock A22MK from another manufacturer?
The Schlage KS23D/KS23F is the nearest match in body material and shackle size. Like the A22MK, it is a brass padlock with a 5/16 inch diameter shackle. The A22MK carries a 1-3/4 inch wide brass body with a 3 inch shackle length and a 3/4 inch shackle width, so if your hasp clearance was set around those figures, confirm the Schlage will pass through the same opening before you swap.
5) I need a brass padlock with a heavier shackle than the A22MK - what should I look at?
The Medeco 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter, which is a thicker shackle than the 5/16 inch used on the American Lock A22MK. It is finished in satin chrome and uses M3 key technology, so it will not key into an American Lock system. Check that your hasp eye accepts the larger shackle diameter before ordering.
6) My facility standardizes on interchangeable cores - is the A22MK the right choice?
No. The American Lock A22MK uses a non-rekeyable 5-pin APTC12 cylinder, so it cannot take a facility core. If you run small format interchangeable cores, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, which lets you pin it into an existing SFIC system. The A22MK is the choice when you want a sealed cylinder and a 3 inch shackle rather than core interchange.
7) Can I use the American Lock A22MK for lockout/tagout on electrical equipment?
The A22MK is a commercial security padlock with a solid brass body and a hardened boron alloy shackle, intended for marine, self-storage, shed and workshop security rather than energy isolation. For lockout/tagout, the ABUS 72/30 is an anodized aluminum safety padlock with a 1-1/4 inch body and 3/16 inch shackle, and the ABUS 74/40 is an insulated safety padlock with a 6-pin cylinder, 1/4 inch shackle and 1-1/2 inch body. Those lighter, non-conductive bodies are the usual specification for electrical work.
8) Why choose a brass body padlock over steel or aluminum for outdoor and coastal use?
Brass is the reason to pick the A22MK. The 1-3/4 inch solid brass body resists corrosion in salty, caustic, and wet conditions, which is why it gets specified on marine and offshore work, docks, and exposed sheds and yards. The shackle is a separate story: it is hardened boron alloy steel for cut resistance rather than brass, so it is chosen for strength.
9) Can I get the A22MK padlock with a chain so it stays attached to the gate?
Yes. Along with the plain padlock, the A22MK can be ordered with a #40 sash chain, 9 inches long, zinc plated. That keeps the lock tethered to the hasp or gate so it does not get set down and lost, which is the usual reason it gets specified on self-storage, yard gates, and utility cabinets.
10) Is the A22MK hard to pick or pry open?
Two things do the work. The cylinder is a 5-pin APTC12 with serrated pins, which is what resists picking, and the shackle is held by a dual stainless steel ball bearing mechanism that resists pulling and prying rather than a single ball or latch. Combined with the 5/16 inch hardened boron alloy shackle, it is aimed at exposed applications where the lock is the only thing between you and the contents.
11) What is the difference between the American Lock A20, A21 and A22 brass padlocks?
They are the same brass solid-body family, and the difference between them is shackle height. The A22 carries the 3 inch shackle, which is what you want when the hasp is thick, the staple sits deep, or you are passing through a chain. If your hasp is tight and you want less exposed shackle to attack, step down to the A20 or A21 in the same series. All three are offered keyed different, keyed alike, and in master keyed versions.
12) What else could I use instead of the American Lock A22MK for a brass-body padlock?
Two close alternatives if you want brass on an outdoor opening: the Schlage KS23D/KS23F brass padlock uses the same 5/16 inch shackle diameter, and the Medeco 5260 from the 52 Series is a brass body with a heavier 7/16 inch shackle and M3 key technology. If corrosion is the whole problem, the Medeco 521 G8R is a weather-tight solid stainless steel body instead of brass. What none of those give you is the A22MK's 3 inch shackle height, so check your hasp clearance before swapping.
13) Does the key stay in the A22MK when it is unlocked, and what if I need key retaining?
The American Lock A22MK is a master keyed, keyed different padlock and the key is removable in the locked position, which is how a keyed different master keyed lock is normally carried. If your procedure requires the key to be trapped in the lock while the shackle is open so it cannot be walked off, the Sargent 758 is a key retaining padlock in a US4 satin brass finish. The Sargent 858 is the non-key retaining counterpart in the same satin brass.
14) For a coastal or offshore installation, is brass the right body or should I use stainless?
The American Lock A22MK uses a solid brass body specifically for corrosion resistance in caustic, corrosive and salty environments, and it is listed for marine and offshore security. If your specification calls for stainless instead, 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 uses a black sleeve over the body with a 13/64 inch shackle and 1-17/64 inch body width, which is a much lighter lock than the A22MK.
15) I want an audit trail of who opened the padlock - does the A22MK do that?
No. The American Lock A22MK is a mechanical padlock with a 5-pin APTC12 cylinder and a dual stainless steel ball bearing locking mechanism; there is no electronic record of use. For access records you would move to the Medeco 54515G XT electronic indoor/outdoor padlock, which is non-key retaining and uses a 5/16 inch shackle diameter, the same shackle diameter as the A22MK.
16) What is a good alternative if I need a larger brass case than the A22MK for a high-security opening?
The Sargent 82-856 is a non-key retaining padlock with a 2 inch by 2 inch brass case and a stainless steel shackle, built on the KESO platform. That is a larger footprint than the 1-3/4 inch wide body of the American Lock A22MK, and the KESO cylinder is a different key system entirely, so it will not integrate with an American Lock master key system.
17) How many A22MK padlocks come in a case if I am ordering for a whole facility?
Bulk quantities break down as 6 per shelf pack and 24 to a master carton. That is the figure to work from when you are standardizing a storage facility, a fleet of utility cabinets, or a campus on one master key system.
18) Is the A22MK a commercial-duty padlock or a homeowner lock?
It is classed as commercial. The pairing of a solid brass body, a hardened boron alloy shackle, and master keying is aimed at facility and MRO use, self-storage and locker banks, marine and offshore, and workshops and garages on a managed key system, not at a single homeowner padlock purchase.
19) Is a plastic-covered padlock a suitable substitute for the A22MK where I am worried about scratching a finished surface?
The ABUS 76/40 is a plastic-covered aluminum core padlock with a 1/4 inch shackle diameter and a 1-37/64 inch width, and the covering keeps the body off painted or finished surfaces. It is not a like-for-like swap for the American Lock A22MK, which carries a solid brass body, a 5/16 inch hardened boron alloy shackle and a dual ball bearing locking mechanism for pull and pry resistance. Use the ABUS where surface protection drives the choice and the A22MK where attack resistance does.
