American Lock AME-A1266MK BLK 2KEY – Frequently Asked Questions

1) What does the MK in American Lock A1266MK mean, and how is it different from the A1266KA or plain A1266?
MK means master keyed: each A1266MK padlock comes keyed different from the others, but all of them open under a common master key you specify. The plain A1266 (A1266KD) is keyed different with no master, the A1266KA is keyed alike so one change key opens every lock in the group, and the A1266KAMK is keyed alike plus master keyed. If you want maintenance to carry one key while each tenant or department keeps its own, MK is the one to order.
2) Will the A1266MK padlock shackle fit through my hasp? What are the shackle dimensions?
The shackle on the A1266MK is 5/16 inch in diameter, 2 inches tall, with a 3/4 inch clearance between the legs. So your hasp staple has to accept a 5/16 inch bar, and the material you are locking through cannot be thicker than the 3/4 inch horizontal opening. The lock body itself is 1-3/4 inches wide.
3) Can the A1266MK be rekeyed later if a key goes missing?
Yes. It uses a rekeyable 6-pin APTC14 cylinder, so a locksmith can repin it into a new master system rather than scrapping the lock. American Lock lists tens of thousands of key changes on that cylinder, which is what makes it workable for large keyed properties.
4) What padlock matches the American Lock A1266MK's 5/16 inch shackle diameter if the facility is standardized on a brass-body lock?
The Schlage KS23D/KS23F brass padlock also uses a 5/16 inch diameter shackle, so it drops into the same hasp openings as the A1266MK, which carries a 5/16 inch shackle diameter with a 2 inch shackle length. The difference is body material and keying approach: the A1266MK has a solid aluminum body and a rekeyable cylinder supplied keyed different under a master key, while the KS23D/KS23F is a brass-bodied lock in Schlage's 20 Series.
5) What is the equivalent to the American Lock A1266MK for lockout/tagout on electrical gear, where an aluminum body is a concern?
For energized electrical work, look at the ABUS 74/40 insulated safety padlock, which has a 6-pin cylinder, a 1/4 inch shackle diameter and a 1-1/2 inch body width, or the ABUS 76/40, a plastic-covered aluminum core padlock with a 1/4 inch shackle diameter. The A1266MK is a solid aluminum body 1-3/4 inch wide with a 5/16 inch boron alloy steel shackle - heavier duty for gates, tool cribs and storage, but the body and shackle are exposed metal.
6) Can I color code padlocks by crew or department with the American Lock A1266MK?
Yes. The A1266MK aluminum body comes anodized in black, blue, brown, clear, green, orange, purple, red and yellow, so you can assign a color per trade, building, or shift and still run them all under one master key. Same lock, same keyway options, just a different body color.
7) How many keys come with an American Lock A1266MK, and can I order it with none?
Standard supply is 2 keys per lock. You can also order 1, 3 or 4 keys per lock, or 0 keys per lock if your locksmith is pinning and cutting keys in house off your existing master system.
8) Is an aluminum body padlock strong enough for outdoor gates and yard use?
The A1266MK pairs a solid aluminum body with a hardened boron alloy steel shackle for cut resistance, and a dual ball bearing locking mechanism that resists pulling and prying. The black anodized finish is there for weather exposure. American Lock points this body style at self-storage units and lockers, tool cribs, manufacturing plants and harsh outdoor conditions.
9) Can I get the A1266MK with a chain so the lock stays attached to the gate?
Yes. It can be ordered with a #40 sash chain, 9 inches long, zinc plated, factory attached, or with no chain at all. The chain option keeps the padlock captive on the hasp or gate so it does not walk off when the opening is unlocked.
10) What is the difference between the American Lock A1265, A1266 and A1267?
They are the same 1-3/4 inch wide solid aluminum body with the same boron shackle; the number denotes shackle height. The A1266 carries a 2 inch shackle. If your hasp needs more or less clearance, the A1265 and A1267 are the shorter and longer shackle versions of the same lock, and each is available in KD, KA, MK, KAMK, uncombinated and zero-bitted.
11) What other brands of padlock should I look at instead of the American Lock A1266MK?
If you need a same-diameter shackle from another line, the Schlage KS23D/KS23F is a brass body padlock with a 5/16 inch shackle, and the Medeco 54515G is a 5/16 inch shackle indoor/outdoor padlock. For a facility running an interchangeable core program, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless shackle. For lockout/tagout rather than security, the lighter ABUS 72/30 aluminum safety padlock (1-1/4 inch body, 3/16 inch shackle) is the different animal, it is not a substitute for a boron shackle security lock.
12) Is the ABUS 72/30 aluminum padlock a substitute for the American Lock A1266MK?
They are not interchangeable on the same hasp. 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, a lighter lock typically used for departmental lockout. The A1266MK is 1-3/4 inch wide with a 5/16 inch shackle diameter and a 2 inch shackle length, so a hasp drilled for the American Lock shackle will not be secured by the thinner ABUS shackle, and a hasp sized for the 72/30 may not accept 5/16 inch.
13) Which padlock should be used instead of the American Lock A1266MK on coastal or wash-down exterior openings?
For salt-air and constantly wet locations, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less pop-out cylinder, and the ABUS T84MB/30 Nautic is a sleeved marine-style lock with a 13/64 inch shackle diameter and 1-17/64 inch body width. The A1266MK uses a solid aluminum body with a boron alloy steel shackle, which is built for harsh outdoor and manufacturing environments but is not a stainless or sealed body.
14) What padlock offers a thicker shackle than the American Lock A1266MK for a high-risk gate?
The Medeco 5260 in the 52 Series has a brass body and a 7/16 inch shackle diameter with M3 key technology in a satin chrome finish, a heavier shackle than the 5/16 inch boron alloy steel shackle on the A1266MK. Confirm the hasp or chain link will pass 7/16 inch before switching, since a hasp sized for the A1266MK may only clear 5/16 inch.
15) We want audit trail and scheduled access instead of a mechanical master key - what replaces the American Lock A1266MK?
The Medeco 54515G XT is an electronic indoor/outdoor padlock, non-key retaining, with a 5/16 inch shackle diameter and cylinder included, so it matches the A1266MK's 5/16 inch shackle diameter at the hasp while moving access control to an electronic credential. The A1266MK stays mechanical: a rekeyable 6-pin APTC14 cylinder supplied keyed different under a master key, with 2 keys per lock as the standard pack and other key counts available.
16) How many American Lock A1266MK padlocks come in a case?
Shelf pack is 6 locks and the master carton holds 24. Useful if you are standardizing a facility and want to order full packs rather than singles.
17) Is the A1266MK padlock meant for commercial use or residential?
It is catalogued by American Lock as a commercial solid body padlock, and the stated uses are self-storage, lockers, tool cribs and manufacturing environments. It will work fine on a shed or gate at home, but the build and the master keying options are aimed at multi-lock facility programs.
18) Does the American Lock A1266MK retain the key when unlocked, and what are the alternatives either way?
On the key-retaining question, the Sargent 758 is a key retaining standard padlock in a US4 satin brass finish, while the Sargent 858 is the non-key-retaining version with a stainless steel shackle in the same US4 satin brass. Those are the two options to specify against if your procedure requires the key to stay captive in the lock while open; the A1266MK is chosen instead for its solid aluminum body, 2 inch boron shackle and rekeyable cylinder supplied keyed different under a master key.
