American Lock AME-A3107WOMK BLK 2KEY – Frequently Asked Questions

1) Does the American Lock A3107WOMK padlock come with a cylinder, or do I have to supply my own core?
No core in the box. The A3107WOMK ships without a cylinder, so you supply your own small format interchangeable core to match the keying system already running in your building. That is the point of the WO models: a facility that already stocks SFIC cores drops its own core in and the padlock joins the existing key system on day one. If you would rather buy the padlock with the core already fitted, American Lock's A3105CY family is the cylinder-included version of the same aluminum SFIC line.
2) What does the MK suffix mean on the American Lock A3107WOMK, and how is it different from KA or KD?
MK means keyed different under a master key: every padlock in the order has its own change key, and one master key opens them all. That is the setup a property manager or maintenance supervisor wants when each tenant, cage, or crew gets their own key but the facility keeps one key that opens everything. The rest of the family covers the other patterns. A3107WOKA is keyed alike, so one key runs every lock. A3107WO (A3107WOKD) is keyed different with no master. A3107WOKAMK is keyed alike under a master. A3107WOUN comes uncombinated for a locksmith to pin on site.
3) Will a 3 inch shackle on the American Lock A3107WOMK reach through a hasp on a gate chain or a job box?
The shackle is 3 inches tall, 1/4 inch in diameter, with 3/4 inch clearance between the legs. That 3/4 inch is the number that decides it: whatever you are locking through, staple, hasp loop, chain link, or lockout tab, has to pass into a 3/4 inch gap, and the total height available for stacking material is 3 inches. Boron alloy steel is the shackle material, chosen for cut resistance rather than reach. On a thick shrouded hasp where 3/4 inch of clearance is not enough, this one will not close.
4) Will my existing SFIC cores from my building master key system fit the American Lock A3107WOMK padlock?
The A3107WOMK takes a small format interchangeable core, and 16 interchangeable core keyways are offered so the padlock can be brought onto the key system already running your doors. Pull a core from your system, drop it in with the control key, and the padlock keys the same as the openings. That is what separates this from a standard padlock: you are not adding a second key to the ring.
5) I need a safety lockout padlock, is the American Lock A3107WOMK the right choice or should I use something else?
For lockout tagout, a keyed different or keyed alike lock without a master is usually what the program calls for, since a master key that opens a worker's lock defeats the purpose. The A3107WOMK is master keyed by design. It does carry the traits that make aluminum popular for the job, spark resistant, light, and available in nine body colors for crew assignment. If the program forbids a master, the same padlock is made as the A3107WOKD keyed different or A3107WOKA keyed alike. Purpose built safety padlocks from other brands include the ABUS 72/30 anodized aluminum safety padlock with a 1-1/4 inch body and 3/16 inch shackle, and the ABUS 74/40 insulated safety padlock with a 1-1/2 inch body and 1/4 inch shackle.
6) I need an aluminum body padlock that ships with its own cylinder, not one that takes a core. What should I order instead of the A3107WOMK?
The A3107WOMK ships without a cylinder because it is built to accept a small format interchangeable core. If you do not run a core system and want a lock that arrives complete, the ABUS 74/40 is an insulated safety padlock with a 6-pin cylinder, a 1/4 inch shackle diameter and a 1-1/2 inch body width - the same shackle diameter and body width as the A3107WOMK. The ABUS 76/40 is a plastic-covered aluminum core padlock, also with a 1/4 inch shackle diameter, at 1-37/64 inch width.
7) The hasp openings on our lockers are tight and a 1-1/2 inch aluminum padlock will not seat. What is a smaller aluminum lock?
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, both smaller than the A3107WOMK at 1-1/2 inch body width and 1/4 inch shackle diameter. The ABUS T84MB/30 is smaller again at a 1-17/64 inch body width with a 13/64 inch shackle diameter. Measure the hasp slot against the shackle diameter first, then the staple opening against the body width.
8) Will the A3107WOMK aluminum padlock hold up outdoors on gates and utility enclosures?
Solid aluminum body, black anodized, and corrosion resistant, which is why this body style gets used on utility equipment, self storage, and tool cribs. Aluminum is also spark resistant and light, so it suits fuel, chemical, and confined space work where a steel body is a problem. It is a commercial grade lock, not a residential one. If your application is submerged or constantly salt washed, a stainless body such as the Medeco 521 G8R weather tight padlock is the different construction to look at.
9) Can I color code American Lock A3107WOMK padlocks by trade or by department?
Nine body colors are made: black, blue, brown, clear, green, orange, purple, red, and yellow. Crews use that to separate departments, buildings, or lockout assignments at a glance without pulling a tag. The color is in the anodized finish of the aluminum body, so it does not wear off like paint or a sticker. Each color is a distinct catalog number, for example A3107WOMKBLU for blue and A3107WOMKRED for red, so order the color as part of the part number.
10) How many keys come with an American Lock A3107WOMK, and can I order extras or none at all?
Standard is 2 keys per lock. You can also specify 1, 3, or 4 keys per lock, or 0 keys per lock. The zero key option is what a locksmith or a facility with its own keying operation orders, since the padlock takes your own SFIC core anyway and you cut keys off your own system. Decide this on the order form, it is a specified option and not something that can be changed after the cores are pinned.
11) Can I get an American Lock A3107WOMK padlock with a chain so it stays attached to the gate?
Yes, a #40 sash chain option is offered, 9 inches (229mm) long and zinc plated, factory fitted to the padlock. That keeps the lock tethered to the hasp or gate frame so it does not walk off or land in the mud when the gate is open. If you do not want it, the chain option is ordered as NONE. Specify it when you order, it is not a field accessory you add later.
12) What is the difference between the American Lock A3105, A3106, and A3107 aluminum SFIC padlocks?
They are the same solid aluminum small format interchangeable core padlock body in different shackle lengths, and the A3107 is the long shackle of the three. The A3107WOMK carries a 3 inch shackle at 1/4 inch diameter with 3/4 inch clearance on a 1-1/2 inch wide body. Pick the A3107 when you need to reach through a chain, a thick hasp stack, or a gate loop; step down to the A3105 or A3106 where a shorter shackle gives less room for a bolt cutter to get a bite.
13) What else could I buy instead of an American Lock A3107WOMK if I need a removable core padlock on a Sargent key system?
Sargent makes its own removable core padlock, the 60-858-2, with a 2 inch stainless steel shackle, and it is the one to look at if your building runs Sargent keying and you want the padlock native to that system rather than an SFIC core dropped into an aluminum body. The trade off is body material and reach: the A3107WOMK is aluminum with a 3 inch shackle, the Sargent is a stainless shackle at 2 inches. For a plain brass body padlock without the interchangeable core, Sargent's 758 is key retaining and the 858 is non key retaining, both with stainless shackles in US4 satin brass.
14) Which padlocks look like a substitute for the A3107WOMK but will not take a small format interchangeable core?
Several padlocks in the same size class are built around a fixed or proprietary cylinder rather than a core pocket. The Medeco 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter using M3 key technology. 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. The Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle. Each is keyed into its own system, so none of them will drop into a small format interchangeable core master key system the way the A3107WOMK does.
15) We lock outdoor utility cabinets on the coast. Is an aluminum padlock the right call or should I use stainless?
The A3107WOMK uses a solid aluminum body, which is corrosion resistant, spark resistant and lightweight for harsh environments. If you want a stainless steel body instead, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body supplied less pop-out cylinder, so it also arrives without a cylinder for you to key into your own system. Choose the aluminum A3107WOMK where weight and spark resistance matter and the stainless 521 G8R where the body itself is taking direct weather.
16) Do I need a key retaining padlock for our tool crib, and which options are which?
The A3107WOMK is a keyed padlock supplied without a cylinder, so its retaining behavior follows the core you install. Among comparable padlocks, the Sargent 758 is key retaining with a US4 satin brass finish, meaning the key cannot be removed while the lock is open. The Sargent 858 is non-key retaining with a stainless steel shackle in US4 satin brass, and the Medeco 54515G XT electronic indoor/outdoor padlock is also non-key retaining with a 5/16 inch shackle diameter. For a tool crib where locks get left hanging open, key retaining keeps the key with the lock; non-key retaining lets the holder walk away with the key.
17) We want to color code padlocks by crew or by building. Which padlock supports that and what is the alternative?
The A3107WOMK solid aluminum body is offered in black, blue, brown, clear, green, orange, purple, red and yellow, which lets you assign a color per crew, per building or per lockout owner while every lock still takes the same small format interchangeable core. Among comparable locks, the ABUS T84MB/30 Nautic uses a black sleeve, and the Sargent 758 and 858 are finished in US4 satin brass, so those identify by finish rather than by a color range. If color coding across a fleet is the requirement, the A3107WOMK is the one that carries it.
18) Is there an electronic padlock alternative if we want an audit trail instead of a mechanical core?
The Medeco 54515G is an XT electronic indoor/outdoor padlock with a 5/16 inch shackle diameter, non-key retaining, and it ships with a cylinder. That is a different security model from the A3107WOMK, which is a mechanical padlock supplied without a cylinder so you can install a small format interchangeable core keyed into an existing master key system. Go electronic where you need credential-level control at the lock; stay with the A3107WOMK where the site is already standardized on interchangeable cores and a physical master key.
19) Our self-storage doors need a longer shackle reach than a short-shackle padlock gives. What compares?
The A3107WOMK carries a 3 inch tall shackle at 1/4 inch diameter with a 3/4 inch shackle width, which suits self-storage units, lockers and tool cribs. If your comparison is against a shorter reach, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle and the Sargent 82-856 uses a 2 inch by 2 inch brass case. Check the clearance you need through the hasp before you settle on shackle length, since a longer shackle gives reach but also gives more of the shackle to a cutting tool.
20) How many padlocks are in a case of American Lock A3107WOMK, and is there a smaller pack for a single site?
Master carton is 24 padlocks, and the shelf pack is 6. A large property or a utility standardizing across yards typically orders by the carton of 24; a single building or one crew's worth is closer to a shelf pack of 6. Since colors and key counts are ordered as separate part numbers, split your quantity by color before you build the order.
21) Is the A3107WOMK padlock body wide enough to cover a standard hasp, and how much space does it need?
Body width is 1-1/2 inches on the solid aluminum lock, which is the common commercial padlock body size and sits within the pocket of most standard hasps and lock boxes. Where clearance gets tight is the 3/4 inch shackle gap and the 3 inch shackle height, not the body. A shrouded hasp built for a wider body will accept it, but the shackle will sit exposed rather than protected, so match the hasp shroud to the 1/4 inch shackle diameter if shrouding is the reason you are buying.
22) How does the American Lock A3107WOMK resist someone prying or pulling the shackle out?
A dual ball bearing mechanism holds the shackle at both legs, which is what resists a pull or a pry attack compared to a single locking pawl. The shackle itself is boron alloy steel at 1/4 inch diameter for cut resistance. Together those are the two attack paths a padlock on a gate or storage unit actually sees: cutting the shackle, and levering the body off it.
23) For lockout tagout on electrical gear, which padlock body material should I pick?
The A3107WOMK uses a solid aluminum body that is spark resistant and lightweight, and it comes in nine lockbody colors for assigning locks to individual workers. Comparable safety padlocks include the ABUS 72/30 anodized aluminum safety padlock at 1-1/4 inch body width and the ABUS 74/40 insulated safety padlock at 1-1/2 inch body width with a 1/4 inch shackle. Where the lock must be keyed into a facility-wide master key system, the A3107WOMK accepts a small format interchangeable core; the ABUS 74/40 comes with its own 6-pin cylinder instead.
