Master LockRed Lockout Tagout Safety Padlock with Key, Metal Shackle and Non-Conductive Lock Body for Electrical Applications, 410RED

A good sturdy lock that fits on lock out breakers.

can't comment on their utility as actually LOTO lock applications besides thatdollar for dollar, you can't find a better core for the price as these.i've bought a few and none were "easy" opens. occasionally stats align and build tolerances work it out such that within the same exact production runs of locks you'll occasionally get one that's oddly simple to open, and another that makes you questions what happened to the skill set you believed you could make pretty straightforward work out of this plastic lock that won't open for you seemingly for anything you are throwing it's way.I'd reccommend buying a few, make sure they're keyed differently (usually are given the LOTO application) that way you really are sure to make these the best training tools you can find for under $20.Say word son.

For those of us in the Locksport Community, we all know Master Lock is the butt of a great number of jokes because their products are truly horrible. However, this padlock is a rare exception. This lock is NOT designed to withstand physical attacks; the body is made of plastic. However, with a 6-pin core containing all security pin drivers, it's great practice for those looking to sharpen or maintain their skills with spool and serrated pins. My attached pictures give you a look inside the lock. The lock housing is not designed to be opened; the plastic body is sealed. I broke mine open along the seam line and then super-glued it back together. The plug has a standard Master Lock keyway but because the entire core is relatively small, maneuvering your pick can be a little tricky due to limited space. Also, this is a dead core meaning there is no spring tension on the plug. Precision tension therefore becomes very important which is more great practice. My lock (and I assume yours will too) contained 5 spool drivers, 1 serrated driver (having two spaced out serrations), and 6 standard key pins. For prices in the single digits, you just can't beat this lock. Now, if someone could only talk Master Lock into pinning ALL their locks this way...[***WARNING*** ] The opening in the plastic body through which the key is inserted is warded so that when turning the key to unlock it, the key (and therefore the plug) will only rotate 90 degrees before stopping. After successfully picking this lock, DO NOT rotate the plug anywhere near 180 degrees. Stop at 90 like the key does. The reason for this is because if you rotate the core 180 degrees, all of the key pins in the plug will fall out inside the body of the lock. You will then be forced to either throw it away or crack it open and re-pin it. You can see in one of my pictures what the lock will look like once you crack it open if you pick it and rotate the plug too far. All of the key pins are laying loose in a recess.

esteticamente es bonito, agradable al tacto, hubiera sido mejor que viniera con al menos 2 llaves, tiene buena calidad, pero estoy seguro que con unos buenos golpes lo abren fácil, así que no es muy seguro.

It's a lock out tag out once you put it on and lock it... it's locked. Really nice quality

Best lock core I've seen in a Masterlock. All 6 pins are security pins. The ones I received have 5 spools and 1 serrated pin. I'm not sure if the numbers of each vary from lock to lock, but since both of mine have the same, I'd bet they all are. Both have pretty extreme bitting making them a challenge.Do not rotate core past 90 degrees!! The key pins will all dump out into the lock body. Even knowing this beforehand I still managed to do it with one of the locks and had to split the body open and re-pin it. It's really easy to over rotate if not paying attention.Overall, they are great locks to hone or develop your skills with security pins as they are cheap and have a challenging core. However, they would be less than useless to secure valuables as they are designed for lockout tagout and one strike from a hammer would shatter lock body and shackle would fall open.

Excelente calidadPara un trabajo donde se requiereEsta perfecto

I bought this lock because it was a recommended great training piece from guys in the lock sport community, which I’m new to. I’ve mastered all the store available locks but this one’s frickin tricky! I’ve had it over a month and still haven’t had success picking it. Try it out!
