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

Well made.

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.

There isnt much to these. Easy to see and mechanism is easy to turn. Dropped it on concrete a few times and its fine.

Master Locks odd hybrid tagout / lockout creation baffles. Here is the lock core Master Lock *ought* to be using with their tough hardware, inserted into a plastic shell, for a non-high security purpose. TOLO locks don't NEED to be high security - just need to be enough to prevent operation of dangerous equipment by careless people - basically they need to be lockable tamper seals. A perfect place to use their marshmallow soft four pin cores, yo go along with plastic bodies. Instead, the TOLO lock has the flimsy body, and the tough six pin core. Isn't that exactly backwards? Master Lock is notorious for easy cores in tough hardware, but they have this tough core available - why don't they swap..?! Four stars because this IS a good core, and will certainly lockout equipment, over-kill style. My lock-picking skills are in for a test!

A good sturdy lock that fits on lock out breakers.

can't comment on their utility as actually LOTO lock applications besides that dollar 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.

Good product would buy again

I bought this lock because I felt like spending a bit more to go with a quality name brand that can withstand the rigors of being in an industrial environment. I was a bit disappointed when a cheap lock with a fully plastic body arrived, and even more disappointed with the operation. You need to have it in just the right position for the lock to come undone, and pulling the key out is an exercise in your jiggling ability. I'm hoping the key will loosen up with time and break in a bit, but this purchase has left me with regret.
