Master Lock 421 Lockout Tagout Hasp with Vinyl-Coated Handle and Extended Jaw, Red

These have one purpose and as they have one purpose they have only do one thing and that is to lock out potential electrical energy from being released by the system being locked out. This they do very well and they are durable. The key with this product is it only works if all parties work together and do their part. The device itself is worthy and it does its part. You can count on it to do what it was designed. Getting all who use it to do their part is another issue altogether.

The product kind of looks cheap, but it really is quite sturdy. We use it in our escape room plans with multiple locks. I really like it!

I have to confess I don't use this hasp for its intended purpose. I use mine to secure a military canvas duffle bag with TSA approved locks. It's perfect in that role since there are apparently no larger size TSA approved locks out there. This hasp is quite sturdy and on a heavy side. It is also somewhat larger than I anticipated. In a retrospect I should have gotten a 1" one. I am more than sure it is great for what it was designed, lockout of unwanted use.

Good product

If you have a case that has smaller hasp openings than your locks, these are cheap and will help you use your larger locks!Case in point: I ordered some Pelican P1075 cases to use for securing my firearm in the car. They're nice cases, but the lock loops/hasp openings on the edges were too small for even a fairly narrow 1/4" lock hasp! I was a bit upset and didn't want to file/drill out the plastic (it was thin enough as it is). So after some Googling and Amazon'ing I found these! I wasn't exactly sure they'd fit, but I was very happy that they did! When closed (and they close securely like overlapping teeth), they two red parts line up leaving an array of 9/32" holes - perfect for 1/4" lock hasps - even multiple locks!Using these, my locks and a sturdy chain, I can keep my handgun safely in the car when I can't carry into the building/site. Yes, a determined thief could still make off with the entire case, or just cut open all the reinforced plastic, but still, it's a deterrent.

I got this to do Breakouts in my classroom and it works great. Very sturdy and I love that I can put multiple locks on it to make the challenge more difficult.

I am a teacher and used these for a breakout activity. These worked great! Very happy. My students had never seen them before and were amazed. Might use them for other things, not sure. They are sturdy but I do not know whether they are easily cut through; again, I only used them for a breakout activity at school.

Does the job
