How We Tested Those Padlocks ?

While normal padlock break easily, the cutter proof one’s are made with strong material and cannot be easily broken.

But how to choose? There are plenty of them.

Well that’s the point of this review and once i’m done, you’ll have more info about them and know exactly on what basis to make your purchasing decision.

In order to test and see the effectiveness of every padlocks, I used several methods, from bolt croppers, salt water tank, and hacksaws.

First of all, I placed our chosen padlock into a saltwater spray tank. For each hour, they were drenched for 10 seconds and then warm salty water was sprayed over them to see if they are susceptible to corrosion.

Then for a whole month, they were left in the tank which equates to more than one year of use. Once it was time to remove them, I tried to unlock them to see if the inside was still working. Once that was done, we could open it as a whole to check the inside.

Lastly, I used bolt croppers first to see how much time it would take to cut the shackles for each of them. If the latter didn’t work, I would then switch to the hacksaw.

Things You Consider When Buying Best Padlocks For Security

There are a few things to you’ll need to know before and when you are buying a padlocks.

The first one is, how valuable is the item you’re trying to secure. If they are just your common items or simple things, then a lower grade padlock should do the job with minimum investment but if you’re trying to secure important and valuable items, then it is better make a big long term investment to get a high security padlock.

Next is where will you be using it since for example, if you are using it for an outdoor garage is exposed to rain, then it is better to use a standard padlock that can be hardened with shackles. It will provide good security and easy to take off and put on for everyday use.

However there is rain often in your region and you are worried about corrosion, then it is better to get one of the best weatherproof padlock that will withstand the worst weather and different elements.

Lastly, you need to make sure that the type of padlock you are getting is suitable for the components and structure you are using it on. For example if you take one of the best high security padlock and use it with a hasp or flimsy chain, then it will be useless since the hasp or change will come out anyway under pressure.

And on a side note, if you need to use a lot of padlocks every day, it is better to try and master key most of them so that you don’t have to carry a dozen of keys around every day.
