Buyers Guide to Select a Best High Security Padlock

If you don’t have any idea and are in dark about the high security padlock available in the market then this buyers guide you should must read before making your selection go the best high security padlock for your home or anything that needs to be protected.

So Basically there are four types of padlock available in the market that are Long shackle, open shackle, closed shackle and straight shackle.

Shackle is U- shaped part that you see in a padlock. It’s is this shackle which need most consideration while selecting a padlock.

Long shackle padlock can be used for number of fitting but are very easy to breach. The longer the shackle it’s easier to break it.

Open shackle padlock are the most commonly used padlock from low to high security usage but again they are easy to break in.

Closed shackle padlock are hard to break due to small opening in the shackle which makes it purpose limited to few things.

Straight shackle are one of the most complicated of all and you can find there usage at gates, shutters, doors etc. and are best for security purposes.

Now you know which padlock to go for so its become rather important to look some of the few quality of a padlock which are mentioned below.

Features to look For

When you go out for a shopping of a high security padlock some of the features must be kept in mind. A uncuttable padlock must have some level of complexity so that it can delay the thief from braking in.

Below we have addressed some of the features of a good master lock.

Shackle Material

The shackle part of a padlock is exposed outside so its the main component or we say is the heart of the padlock so the material must be genuine to prevent the padlock from breaking. Usually shackle material types can include brass, stainless steel, hardened steel, hardened boron steel alloy, boron carbide, and molybdenum steel alloy.

Brass and stainless steel are the lower grade and offer minimum security.

hardened steel and boron steel are the midrange steel type whereas the most complicated and strong are the boron and molybdenum steel locks.

Number of Pin in Key

As a rule of thumb the more the number of pins the more secure will be the padlock.

Usually the padlock ranges from 3 pins which are the least secure to 7 pins which are most complicated one but manufacture mostly produce 5 pin padlock with mid range security.

So choosing the padlock with 7 pin can enhance your security.

Removal Core

Some padlock comes with a removal core in this case if your lock is damaged or some one has a duplicate key of your padlock you do not need to buy a new padlock all again you just pull out the padlock core and replace with the new one.

Lock Size

Bigger the size of the lock more secure the lock will be as it provides more space for pins and also the diameter would be large which will make difficult to break but remember this lock can be used for limited purpose due to its heavy size and large diameter.

Final Takeaway

Always keep in mind what is the purpose of your padlock, high security padlock must be used outdoor and most important it should be corrosion resistant as a rusted padlock will never provide the same level of security as the new security padlock.

Price is major consideration, one can not buy the best security padlock at low price. Padlock that cost few bucks are the easiest to breach so always try to buy the branded padlock even if it cost few bucks more than the normal one but it will protect anything of significant value.

Finally always remember security of your essentials extend beyond the padlock even the most robust, sophisticated and highest security padlock can not protect your essentials unless the thing the padlock is put on is strong enough, make sure your doors, your shutter, gates etc. should also be made of highest grade quality, alone padlock can not sufficient to protect your belongings.
