To make sure you don’t choose the wrong product, take a look at the things you should consider before buying a door lock.

Construction of the Lock

The construction describes how durable your door lock will be. If you purchase all those locks that come with inexpensive builds, it might fall short in its durability and functionality.

That is why, even if you have to spend a bit more cash, you should go for stainless-steel door locks. These locks are powerful enough to withstand all the beatings. However, if you’re on a budget, I’ll suggest you go for the ones that are made from Zinc. Of course, you should make sure the door lock has Zinc die castings on it.


Rust Proof

There are plenty of junks you’ll find in the marketplace that does not have an anti-rust feature. You might be able to get these door locks in exchange for a little amount of money, but soon your money will go to waste. Because within 2 to 3 months, they’ll start getting rust and corrosion.

Locking Mechanism

What good is a door lock if it doesn’t have a good locking mechanism? Unfortunately, there are tons of door locks that come with such low-end attributes. If your door lock doesn’t have a good locking mechanism, your lock won’t stay secure. One single pry and the next thing you know, the cargo door is wide open.

To make sure you don’t face such an unfortunate situation, get your hands on the door lock that has got strong ball bearings in it.If the ball bearings are strong, they’ll secure the lock to such an extent that it will be impossible for the thief to break your lock.
