Why a Garage Door Lock Bar

You have several options when it comes to securing your garage. Some of the most common options for garage security include using chains or cables, but those can typically be cut with a few tools, making them not the most robust option.

Garage door lock bars are the safer option as they use sturdy bars or rods to secure your garage. They often come in kits, making them easy to assemble and install.

This security option is also versatile and easy to make work for your garage. If you find that one lock bar isn’t long enough for your garage, you have the option of overlapping two of them and bolting them together.

Other garage security options include deadlocks and latches. No matter what type of security you choose, make sure that you take into account the type of garage door you have and its configurations as you choose the best lock bar for you.

Let’s take a look at your options when it comes to lock bars and other garage door security.
