How Does a Portable Door Lock Work?

Spending a night at a hotel or a rental place can turn into a bad experience if the doors are not secure enough. You won’t be able to sleep freely in an unprotected room. But, you can change everything with a simple security device. A portable door lock is an excellent choice for the above situation. If you are a constant traveler, carrying a portable travel door lock is a must-have. So, with my personal experience, today, I’m hoping to share some knowledge on how a portable door lock works.

A portable door lock comes with a steel plate that goes into the door strike. First, insert the steel plate into the door strike. Then place the red wedge on the steel plate. Finally, adjust the metal tension rod to lock the door.

Portable Door Lock’s Mechanisms

Portable door locks come in several different shapes and sizes. But, overall, they all have similar mechanisms and uses. For instance, preventing the door from opening inward is the primary purpose of a portable door lock. Whatever the type or the design, a portable lock should do that.

Parts of the Portable Door Lock

A portable lock is a device that comes in a combined unit. But there are two main parts of the lock.

All portable locks have a part similar to a red wedge. This red wedge is the lock, and it has an adjustable metal tension rod. The red wedge and the steel plate connect via the chain.

Keep in mind: When someone applies a horizontal force to the door, that force is converted into a vertical force and tightens the lock even more. So, it is nearly impossible to open the door from the outside. (2)
