Check the materials of a lock before you check the design. Different materials have different levels of protection. Trailer locks are made of aluminum, steel, zinc, copper alloys and others.

Furthermore, you can customize the safety of your trailer as well. In fact, these trailer locks can even provide the maximum security.
You can not just do without checking the compatibility of the lock before buying. Not all the hitch locks support all the trailer couplers. Don’t forget to measure the trailer hitch before you considering buying a lock. It’s helpful to determine the precise coupler lock for your trailer.

The good news for you is, the manufacturers are now producing locks that are universally compatible. They also recommend the range of couplers compatibility.
