Will it fit my trailer?

It makes no difference whether or not there are openings through your trailer wheel. Trailer Keeper will attach to your wheel with no problem.

It makes no difference whether or not there are brakes on your trailer. Trailer Keeper will attach to your wheel with no problem.

That is one of the many great features of the Trailer Keeper lock -- that it can be universally applied to virtually all trailer wheels 10 through 15 inches in diameter (To determine your wheel diameter, simply read the tire size designation stamped in the rubber on your trailer tire. A typical tire size is 205/75/R15. In this example, the wheel diameter is 15 inches. The last number in the tire size designation is always the wheel diameter.

Important note: A very small number of trailers are manufactured with cast aluminum or cast magnesium wheels, commonly known as “mag” wheels. Trailer Keeper was not designed for application on trailers with “mag” wheels and, therefore, will not properly attach to “mag” wheels.

There is a minor modification which you can perform to allow Trailer Keeper to attach to "mag" wheels. Call us toll free at 1-800-709-3343 and we will gladly describe the minor modification to you.
