The Original California Immobilizer Trailer Wheel Boots – Generator Trailer Locks


California Immobilizer trailer wheel boots are commercial grade trailer boots designed for the ultimate in portable trailer security or as a long term trailer storage security solution.

Our California immobilizer generator trailer locks are a light weight, extremely tough commercial wheel boot solution. Our generator trailer wheel boots can be keyed alike for a fleet of trailers by us prior to shipment. They are built tough, out of high strength steel and bright yellow powder coated for visibility and durability. California Immobilizer generator trailer locks are easy to install on all trailers – horse trailers, generator or welding trailers, recreational trailers – and are extremely simple to remove by key holders – almost impossible to remove by anyone else!

Installing The Immobilizer Generator Trailer Locks

The process for installing one of our these generator trailer locks is very simple. Because it is a trailer boot design, just follow the curve on the fender then rest the lug plate on the ground. Connect the locking bar and push the lock into place. Removal takes only seconds.

Unlike other models on the market, our trailer wheel boots completely cover the lug nuts eliminating the possibility of tire removal. The frame acts as a chock that prevents the vehicle from moving even slightly forwards or backwards making even towing extremely difficult if not impossible. Our California Immobilizer trailer wheel boots are easy to carry for ease of transport and feature multiple steel attachment points to the wheel which would require numerous cuts through heavy gauge steel if an attempt were made to physically cut the wheel boot off.

The California Immobilizer is our original and best selling model of our trailer locks and boots, featuring all steel construction designed to secure any wheel against any unauthorized use.

We offer handy storage solutions (see below) for storing your trailer wheel boot on the side of your trailer when not in use.

Recommended Uses – The California Immobilizer can be used to secure cars, trailers, generators, cargo/horse trailers, light sets and compressors. We can even customize The Immobilizer to fit your needs, providing custom car boots for unique applications.

The Immobilizer trailer wheel locks in the boot design fit a wide range of generator trailers, boat trailers and trailer mounted rental equipment.
