How It Works
A TrestleJack has no moving parts. It is a 2-in-1 device that doubles as an automatic trestle with axle lifting capability.
It uses the driving motion from the vehicle for lifting and lowering trailer axles without any human effort. Once in the upright position TrestleJacks becomes a safe axle support stand that does not require additional axle support.
It is quick and easy to use. Simple as 1-2-3
