GUARDIAN™ Fixed Height Trailer Stabilizers

in Trailer Stabilization


Two fixed height Guardian jacks can take the place of heavy, clumsy ratchet jacks for supporting the front end of a parked semi-trailer.

Most parked trailers stand 46" above the pavement, so it's easy to slip the 45" tall Guardian jacks under the nose. Then all you do is give the trailer landing leg's handle a few cranks to lower the trailer to contact the jack.

To remove the jacks, crank the landing leg handle a few times to lift the nose just enough to slip the two jacks out from under.

What could be simpler? SEE OUR VIDEO and you will see how easy it is to use Fixed Height Guardian jacks.

Use landing leg handle to lower or raise trailer nose!
