Stabilizing Spin Top Beam Jack

The trailer stabilizing jack is used to prevent upending semi-trailers when they are not connected to a tractor during loading and unloading operations. It is also used to level trailers parked on sloped ground and to prevent landing gear from sinking into a soft surface. It's made of high strength steel construction with a flush-type zerk fitting for lubricating ACME screw. Meets OSHA regulations when used with wheel chocks. Contains a powder-coat safety yellow finish that includes a reflective collar for visibility at night.
