The Heavy Duty Trailer Stabilizer is used to support and level the trailer while it is sitting or being loaded and unloaded at the loading dock. The HST-400 uses a 2 speed gearbox for making fast contact with the trailer. With both an oversized top plate and base plate, the HST-400 is designed to securely hold the trailer in place. The Stabilizer Stand (ST-100) has an integrated carrying handle, and the adjuster pulls have vinyl grips, making transporting and adjusting the ST-100 to the trailer fast and easy. All Butler loading dock safety equipment is finished in bright yellow for quick identification by drivers and dock workers.
