Easily access a transport truck trailer deck with a step deck ladder! Attaches to truck trailer rub rails using two specially designed pin clamps, no tools required. Includes (2) C-Brackets which hold the ladder firmly in place when stored on the deck in an upright position. Drop deck ladder configuration allows it to be locked to the trailer deck using a padlock (not included). Also works great for flat bed trailers! The transport truck ladder is made with lightweight aluminum designed to support up to 375 lbs while remaining light enough to be carried around between uses.
