"These load leveler bridges are an essential tool for truckers transporting flat bed loads on a step deck trailer. Load levelers have an adjustable offset stake pocket post that can be rotated to different positions. This allows a .5 inch of adjustment of overall width to accommodate most drop deck trailers by simply pulling a pin and rotating. These load levelers will fit trailers with a 16"" drop including Doonan, Featherlite, and Transcraft stepdeck trailers. The stake pockets adjust from 97.25"" - 97.75"" wide (inside measurement of stake pockets across width of trailer). Load leveler bridges can be set up in minutes and are secured with chains and binders (not included). Welded brackets on bridges secure a 4x4 piece of wood (not inluded). Made from lightweight aluminum, these bridges are easy to handle. We also sell Load Leveler/Ramp combo kits if a modular loading ramp is needed."
