"These over-sized aluminum Black Widow bi-fold ATV ramps are big enough to handle nearly any style of ATV up to 1,500 pounds. Each ramp features three heavy-duty hinges which allow the ramp to fold in half from 44"" down to 22"" for convenient storage and transportation. Rubber-coated fingers provide increased support and stability during loading and unloading, and prevent the ramps from scratching your trailer or tailgate. Raised serrated rungs on each ramp offer incredible traction in all weather conditions. The included adjustable safety straps prevent the ramps from kicking out while in use."
