The unique design allows the ramp's three sections to fold down to 16.625"" wide for compact storage when not in use. At the top of the ramp is a solid full width attaching lip providing heavy-duty support and grip to the loading surface. Each ramp is made of high quality aluminum so you won't have to worry about rusting or corroding. TF-6050 can hold up to 1,500 pounds of evenly distributed weight, yet only weighs 32 pounds The ramp includes a cam buckle safety strap to prevent ramp kick out when loading and unloading."
