"This apron-end aluminum walk ramp makes loading and unloading vans/trucks a breeze! Manufactured with lightweight aluminum making set up easy for one or two people, but strong enough to support 1,000 lb loads. A twin-tooth walking surface provides traction when traveling in either direction, and an angled apron provides a smooth transition from ramp to vehicle. Secure the ramp to your vehicle with the two included heavy-duty safety chains to prevent the ramp from kicking out. This 176 lb ramp is 39"" wide and 15' 9"" long."
