"Specifically designed for use with curbs up to 6"" tall, this heavy duty aluminum curb ramp is lightweight and easy to use. It can effortlessly be picked up and placed wherever it is needed. The innovative EZ-traction punch plate surface provides superior traction in wet, muddy, or snowy conditions, and also reduces mud and snow build-up on the ramp. The high strength military-grade aluminum provides a 600-lb weight capacity, and the 32"" width makes these ramps perfect for wide and heavy loads."
