"The beveled threshold ramp from EZ-Access is great for providing a smooth, gradual transition from the ground to a doorway threshold. These threshold ramps feature beveled sides. The ramp has a 850 lb. weight capacity and works even better on sliding glass doors because it does not interfere with the door track! The beveled ramp can be used indoors or outdoors and is made entirely of 100% recycled rubber! The ramp has a 4-1/5"" rise and is 25"" long. The rubber construction provides traction when using the ramp. Included with your purchase of a beveled threshold ramp is a lifetime manufacturer's warranty and free shipping!"
