The polyurethane ramp sections are lightweight and easy to install to their AMS (Advance Modular System) cable cover system. The male ramps contain prongs that drop into one side of the AMS center sections to create a smooth transition over the protected cables. The upper side of the ramp section features raised diamond treads that maximize traction during wet and icy conditions. Each short end contains a Dog Bone connector - a male and female connection - that extends with additional AMS cable ramps and center covers. These male and female counterpart ramps are only compatible with the five-channel AMS cable covers. All Yellow Jacket products are proudly made in the USA.
