The lightweight, polyurethane ramps are a part of the five-channel AMS (Advanced Modular System) ramp system. The female ramps feature slots that are interlocked with the prongs of an AMS center cable cover. Once the full AMS system is put together, a smooth transition is created over the protected cables. A pattern of raised diamond treads maximizes traction during cold, wet weather. Dog Bone connectors are located on each side of the female ramp to continue a seamless and unlimited number of AMS sections. These female ramps, and male ramps only work with the five-channel AMS protectors with the Yellow Jacket label. The Yellow Jacket cable ramps are proudly made in the USA.
