The female side ramp makes up one section of the AMS or Advanced Module System. The female cord ramps are designed with slots that attach to the male counterparts on the long edge of its center section. A smooth transition is created when the ramp is attached to the center cover. Raised diamond treads help pedestrians and vehicles gain traction during the snow or rain. The short ends contain "Dog-Bone" connectors that are used for attaching extra side ramps and center covers to expand a usable area. These female ramps are compatible with the 3-channel AMS hose covers. All units are proudly made in the USA.
