Dynamic Perception 20" Stage One Carbon Fiber Rails Extension, Set of 2

The Dynamic Perception 20" Stage One Carbon Fiber Rails Extension (Set of 2) are the core of the Stage One system. Unlike the standard extension sets, the Fixed-Span extension set comes with a mid-span that is specially designed to fix both sides of the track together. This prevents outward-bowing of the rails on long runs and provides a fixed structural mounting point which can help with certain vertical setups. Each extension set adds 20" of total length to your slider.
