This Articulating 9 Roller Hose Guide pivots in the middle to allow you to use it on exposed corrugated pipe that can cut your hose. When you jet below an elevated road you need to protect your hose around the curve going into the drainage pipe. This roller will guide your hose over the top and make the bend into the pipe while protecting it from the sharp corrugated pipe.
