EyeLine Golf Edge Putting Plane Rail (70-degrees)

The rail is set at a 70 degree lie angle to fit almost all standard putter angles. When you swing the putter on a flat surface, it opens and closes the putter face slightly, making it square at impact. Professional grade materials - lighter and more durable than ever. The putter glides smoothly over this thermoformed plastic rail. Markings on the rail surface - Check the putter's back and through distance and shaft rotation. Make more putts - The putter moves like it's assembled - it rises on the rail as you bring the putter into your backswing. Move slightly inside the line and return straight to the ball. Perfect for practicing indoors or outdoors. Tee down outdoors or use the non-slip bottom to secure it on carpets, rugs, or putting mats.
