LDN Pad: HD Concave (blue): smooth pad (.289 hole). PADS: deflector pad options (smooth, grooved, medium groove, or deep groove) each deliver a different spray pattern and droplet size. Each surface is also available in three basic geometries based on the desired trajectory of throw – concave (blue) for a slightly upward spray, flat (black), and convex (green) for a slightly downward spray.
