Push-on and collet control knobs are now offered with a UV fluorescent and phosphorescent option. UV fluorescent glows under UV light; the phosphorescent—once charged by daylight or artificial light—is visible under dark conditions for a length of time proportional to the amount of charge received. Either option can be incorporated in the white indicator line on all two-shot push-on and two-shot collet knobs whether the outer body is hard or soft touch material. Standard body color is black; other colors are available on request.
