Super Rod Limited
Super Rod Duoxim Arbor

Invented by electrician Kyle Gamble and bought to market by Super Rod, the Duoxim Arbor tools allows tradesmen to enlarge existing holes in seconds - particularly useful for applications where halogen lighting is to be replaced by fire-rated or LED downlights without damaging any of the existing decor. The Arbor even has a universal thread, making it compatible with all traditional hole saws, and it will save time, money and hassle on site.
