Designed by a professional jeweler, the Heetrix Soldering Platform mounts on top of your workbench and the soldering platform swings out of the way when not in use. It also rotates for convenience. The included special third hand attachment with a pair of fiber grip tweezers easily allows for hands-free work. Remove the fitted solderite disc and a depression is revealed which holds soldering grain. It is ideal for holding small parts and may be used wet or dry. Replaceable solderite disc is 3-3/4″ and the overall length with its swing arm is 7″. Made in the U.S.A.
