This 6"x6" square, Soft Solderite™ Pad/Board allows you to easily push in pins, heads or components for quick and easy alignment. Composed of calcium silicate, the same material as original (hard) Solderite and will provide the same superior heat reflection, insulating qualities and fast cool-down time. They won’t easily break, crack or crumble as so many other soft products will. Asbestos-free, OSHA approved. Measures 3/4" thick. Fits our 8302228 (a handy rotating square soldering table which permits 360° access to your parts so that you can solder quickly and easily. Bearings in the base provide smooth, easy movement).
