One must have in any fabrication shop is a shrinker/stretcher. The MSS-18 is Baileigh Industrials entry level shinker/stretcher, but we take the base unit and add some kick to it, literally. Instead of having to buy an optional stand like most other seller; we include it in the price. And whats better, we made it a kick stand. Thats right; with the MSS-18 both hands will be free to handle the material. Another feature of Baileigh Industrials MSS-18 sheet metal shrinker/stretcher is that ours has one complete shrinker and one complete stretcher both in their own cast iron housings. No need to switch out jaws if you need switch functions. The heavy casting assures a quality function at full capacity, which is 18-gauge in mild steel and 16-gauge in aluminum. \n \nThe MSS-18 metal shrinker/stretcher units are constructed of cast iron to last the fabricator for years of production. Replaceable jaws can be ordered separately as needed.
