DEXTER LOCK'S HUGE R I S E R S of Boltaron 6200 a r e shown off the anodizing tanks, going up and through the roof where other Boltaron ducts carry fumes into exhaust fan. " W e a r e well satisfied with the Boltoron 6200 duct system and the service w e h a v e received from the Boltaron Fabricator, Carport Corp., Owosso, Michigan" reported the Company spokesman.
GRAND RAPIDS, MICH. -Boltaron 6200 has done it again. The awesome problem of handling sulphuric acid fumes for months -perhaps years without maintenance, replacement or costly shutdowns has been solved at Dexter Lock Company, a subsidiary of National Brass Company. The answer was and is Boltaron 6200. Highly versatile and readily adapted to complicated shapes, Boltaron 6200 has chemical resistance to both strong and weak organic and inorganic acids, alkalies, alcohol and foodstuffs. It is non-metallic and only half the weight of aluminum. Available in sheet, pipe (and fittings), rod and block stock, Boltaron can be drawn, formed, molded, machined and hot air welded. Whatever your problem, experienced engineers and fabricators coast to coast and in Canada are ready to help you. Write Box 124 for complete information.
