Machine generates clean grooves for fiberglass ducts

From: CertainTeed Corporation

CertainTeed introduces the Glass Master SG-420 Duct Board Grooving Machine, a powerful machine that fabricates high-quality fiberglass spiral ducts more accurately and up to 50 times faster than standard hand-cutting techniques. The SG-420’s four drive rollers and ¾ horsepower motor provide the necessary grip and power to quickly pull duct board through the 21 tools that are required to form spiral duct liner. Precision-ground and hardened tool blades generate clean grooves and consistent contours and duct dimensions.
