New Glass Master SG-420 Machine from CertainTeed Grooves Spiral Duct Liners in Seconds
(MALVERN, Pa.) – CertainTeed Machine Works, a division of CertainTeed that offers a comprehensive line of commercial and residential insulation and fireproofing application equipment, has expanded its line of duct board grooving equipment with the new Glass Master SG-420 Duct Board Grooving Machine – a powerful machine that fabricates high-quality fiberglass spiral ducts faster and more accurately than ever – up to 50 times faster than standard hand-cutting techniques.
The SG-420’s nine drive rollers and ¾ horsepower motor provide the grip and power to quickly pull duct board through the 21 tools required to form spiral duct liner. Precision-ground and hardened tool blades produce clean grooves and consistent contours and duct dimensions.
“Creating spiral duct systems has been a challenge for many contractors, but now, it doesn’t have to be. Our new SG-420 machine provides the same industry-leading performance they’ve come to expect from CertainTeed Machine Works equipment in a much more versatile machine,” said General Manager Blair Gaida. “The SG-420 not only helps them create top-quality square and rectangular ducts, it also lets them tackle even the most complex spiral duct projects.”
Like the Glass Master SG-220 machine, the SG-420 is easily adaptable to groove 1", 1 ½" and 2" boards. Its square duct tool holders have a unique measuring tab for easy and accurate groove spacing. Quick-release clamps on all tools allow for fast repositioning. All machines come equipped with a foot-actuated switch for safe operation, four swivel casters, and a durable powder coat finish.
