New Duct Board Equipment From CertainTeed
The fiber glass machinery brand has introduced the Glass Master SG-420 Duct Board Grooving Machine
CertainTeed Machine Works has introduced 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 required to form spiral duct liner. Precision-ground and hardened tool blades generate clean grooves and consistent contours and duct dimensions.
Like CertainTeed’s Glass Master SG-220, the SG-420 can be easily adapted to groove 1", 1 ½" and 2" boards. Its square duct tool holders include a unique measuring tab for easy and accurate groove spacing, and quick-release clamps on all tools allow for fast repositioning. Standard features include a foot-actuated switch for safe operation, four swivel casters and a durable powder coat finish.
The SG-420 not only simplifies the process of creating spiral duct systems with top-quality square and rectangular ducts but also enables contractors to easily manage even the most complex spiral duct projects.
