Among the more obvious reasons for the use of round duct on rooftops, such as preventing rain, snow and ice buildup, ease of wind passage is perhaps the most overlooked. PhenoliDuct, a new closed-cell insulated round duct solution from Spiral Pipe of Texas (SPOT), is engineered with all those considerations in mind, plus ease of installation.   

Milwaukee Tool introduces the new PLUS-LOK SDS-Plus Extensions for extended reach and deep hole drilling.

The new Mega-Stack option for Greenheck’s Model FJI FumeJet fume exhaust fan offers extended discharge from 10 to 15 feet in overall stack discharge height, making it ideal for low flow applications requiring higher plume rise.
