Allegro 9500 Confined Space 8" Blower Duct
The Allegro 9500 series blower duct is made of a rugged, durable vinyl polyester. It is made to use with 8" blowers. It is constructed with strong external strips, steel wire hoops, and cuffed with an attachment belt. It comes in 15' and 25' lengths. Depending on the blower CFM, lengths can be joined together with a duct coupler.
This duct can also be used with the Euramco UB20 blower if, for some reason, you buy the UB20 without the quick coupler system.
