Up until now we have supplied U-Bands in sizes 4" to 24" for the Powerstack EPS chimney system - for sizes 26" and up, we have used V-band.
An investment in a new custom-made flange roller has greatly expanded our capabilities. We are now supplying U-Bands for ALL chimney sizes and for all our fans and damper with 1/2" flange connections, no matter the material thickness.
