Nordfab’s Quick-Fit® is often used for concrete dust applications because it is quick and easy to install. Quick-Fit clamp-together ducting eliminates rivets, screws, welds and flanges. The clamp-together design allows installations, clean-outs and changes to take only a fraction of the time it takes for traditional ducting. Nordfab Quick-Fit’s longitudinal seams provide smooth, no hang-up interiors.
