Cush-A-Block

Cush-A-Block duct supports utilize Cush-A-Block bases with Unistrut channel and fittings to provide elevated supports on flat roofs. The Cush-A-Block system provides economical support for gas piping systems, electrical conduit, HVAC equipment, and many other applications. UV resistant and suitable for installation on most types of roofing material or other flat surfaces, Cush-A-Block can also be used as a curb (sleeper) replacement.
