The Air-Block® is a heavy duty circular floor grommet made with an integrated EDPM gasket material for sealing around cables going through access flooring. This controls bypass air by forming an airtight seal around cables, helping to eliminate air leakage in under-floor air installations.
Features
The Air-Block® is easy to open and even easier to close. The retained center cover forms a solid lid unit when the grommet is not cabled.
The 1 5/8" (42mm) deep grommet fits a 6 inch (150mm) diameter opening in the access floor panel. The Air-Block's revolutionary 2 piece design removes the need for an outer housing ring, and facilitates quick and easier installation of the grommet. The standard flame retardant gasket has 4 optional gasket knockouts. Color: Black
