CoolBalance - Circle Seal
The CB33 circular surface-mount cable seal consists of a single brush spiral and a holder. The geometry of the brush provides an intrinsically more efficient seal, completely surrounding the cables. Additionally, polygonal filaments are used which nest and interlock to provide a more effective brush seal than brushes constructed with ordinary round filaments.
The CB33-04 or CB33-06 series include a single-piece holder for new installations where cables have not yet been installed. The CB33S-04 or -06 (S = split ring) surface-mount cable seals come with a two-piece holder enabling installation around existing cable. CB33EP utilizes a 2 in./50.8 mm long PVC pipe to provide edge protection (EP).
Using our patent pending Dyna-Seal™ technology, the CoolBalance brush seal provides the most effective seal to prevent the leakage of pressurized air around power and communications cables in floor cutouts.
