Circular brush seal providing superior air sealing performance.

The unit comprises of 3 parts:
1. Outer Ring Housing with quick locking clamping arms (no additional drilling once the opening is formed.)
2. Brush Ring Insert – cables can be installed through the grommet without the brush in place. Once cabling is completed the dense brush ring can be opened to encase the cables. The ring is then fitted into the outer housing.
3. Top Flange – the two semicircle flanges fasten together to form an attractive top flange which conceals the rim of the brush ring and fits into and over the support flange of the outer housing.

As the bristles are concentrated towards the centre of the grommet they form a dense brush seal which encapsulates cables forming a practical air seal. The opening is large enough to facilitate almost all cabling requirements.
