Unique Brush Gland

The Cannon brush gland is pre-stressed to resist air  pressure.The patented system provides firm  support to both ends of the brush; the brush tips press down onto the radiused sides of the  grommet, acting like leaf springs.This imparts  greater resistance to air pressure.

  • The brush is “Quick-Fit” and Quick-Release removable, allowing access through the gland to under floor void
  • The brush is mounted on a central bar so that the tips of the brush rest on the sides of the gland where the brush is not heavily distorted by cables
  • Cables do not pass through the middle of the brush where increased distortion will occur
  • This patented orientation of the brush dramatically improves air blocking and supports the brush to prevent brush sag over-time
  • Bend radii and cable tie points around the edge, avoid data cable damage and simplify installation
  • BRUSHGLAND can be either “surface mounted”, “drop in” (into a cut out in the tile) or retro-fit around pre-installed cables, reducing the range of glands required to fit in a pre-cut tile
  • The BRUSHGLAND has quick release features for instant separation of the frame when retro-fitting, so no tools are needed
  • For Drop-in mode, the skirt of the gland protects data cables from sharp metal at the lower cut edges of the tile and provides bend radius at the lower and upper edges to protect data cable integrity
  • An optional Data/Power Partition is available to separate power cable from data cable by the required amount, to protect against data  corruption
  • The separator bridge just drops in after large power connectors have been passed through the gland, so any size of pre-terminated connectors can be used

Fibre optic cable can be introduced through the  bridge to utilise the data separation space  effectively. This maximises gland capacity without  endangering data integrity


  • Provides a higher level of air blockage when compared to other cabled grommets
  • Is more protective of fragile data cable
  • Separates power cable from data cable
  • Is much more user-friendly
  • Provides visual and physical access to the underfloor
  • One BRUSHGLAND™ achieves all of the install needs i.e. Surface Mount,    Drop-In or Retro-Fit


  • Cut-out size in floor tile: 270mm x 185mm (10 5/8” x 7 5/16”)

  • Overall dimensions: 296mm x 210mm x 40mm (11 3/4” x 8 1/4” x 1 9/16”)
  • Height above floor tile when fitted into floor tile: 3mm (flange thickness) (1/8”)
  • Height above floor tile when fitted above floor tile: 40mm (1 9/16”)
  • Height of Power/Data Partition ‘ears’ (when fitted) above Floor Gland flanges: 20mm (3/4”)
