BRUSHGLAND Floor Gland
The Floor Brush Gland/Grommet offers dramatic performance enhancements
- A unique concept that improves on the inadequacies in old fashioned floor grommets
- Simple to Retro-fit
- Surface or under tile mount fitting
- Drop in “All-in-One” Cable Management & Air-Blocking System
- Power/Data Partition (optional extra)
- Quick Fit removable Brush to ease access
Features and Benefits
- The brush is Quick-Fit, Quick-Release removable allowing access through the gland, to under floor
- 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 root of the brush where poor distortion will occur)
- This patented orientation of the brush dramatically improves air blockage and supports the brush droop over time
- Bend radii and cable tie points avoid corrupted data and simplify installation
- One gland can be either "surface mounted or drop in" (into the cut out in the tile) or retro-fit around pre-installed cables reducing the range of glands required
Unique Brush GlandThe 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.

BRUSHGLAND Floor Gland
Cold air pressure should not lift the brush strip seal and escape through the gland
- Hot air should not be drawn downwards, below the tile and into the cold air flow
- Two issues are of significant importance to separate Cold and Hot Air via any grommet
- Note: IPACK 2001-15728ASME advises that grommet/tiles near the CRAC unit often experience negative air flow from inside the rack, pulling hot air down into the cold air stream.
- BRUSHGLAND grommets have been laboratory tested and brushes did not lift or flap until an air pressure of 1500 pascals (0.44″ water gauge) was reached. Underfloor static pressure is commonly 6 pascals (0.025″ water gauge).
- BRUSHGLAND grommets substantially exceed the common static pressure with a high safety factor.
