Tile bridges are often required, for safety reasons, by local building codes, and for aesthetics to reduce the potential of unsightly ceiling tile sag. Lowell tile bridge Model LUH-TBAR is engineered specifically to distribute the Unihorn assembly (LUH-15T) weight (6 lbs) to the ceiling support system when installed in a suspended 2' x 2' or 2' x 4' tile ceiling system. The horn installs to the tile bridge using screwdriver adjustable clamps (dogs).
