A suspended ceiling comprising a pair of parallel main grid tees, the tees being of the type having its panel supporting flange forming a hollow with a downwardly open slot, a plurality of identical stabilizer bars spacing said main grid tees a predetermined distance, trim strips assembled on said main grid tees, the trim strips each having a first portion hooked into the hollow flange of a respective tee and a second portion abutting a web of the respective tee, the stabilizer bars being arranged to engage opposite sides of reinforcing bulbs of the main grid tees to hold the same against relative lateral horizontal movement from their desired positions, the stabilizer bars engaging the trim strips in a manner that holds their second portions in abutment with the webs of their respective tees. The stabilizer bars are formed of sheet metal and have bendable tabs that can be bent to hold said trim strip second portions in contact with the webs of their respective tees. The trim strips have a G-shaped profile that is adapted to receive portions of cross tee connectors assembled through slots in the webs of the main grid tees.
A suspended ceiling comprising a pair of parallel main grid tees, the tees each having an upper reinforcing bulb and vertical web below the reinforcing bulb and being of the type having its panel supporting flange forming a hollow with a downwardly open slot, a plurality of identical stabilizer bars spacing said main grid tees a predetermined distance, trim strips assembled on said main grid tees, the trim strips each having a first portion hooked into the hollow flange of a respective tee and a second portion abutting a web of the respective tee, the stabilizer bars being arranged to engage opposite sides of reinforcing bulbs of the main grid tees to hold the same against relative lateral horizontal movement from their desired positions, the stabilizer bars engaging the trim strips in a manner that holds their second portions in abutment with the webs of their respective tees.
A sheet metal stabilizer bar for maintaining a predetermined horizontal spacing between a pair of parallel grid tees, the stabilizer bar being a thin walled elongated body with longitudinally extending portions lying in imaginary planes that are parallel to the longitudinal direction of the bar and that intersect one another, each end of the bar having a cutout area for receiving the reinforcing bulb of a grid tee, the cutout area at each end being configured to lock onto the bulb of a grid tee by pivotal movement of the stabilizer bar relative to the grid tee about the longitudinal axis of the grid tee in a manner that restricts relative movement of the stabilizer bar and grid tee vertically and horizontally relative to the grid tee.
An elongated straight trim strip for covering the side of a web of a grid tee of the type having a downwardly open C-shaped channel formed by its ceiling panel supporting flange portions, and grid tee connectors assembled into the web from a side opposite the side being covered, the trim strip having a generally constant cross-section along its length, the cross-section including a hook adapted to engage a portion of an upper surface of a lower horizontal in-turned flange portion of the grid tee, a horizontal wall adapted to extend under the flange portion being engaged by said hook, a generally vertical wall extending upwardly from said horizontal wall and a generally horizontal flange extending from the vertical wall adapted to engage the web of the grid tee, a combined height of the vertical wall and the width of the horizontal flange being sufficient to receive the projecting end of a connector of a cross tee extending through the web of the tee to which the trim strip is attached.
