Larger IBDT Horizontal Sizes and the ABD-FD (IBDT)
Ruskin® has increased the over-all size of the IBDT Thin Line Fire Dampers to 36" x 36". This increased the height from 12" to 36" tall (33% larger). The IBDT, IBDT1 and IBDTG are perfect choice when space is an issue and a fire damper is required per the building codes.
ABD-FD (IBDT)
The IBDT dampers are also used in conjunction with the ABD-FD assembly. The ABD-FD is the only UL listed assembly with the auto balancing damper. The ABD-FD is factory supplied with a curtain fire damper installed in a 24 gauge register box with rear steel collar for ducted applications and an aluminum supply or exhaust grille.
