Available now the Dynamic Thin Line Fire Damper (DIBDT). The DIBDT is built with a thin line frame that is 3 1/2" deep and includes two 5/8" channel flanges for ease of installation without fasteners within the blade channel or tack welds to install in sleeves.

The DIBDT 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 Dynamic curtain fire damper installed in a 24 gauge register box with rear steel collar for ducted applications and an aluminum supply or exhaust grille.
