Model DDF-G Series Grilles—

Model DDF-GF grilles have a mitered, offset, galvanized sheet metal (optional paintable galvanized steel, 304 and 316 stainless steel, and aluminum) frame for easy installation on a round, flat oval, or rectangular duct assembly or fitting body using sheet metal screws.

The Model DDF-GOBD grille (not available in aluminum) incorporates an integrated, opposed blade damper for balancing volume flow rates among grilles.

There are 31 standard sizes. The Model DDF-GF grille can be field or factory installed. Factory-installed units incorporate closed cell foam gasketing for a dust-free seal.
