ACGI Grille Systems feature two categories—Grille Backer Series (GB) and Grille Dowel Series (GD). Both systems are available in solid wood or wood veneer (depending on blade size and design requirements). Blade sizes are typically 13/8"–31/2" deep (for depths greater than 31/2" see our Baffle Systems). Grille panels are assembled with four to ten blades per foot. Panels are nominal 1' or 2' width by varying lengths in 1' increments (custom widths and lengths are available).

Grille Backer Series 1 [GB1] is panelized with factory-attached wood backers at 12" O.C. Backers are painted flat black (other finishes are available). GB1 panels install by screwing through the backers between blades. Ceiling applications are suspended from 15/16" HD T-Grid, and attached to walls using sheathing or furring strips. Panels are installed with 1/2"–1" reveal between panel ends and at perimeter walls or headers. Optional notched backers provide additional strength and stability for wall applications with blade depths greater than 2". For post-installation access the attachment screws can be removed, or optional suspension can be provided for regular access.
