The Strategy Series FA-TR8 trim ring/rough-in bracket, for wall or ceiling-mount applications, installs prior to the drywall and serves as a pattern cut-out for the drywall contractor to finishout the wall leaving the proper opening for a FA97-8 or FA95-8 enclosure or FAPR-8 plaster ring. This step identifies pre-wire location and expedites sound system installation. Trim ring measures 25 5/8" L and will accommodate 3/8" to 1 1/4" drywall. Mounting holes are provided to match both 16" and 24" center studs. FA-TR8 is constructed of #18 gauge galvanized steel. NOTE: Trim ring alone will not allow installation of Strategy Series Grilles. Enclosure or FAPR Plaster Ring is required for grille installation.
