Flush with Frame grilles provide two way diffusion
and are the preferred style for sand and finish hardwood floors where
an architecturally smooth look is desired. Each frame is grooved on the
outside to accommodate most 3/4" tongue and groove flooring. All
grilles are 3/4" thick, with a 1 3/8" wide frame which adds 2 1/4" to
the overall dimension of the grille. Custom thicknesses are available
upon request (20% upcharge).
