Aluminum Dove Tail is a popular architectural style for its aesthetic appeal and ability to maintain tight tolerances. Dove Tail panels are constructed using precision slotted bearing bars and crossbars that are assembled in egg-crate fashion and hydraulically pressed together to form a tightly locked grid. This grating is available in 1/4″ or 1/2″ openings with our Grater Access® option to select 2″ or 4″ centers for ADA compliance.
