Aluminum Dovetail Grating is a type of pressure locked bar grating that offers a rectangular crossbar that is flush with the top surface of the rectangular bearing bars. The bearing bars are available in 7 different depths ranging from 1" to 2-1/2". Dovetail grating is offered in either 1-3/16" (19-spacing) or 15/16" (15-spacing). This style of grating is widely used in architectural applications due to its clean appearance and its flush top surface. Note: Grating does not include end banding.
