Whatley mast arms are aluminum and have a standard 2-inch NPS (2.375-inch) slip fitter. The slip fitter has a 10-inch long straight end to accept the luminaire.
On contact with air, aluminum forms a protective, corrosion-resistant layer of aluminum oxide. Upon request, a resilient powder-coat finish can be applied to the aluminum mast arm at the factory. Popular colors include black, dark bronze, or grey. Custom colors are available upon request. See color chart below.
Available in 4-foot to 12-foot spans - see table below for details.
