1/2" Dia. x 18" Galvanized Steel Arm Extension - Black
Illuminate large outdoor signs with the 18" galvanized steel arm extensions. Perfect for the PAR 20 bullet directional lamps, these arms are even stronger than their aluminum cousins. These arm extensions are threaded for simple screw on installation to any existing threaded coupling. The black powder coating makes it perfect for both indoor and outdoor use with little weathering or corrosion, so you can apply them anywhere you can hang a heavy duty sign. These particular arms are also available online in other in-stock lighting arm lengths. Call for more details on custom cut arm extensions or to request an illuminating sign bracket.
