Sigma's weatherproof round boxes provide a junction for conduits and can be used to mount lampholders and lighting systems in outdoor applications. The rugged, die-cast construction prevents moisture penetration making the boxes suitable for wet, damp or dry locations. These UL and CSA listed boxes are powder coated for maximum corrosion resistance and feature reinforced connector outlets for secure installation. Mounting lugs, closure plugs, and a pre-installed ground screw are included.
