February 21, 2013 – Randl Industries says the added width and volume of the 5 Square fire signal box eliminates ground faults and short circuits by doing away with pinch points and overcrowding of the appliance and conductors, subsequently eliminating associated troubleshooting time. The 5 Square x 4 square plaster ring mounting holes are precisely stamped and tapped, allows for quick installation of the appliance. The physical size of the box makes wire pulling much easier, adds the company, and saves knuckles from being skinned and cut as often.
