Conduit Riser Junction/Support Boxes
Flash Technology junction/support boxes provide field-proven and water-tight enclosures for conduit runs and vertical wire support. Each cast aluminum box is seam free to minimize corrosion, prevent leakage and offers maximum protection. Since the insulated wire supports are factory installed, NO additional wire support fittings or devices are needed to meet the requirements of the National Electrical Code for individual wire sizes #6 gauge and smaller. Interior conduit entry bushings prevent damage to wiring due to chaffing during installation or natural vibration. Oil resistant gaskets and adhesives are utilized to provide superior protection in all outdoor areas where wind driven or freezing rain, salt air, dust, and dirt problems are prevalent. Stainless steel bolts are evenly spaced on all (4) sides of the cover to assure an unbreakable, watertight seal. A multitude of conduit sizes from 1/2” to 2” NPT can be accommodated.
