The secondary rack extension bracket mounts to utility poles in pairs to support secondary racks at an offset distance from the pole, typically 6 inches. This offset provides clearance for transformers and other equipment while maintaining proper wire alignment for electrical distribution. The bracket’s curved back, 3 inches wide, fits snugly against the pole surface to maximize bearing area and stability.
Constructed from heavy-duty steel with hot dip galvanizing per American Society for Testing and Materials (ASTM) A153, the bracket resists corrosion, moisture, and chemical exposure in outdoor environments. It meets American National Standards Institute (ANSI) C135.7 specifications and exceeds strength requirements for medium and heavy-duty applications in power distribution infrastructure.
Mounting slots accommodate 5/8″ bolts, with staggered holes allowing alternative installation using 1/2″ lag screws. A groove retains a square nut, enabling installation over existing bolts without disturbing current setups. The bracket typically measures 8 inches long, 3.9 inches wide, and 4 inches high, weighing approximately 2.68 pounds. Standard hardware includes a 5/8″ x 2″ carriage bolt for secure pole attachment.
