The Crossarm Mounting Bracket securely attaches distribution stringing blocks, cutouts, lightning arrestors, and cable terminators to crossarms in utility electrical infrastructure. Quick-release mechanisms with hook nuts or pins enable easy attachment and angle adjustment of mounted equipment, enhancing installation and maintenance flexibility. The lightweight design facilitates handling and transport while maintaining strength and safety through secure mounts that resist displacement under load.
Construction typically uses galvanized steel per American Society for Testing and Materials (ASTM) A-153 standards, with 1/2-inch carriage bolts for fastening. Brackets accommodate crossarm sizes including 4-1/2 by 5-1/2 inches and 6-1/4 by 7 inches, with maximum dimensions supporting widths up to 5.7 inches and heights up to 6.3 inches. Safe working loads reach 2500 pounds, with minimum ultimate strengths ranging from 1750 to 3500 pounds.
Weight ranges from approximately 3.5 to 5.25 pounds, with shipping dimensions around 7 inches in length, width, and height. Style variations include full frame and partial frame options, featuring straight ball detent pins or L-shaped locking detent pins. Dimension tolerances are within +/-5%, and rentable models offer practicality for temporary projects. Detailed data-sheets are available upon request.
