The Crossarm Mounted Cutout & Arrester Bracket securely mounts electrical equipment such as cutouts, surge arresters, and cable terminators on wood or fiberglass crossarms in overhead distribution systems. Multiple models accommodate different crossarm dimensions, with variants fitting 6-inch high crossarms or 4-inch by 6-inch configurations. Extension lengths range from 2-3/4 inches to 4 inches, with designs tailored for applications including NEMA B Type Easy-On configurations.
The bracket features steel plate construction with hot dip galvanizing per ASTM A-153, providing a zinc coating that enhances resistance to environmental factors. The steel is free from sharp edges, burrs, and cracks to ensure reliable field performance. Common dimensions include a 5/16-inch by 1-1/2-inch profile, with exact specifications detailed in engineering drawings for each model.
Compliance includes the latest revisions of Institute of Electrical and Electronics Engineers (IEEE) C37.42 for distribution-class fuses and cutouts, IEEE C135.1 for zinc-coated steel bolts, and American Society for Testing and Materials (ASTM) A-153 for zinc coating specifications. Each bracket bears permanent manufacturer marking for traceability and identification.
Accessory hardware typically includes a press-fit captive carriage bolt (1/2-inch by 1-1/2-inch or 3/8-inch by 6-inch) assembled with hex nut, external tooth lock washer, and split lock washer. Some models include additional carriage bolts and washers for crossarm mounting, while others allow for user-supplied hardware based on installation requirements.
