The Allied Bolt Crossover Clamp (vendor part 4065, Millennium part 528233) joins two strands from 1/4 in to 3/8 in perpendicularly at mid-span, using three 1/4 in x 3/8 in bolts to secure crossing messenger or guy strand on aerial builds. Ductile iron construction with hot-dip galvanizing to ASTM A153 holds up under continuous tension where strand runs cross on a pole line. Boxed 25 per carton for production aerial construction. Millennium also stocks E span and figure-8 clamps for other strand crossing configurations on the same job.
