The Allied Bolt Strand Splice (vendor part AB504000, Millennium part 528766) joins 1/4 in extra high strength strand between .215 in and .270 in diameter, holding up to 90% of the strand's rated breaking strength for messenger and guy wire runs. It lets aerial crews repair or extend strand mid-run on a fiber pole line without swapping to a heavier gauge just to add a splice point. Boxed 50 per carton for production-scale construction work. Millennium also stocks the matching 3/8 in and all-grade splices plus deadend hardware for the same strand sizes.
