Aluminum Heavy-Duty Parallel Clamp - 350 kcmil to 500 kcmil (Main) ; 4 Sol. to 500 kcmil (Tap)

  • Top and bottom castings are manufactured from high strength aluminum alloy
  • Spacer is manufactured from pure high conductivity aluminum alloy
  • Recommended for heavy duty dissimilar metal applications
  • Accommodates a range of aluminum, copper, and ACSR conductors in either groove (place aluminum above copper); not recommended for copper to copper applications unless connector is tin plated
    • For tin plating, suffix the catalog number with “-TN”
  • Specially designed wrap-around finger on spacer minimizes cold flow over entire conductor range
  • Rounded contours for easy taping
  • Staking the longer of the two bolts makes the assembly one unit with no loose parts to drop
  • Use of an oxide inhibitor is recommended for aluminum and ACSR installations
  • Add suffix “-BF” to the catalog number for pre-filling with Cual-Aid and bagging
