Mechanical Connector for Aluminium and Copper

The Thomas & Betts Blackburn ADR35-22 is a mechanical lug rated for stranded copper conductors from 6 AWG up to 350 kcmil. It also accepts aluminium conductors in the same range. The body is aluminium and the connector carries a 1,000 V maximum voltage rating for industrial and automotive wiring.

Installation uses a hex socket on a two-hole tongue

The tongue measures 3 in long, 2.3 in wide and 0.31 in thick with two mounting holes of 0.5 in diameter spaced 1.22 in apart. A hex socket head allows tightening with a standard driver. Ensure the conductor is fully seated and the set screws are torqued to the manufacturer’s specification to avoid loose terminations.

Rated for 350 kcmil maximum conductor size

This single limit decides whether the lug matches your cable. It accommodates two conductors per termination and operates up to 194 Degrees F. Buyers needing a larger conductor range or a different stud size must select an alternative lug.
