Blackburn LAC42 Aluminum Compression Terminal Lugs

Blackburn LAC42 Aluminum Slotted Tang Compression Terminal Lug, sold in a 10-pack, is a color-coded orange lug designed for two-slot, slotted-tang terminations on aluminum and copper conductors. It accepts conductor sizes including #4 stranded, #4 solid, and #3 solid, with two slots to accommodate either stranded or solid conductors, and uses standard installation dies BY37, 840U for concentric/compressed seating and B49EA, K840 for final seating. The lug is part of the Blackburn/Homac line of compression connectors and is listed for rugged field use; a boss on the lug fits the indent on the bus to prevent rotation, enabling the bus to remain installed during termination. This design reduces installation time and provides a secure, low-resistance connection in distribution panels, feeders, or other high-current applications where corrosion resistance and reliable termination are important. The LAC42 is color-coded orange to designate the 4 AWG conductor range, and it appears alongside related lugs in ABB’s color-keyed Blackburn lineup of aluminum compression lugs.
