Blackburn ATL5002 500 AL TP COMP LUG 2HL 1/2IN PNK

The ATL5002 is sized for 500 kcmil conductor. It's a one-size compression lug, so it isn't a range fitting: 500 kcmil cable only, and the barrel must be crimped with the matching die for that size. The pink color coding on the barrel is the size identifier, which is how you confirm the right lug on a panel full of terminations after the fact.

Yes. The pad is drilled two-hole for 1/2 inch hardware, so it lands on a bus or ground bar with 1/2 inch studs or bolts. Two-hole means the lug can't rotate under torque or fault current, which is why it's specified on service equipment and switchgear pads rather than a single-hole tongue.

Crimp tool. This is a compression lug, not a mechanical set-screw lug, so termination is a hydraulic or battery crimper with the die matched to 500 kcmil aluminum. If you'd rather torque a set screw than own the tooling, you want a mechanical two-hole lug instead. Contractors often stock both: mechanical for one-off service work, compression where the spec calls for it.

Sold each. For a three-phase-plus-neutral 500 kcmil feeder termination you'd be counting four per end, eight for both ends, so order the piece count your terminations require rather than assuming a multi-pack.

Pink is the color code that identifies the conductor size on this lug, 500 kcmil. It is how a crew picks the right barrel out of a bin and how an inspector or the next electrician verifies the termination matches the cable without cutting anything apart. Match the die color to the lug color when you crimp.

Blackburn ATL5002, a 500 kcmil aluminum two-hole compression lug with a 1/2 inch stud pad, made in Mexico. That's the manufacturer part number to put on the purchase order and the submittal sheet; Blackburn is the sub-brand label it's marketed under.
