One-Hole Compression Lug for 2 AWG

This one-hole compression lug accepts 2 AWG copper wire and terminates it on a 3/4 inch stud. The brazed barrel construction provides mechanical strength for industrial and automotive electrical connections. Rated for 600 volts and a maximum operating temperature of 302 degrees Fahrenheit. UL 467 listed for grounding and bonding applications.

Capacity and headroom for 2 AWG installations

The lug handles a single 2 AWG conductor with a barrel outside diameter of .48 inches and a tongue width of 1.1 inches. Long barrel style allows extended crimp area for secure termination. Tin-plated copper contact resists corrosion in harsh environments. Not suited for wires larger than 2 AWG or applications exceeding 600 volts.

Brazed barrel and tin plating change durability

The brazed barrel seam prevents splitting under high mechanical stress during crimping and service. Tin finish on copper contact surfaces reduces oxidation without requiring additional anti-oxidant compounds. Bare metal insulation coverage means installer must provide separate insulation or heat shrink. Compatible with Grainger part numbers 22P219 and 22P221 for cross-reference.

Questions about this item

Will the 1.1 in tongue width fit the existing 3/4 in stud on my bus bar?

Yes, the lug is built for a 3/4 in stud and the 1.1 in tongue spans the bolt pattern on standard bus bars.

How can I verify the crimp is solid after I compress the .47 in long barrel?

A proper crimp shows full barrel closure with no gaps; the brazed seam should not open and the tin finish remains intact.

Does the package include heat-shrink or any insulation for the bare copper lug?

The lug ships bare with no insulation; you must supply heat-shrink tubing or tape separately.
