Blackburn AL 2-38 AL 1HOLE NEMA LUG CONCENTRIC 2

The AL 2-38 is sized for #2 STR AWG conductor. One conductor per lug, and it is a compression fitting, so it has to be crimped with the correct die for the barrel, not bolted or set-screwed.

One hole. The AL 2-38 lands on a single bolt, which suits breaker lugs, ground bars and busbar pads drilled for one fastener. If your equipment pad is drilled on NEMA two hole spacing and the spec calls for two bolts per termination, a one hole lug will not meet it, and you need the two hole version of the same wire size.

The AL 2-38 is an aluminum-bodied lug. Many aluminum compression connectors are dual rated AL9CU, but rating for copper is not something to assume from the body material, so match the conductor to what the barrel is marked. For a straight #2 copper run, order a copper compression lug in the same one hole configuration.

It is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. That is the reference most utility and commercial electrical specs cite for compression connectors, so it is the line to quote on a submittal.

Overall length is 2-5/8 inches. In a tight gutter or a shallow panel, measure from the bolt hole back past the crimp barrel and add the conductor bend radius before you commit, because the barrel is where the length goes on a compression lug.

Country of origin is the United States, which is what a government, school or federal project submittal typically needs documented for domestic sourcing requirements on electrical material.

A compression lug like the AL 2-38 is crimped once with a die and tool, giving a permanent termination with no torque to re-check later, which is why specs favour it on feeders and utility work. A mechanical set screw lug installs with nothing but a hex key and can be reused, but it has to be torqued to spec and is often retorqued at inspection. Pick compression when you own the crimp tool and the termination is permanent.

The AL 2-38 is sold each, so you can buy the exact count the job needs rather than a bag. Order one per conductor termination, plus spares for miscrimps, since a compression lug is not reusable once it is crimped.

Order it as Blackburn AL 2-38, a one hole NEMA compression lug for #2 concentric stranded conductor. That MPN is what identifies the wire size and the single bolt hole together, so quoting it avoids getting a two hole or a #1/0 barrel by mistake.
