Blackburn PAA6 AL PARAGRV CLAMP 1-2BOLT 2/0-8

The PAA6 covers conductors from 2/0 through 8 AWG, as called out in the model description ("2/0-8"). It holds two conductors, one in each groove, so you can tap or splice a run anywhere in that range without changing clamps.

The PAA6 body is aluminum. Aluminum-bodied parallel groove clamps are intended for aluminum conductor connections; putting bare copper directly against aluminum creates a dissimilar-metal joint that corrodes. For a copper-to-copper or copper-to-aluminum ground connection, use a clamp rated for those combinations rather than a plain aluminum body.

It is a one-to-two bolt parallel groove clamp using 3/8 inch bolts with a 9/16 inch hex head, so a 9/16 inch wrench or socket does the tightening. No special tooling or crimper is needed, the connection is bolted.

Plan on a footprint of 2-7/32 inch height by 1-3/8 inch length by 1-5/8 inch width, plus wrench swing for a 9/16 inch head. That is the envelope to check against tight gutters, meter sockets, or a crowded riser before you commit.

A parallel groove clamp like the PAA6 is a bolted, reusable joint: you can open it, reposition a conductor, or add a tap later with hand tools. A compression splice is permanent and needs a die-matched crimper. Pick the bolted clamp when the connection may be inspected, re-terminated, or made in the field without press tooling; pick compression when you want a sealed, non-adjustable splice.

Order Blackburn PAA6. That is the manufacturer part number for the aluminum parallel groove clamp covering 2/0 through 8 AWG with two conductor grooves and 3/8 inch bolts.

It ships bare, with no insulating cover or boot. On a grounding or bonding conductor that is normally fine. If the clamp lands where an energized or protected joint has to stay covered, plan on your own insulating tape or cover as part of the install.

Each PAA6 clamp is sold as a single unit rather than by the box, so you can order to the exact count on the job. Country of origin is the United States.
