Blackburn PAE9999-9 AL PARAGRV CLMP EXTRUDED 1000-397

Two. The PAE9999-9 is a two-conductor parallel-groove clamp, so it joins one run conductor to one tap (or two runs side by side) in its grooves. If you need to land more than two cables at one point, you need multiple clamps or a multi-conductor connector instead.

Plan for a footprint of 2-13/16 x 6 x 2-13/16 inches (height x length x width) plus wrench clearance around the 1/2 inch bolt. On tight risers or crowded ground bars, measure before you commit, because this is a substantial extruded body rather than a small compression sleeve.

The body is extruded aluminum, which is what you want for aluminum-to-aluminum connections. Aluminum bodies are widely used on aluminum conductors and on combination taps, but a direct aluminum-to-bare-copper connection needs a connector rated for that dissimilar pairing, so confirm the conductor materials on your run before you set this one.

It is a bolted clamp with a 1/2 inch bolt, so bring a socket or wrench for a 1/2 inch hardware size and a torque wrench if the job spec calls for a torque value. No crimp tool or die set is involved.

A bolted parallel-groove clamp like the PAE9999-9 is mechanical: you can install it with hand tools, inspect it, and take it apart later if the run changes. Compression connectors need the matching tool and die and are permanent once crimped. Pick the bolted clamp where you want a serviceable, re-enterable connection or where no crimp tool is on site; pick compression where the spec demands an irreversible splice.

No insulation on it. The PAE9999-9 is a bare extruded aluminum clamp, so if the connection sits where it needs covering you have to add tape, a boot, or a cover as a separate item.

Each. The selling unit is one clamp, ordered by the model PAE9999-9, so you can buy the exact count a job needs rather than a carton.
