Blackburn PAA12-B1 PAA12 WITH INNER PACK 1 PIECE BAG

Bolted. The PAA12-B1 uses a 1/2 inch bolt with a 3/4 inch bolt head, so you install it with a wrench or socket rather than a hydraulic crimp tool. No press, die set, or crimp head is needed on the job.

A parallel-groove clamp joins two conductors running alongside each other, either as a splice or as a tap off a main run. The Blackburn PAA12-B1 is used for wire or cable splicing in grounding and bonding work, with the two conductors seated in the grooves and drawn together by the bolt. If you need to bond to a ground rod, water pipe, or steel surface instead, that calls for a rod clamp or pipe clamp, not a parallel-groove type.

The PAA12-B1 body is aluminum. Aluminum-bodied parallel-groove clamps are the standard choice for aluminum-to-aluminum runs such as overhead or service conductors. If your connection involves copper, confirm the clamp you order is rated for the specific combination of metals you are joining, since dissimilar-metal contact needs a connector qualified for that duty.

The body measures 2-1/4 inch height by 2 inch length by 2 inch width, and you need wrench clearance for a 3/4 inch bolt head on top of that. Worth checking against pull box or handhole space before you spec it for a crowded termination.

It is a bare clamp with no insulation material, so the completed splice is exposed metal. If the connection needs to be insulated or protected, plan on tape, a cover, or a sealed enclosure as a separate item.

A 3/4 inch wrench or socket covers it, matching the bolt head on the 1/2 inch bolt. Nothing else is supplied with the clamp, so conductor prep such as wire brushing and any joint compound comes from your own kit.

The B1 suffix means it is packaged in a one-piece bag inner pack, and the clamp is sold each. Order the quantity of individual clamps you need rather than counting on a bulk box.
