Blackburn 2B20BB – Frequently Asked Questions
1) Does the Blackburn 2B20BB come with a spacer?
No. The 2B20BB is the no-spacer version (the "W/O SPCR" in the description). If your run pairs a smaller conductor against a larger one and you need a spacer to fill the clamp and keep even pressure, you need a spacer-equipped catalog number instead of this one.
2) Can I use the Blackburn 2B20BB on aluminum conductors?
No. This is a copper-bodied connector and the catalog number designates it CU, so specify it for copper-to-copper connections. For aluminum or mixed AL/CU work, you need a dual-rated connector, not this one.
3) What is the bolt size on the Blackburn 2B20BB copper connector?
The connector uses 1/2 inch hardware, which is the "1/2B" call-out in the part number and matches the 1/2 inch outside diameter listed on the spec. Two bolts clamp the conductors, so torque both evenly when you make the connection.
4) Do I need a crimping tool for the Blackburn 2B20BB?
No crimper required. This is a mechanical bolted connector, so it is made up with a wrench on the two 1/2 inch bolts. That makes it workable in a panel or pull box where you cannot get a hydraulic crimp head in, and it can be taken apart later if the tap changes.
5) Is the Blackburn 2B20BB sold individually or in a box quantity?
It is sold each, one connector per selling unit, under manufacturer part number 2B20BB. Order the count you need for the job rather than a carton.
