Blackburn QCO21 – Frequently Asked Questions
1) What conductor sizes does the Blackburn QCO21 compression stirrup take?
The QCO21 is built for 2/0 through 2 ACSR run conductor, which is where the "2/0-2 ASCR" in the part name comes from. It is a compression connection, so the run side is crimped onto the cable rather than bolted. If your run falls outside that 2/0 to 2 ACSR band, you need a different stirrup size.
2) Is the QCO21 stirrup aluminum or copper?
Aluminum body. That makes it suited to aluminum and ACSR run conductor, matching the 2/0-2 ACSR range it is rated for. For an all-copper run you want a copper or bimetallic connector instead, since aluminum-to-copper contact needs a transition-rated fitting.
3) Does the QCO21 come insulated, or do I have to cover it after crimping?
It ships bare, with no insulation on the connector. Any covering, tape, or insulating boot over the finished connection is a separate item you add on the job.
4) How much room do I need to fit a QCO21 stirrup in a compact space?
Plan for a footprint of 8-3/4 x 3-1/8 inches. That is a sizeable fitting, so check clearance to adjacent phases and to the crossarm or enclosure wall before you commit the crimp.
5) What is a compression stirrup actually used for on a distribution line?
A stirrup gives you a dedicated tap point so hot-line clamps and tap connections land on the stirrup instead of the main conductor, keeping repeated clamping off the run. The QCO21 is the compression style: it is crimped permanently onto a 2/0-2 ACSR run as a wire or cable compression splice, rather than bolted on.
6) Is the Blackburn QCO21 sold individually or in a box?
Sold each. Order the exact count you need for the job rather than a carton quantity.
7) What part number and origin should I put on my purchase order for this stirrup?
Order it as Blackburn QCO21. Country of origin is Mexico, which is the detail most utility and municipal buyers need for their procurement paperwork.
