Blackburn CTS4 – Frequently Asked Questions
1) What is the Blackburn CTS4 splice used for?
The CTS4 is a copper compression splice for joining two conductors end to end in a distribution run. It is a two-conductor splice, crimped with a compression tool rather than bolted, and the body measures 2-3/4 inches.
2) Does the Blackburn CTS4 come insulated, or do I have to cover it myself?
It ships bare. Insulation material is listed as none, so the splice is uninsulated copper and you finish it with tape, heat shrink, or a cold shrink sleeve appropriate to the circuit voltage.
3) Is the Blackburn CTS4 splice rated to any connector standard for utility work?
Yes, the CTS4 is built to ANSI C119.4, the standard covering connectors for use between aluminum and copper conductors in underground and aboveground distribution. That is the spec most utility and municipal jobs call out on the drawing.
4) Can I install the Blackburn CTS4 with a bolt wrench or a mechanical set screw?
No. It is a compression connector only, so it needs a hydraulic or battery crimp tool with the correct die. If you want a connection you can install and re-open with hand tools, you need a mechanical set screw or bolted splice instead, not this one.
5) Is the Blackburn CTS4 made in the USA for a Buy American job?
Country of origin on the CTS4 is the United States, which is what most federally funded and municipal procurement packages want documented.
6) What part number do I order for the Blackburn 2-3/4 inch copper distribution splice?
Order Blackburn CTS4. That is the manufacturer part number for the 2-3/4 inch copper tension distribution splice.
7) Is the Blackburn CTS4 sold as a single piece or in a bag?
Each. The CTS4 is sold individually, so order one per splice point plus spares for the crew.
