Q: What is the difference between a 66 and 110 block?

A: While both are punchdown blocks can run telecommunications wiring 110 blocks are the newer version and are able to run telecom and data communications reliably. 110 blocks enable the twist of the cable to be maintained up to the termination point.

Q: What does pre-wired mean?

A: Pre-wired 66 blocks are internally wired and allow you to only have to punch down the incoming service. A telco cable or line cord is then plugged in for the premise wiring. This saves time during installation.

Q: What type of wire should be used?

A: The wire type used should be 22-26 AWG solid copper wiring.

Q: What kind of tool is used to punch down the wire?

A: An impact punch-down tool is highly recommended. This will punch the wire down and cut it in one motion saving time and gives a much cleaner install.
