What is a 110 block?

A 110 block is a punch-down block used to connect wiring for telephone systems, data network wiring, and other low-voltage wiring applications.

The 110 block improves on the 66 block by supporting higher frequencies and using space more efficiently.

A punch-down tool is used to force solid wire into metal slots on the 110 block.
