110-block

A type of punch block used to terminate twist pair wire usually preferred over 66-blocks for data. It is easily identifiable since it is a white plastic trough with 1 row and usually hung horizontally. Used predominantly in telephone wiring, but can be used for data network and other low voltage applications, hence it will support Category 3 or Category 5 wiring.
