CAT5E 110 Connecting Block

These Connecting Blocks, from Dynacom, work directly with the CAT5E 110 wiring block by interconnecting two different cables. One cable may be directly terminated on the wiring block and then covered and secured by a connection block. The connecting blocks have the capability of creating a higher number of possible terminations on the 110 wiring block. The IDC terminals on top the connection blocks and the terminals on the bottom of the connecting blocks allow for connectivity between the two cables. Connecting Blocks are typically found in 3-Pair, 4-Pair, or 5-Pair clips and can significantly improve the number of connections the wiring block can hold. Connecting Blocks and 110 Wiring Blocks are commonly used between patch panels and power outlet boxes.

Telco blocks are utilized to connect phone systems to data networks. There are two popular forms of telco blocks: the 66 block and the 110 block. The 66 block is quite common in modern phone systems, as they simplify connecting multiple phone lines. The 66 block is also referred to as B-blocks, M-blocks, and as split-50 blocks. We also have Cable Distribution Spools, or mushroom posts for managing your cross connect wire. It is designed for mounting onto walls or other surfaces to help support and guide your cross connect wire. Our cable distribution spools are also ideal for Cat3 cable for telephone applications.
