66-Clip Blocks

M Block: 25-pair (66M1-25)

25-pair M block contains 50 rows, each with a single clip having four slots. Incoming cable pairs ("tip" and "ring") are connected by terminating "tip" on the leftmost slot of one row and "ring" on the leftmost slot of the next lower row. The three remaining slots in each clip are available for cross-connects. Dimensions: 10"H x 3.31"W x 1.19"D.

Split M Block: 50-pair (66M1-50)

Split M block, like the 25-pair M block, contains 50 rows of clips, but instead of one 4-slot clip, each row contains two separate 2-slot clips. By terminating 25 incoming pairs on the slots of the left-hand clips and an additional 25 pairs on the slots of the right-hand clips, 50 cross-connects can be made. To make or eliminate connections even faster, bridging clips may be used to connect the two  adjacent sets of clips together. Dimensions: 10"H x 3.31"W x 1.19"D.

M Block with Female Connector

50-pair M block with prewired, pretested 25-pair female connector on left side fanning strip to speed connection of incoming pairs.

M Block with Female and Male Connectors

50-pair M block with prewired, pretested 25-pair female connector on left and male connector on right for fastest installation. Simply plug in connectors and insert bridging clips to complete the connections.

Connectorized Demarc Block

Designed for use at the demarcation point, this 50-pair M block includes mounting bracket and snap-on orange cover with designation strip. Prewired, pretested 25-pair female connector mounted on right side speeds connection of customer premise equipment to the network interface.

Bridging Clips (SA-1)

Bridging clips press onto the two center slots in any row of a Split M block. If outside cable pairs are terminated on the left-hand clips and station equipment wire is terminated on the right-hand clips, then connections can quickly be made or eliminated by simply inserting or removing the bridging clips. They can also be used on other products that use 66 clips. Made of phosphor bronze alloy, these clips provide long-term conductivity in even the most hostile environments. Because of their durability, they can easily be removed and reused for rewiring.
