66 M Wiring Block 25-Pair

This 66 M wiring block provides a 25-pair termination point for voice and low-speed data circuits. It is built for technicians who need a compact, standards-compliant cross-connect in telecom rooms or equipment cabinets.

25-pair capacity with 4-pin rows

Each of the 25 rows carries four pins, giving 25 clip pairs in a single block. The layout handles standard 25-pair cables cleanly, but it does not scale beyond that count without adding another block.

CSA and cUL listed for rack mounting

The block measures 10 in deep, 1 1/4 in high and 3 3/8 in wide with no attached legs, so it fits standard distribution frames. It meets TIA-568-C.2 and UL requirements, freeing installers from separate compliance checks.

Questions about this item

Will the 66 M wiring block connect to my existing 25-pair cables?

The block has 25 pairs and 25 clips with clip pair type 1, matching standard 25-pair cable counts for direct termination.

How can I verify the block is seated correctly after mounting?

Each of the 25 rows accepts 4 pins per row; fully inserted conductors should sit flush in the IDC clips with no visible gaps.

Does the package include mounting legs or do I order them separately?

The block ships without attached legs; mounting hardware must be sourced separately.
