Bridging clips are sometimes used on split 50-pair blocks in place of jumpers. These industry-standard blocks are used in equipment rooms to connect voice and data network wiring to customer premises equipment. They are also used in remote and intermediate wiring closets throughout larger installations as common connecting points for nearby equipment. Constructed of high-impact, fire-retardant molded thermoplastic, Leviton connecting blocks utilize phosphor bronze quick-connect insulation displacement 66-clips for ease of installation, and proven mechanical and electrical reliability.

25 Pair 66 Block

Securely mount the 89D standoff bracket to a wall or plywood using two screws. If you are using a 25-pair block, remember that all four of the silver clips are connected. When a wire is punched down on one of them, the remaining three are live and ready for cross-connecting. A split pair M block is different.

66 block silver clip



Unlike the 50 Pair block below this 25 pair block is different. When you punch down on the left most silver colored clip in a single row it will automatically be connected to the 3 remaining silver clips in that row without using a bridging clip. With a 25 pair block like the 25 pair block each row of silver colored clips are already connected. Their are 50 rows down so that would allow you to terminate 25 pairs or 50 wires, one above the other.

Pairs should be brought in from the left side for cross connection. So if you punch down the left side then you have the connection on the 3 remaining silver clips next to it.  To terminate for example the blue pair. Bring the blue-white wire in and terminate it on one silver slot at the left. Then the white-blue wire terminate it on the next lower silver slot at the left. Now you have a terminated single pair coming in on the left side.

If you are using a 50-pair block, think of each row of four as split right down the middle. Two connections on the left and two on the right. You may terminate the cross connect on the far right side. To make a cross connect live, use a bridging clip on the middle two clips. This connects the two sides and gives the cross-connect itís signal. This type of connection provides convenient quick disconnects for turning off and on signals.
