Black Box CAT5e Hard Wire Coupler connecting block

Feature 110-style punchdown blocks. Use with solid wire cables. Here's the answer to every data cabler's worst nightmare-cables that aren't quite long enough. Instead of ripping out an entire cable run, you can simply punch down a new length for a high-quality, sturdy connection. Choose from two couplers: one for unshielded cable and one for shielded cable.
