Pre-wired 110 and 66 blocks save on labor and installation time, freeing up hours you can spend on other important projects. Lightning-protected blocks are ideal for small PBX installations and are stackable for convenience.
Need a backboard or wall mount? We have those, too. We stock easy-to-install brackets in several different sizes and styles to fit your networking needs. Choose from different colors and capacities.
Cable management troughs are also a key part of keeping your wiring closet easily managed. Use the troughs between wiring blocks to sort cables, with or without stand-off legs. You can buy a complete kit or create one yourself.
While you’re at it, pick up some mushroom wire posts and spools. They’re designed to guide your cables quickly and neatly, with easy access for changes. 


Remember, spend $200 and shipping is free for qualified orders. If your order is delivered outside our home state of California, you will not be assessed sales tax, either.
