Designed for LANs with 20 - 40 drops, the Bracket Master from Black Box is easy to install and very user friendly. It provides 4U of total rack space - use 2U for modular connections and 2U for your hubs. Don't worry if your hubs are different sizes. Simply adjust the Bracket Master by sliding out the sides from 10 to 15 inches. Once you attach your patch panel, making terminations couldn't be easier. Just flip the patch panel down 110 degrees. When you're done, flip it back up. If you need to power your hub, there's space at the back of the bracket just for your power strip. To keep cables organized, the Bracket Master comes with eight hook-and-loop fastener strips for bundling cable from the wall to the patch panel. For long-lasting durability, the Bracket Master is made of rugged 14-gauge steel. It holds all standard 19" wide equipment.
