The Dell 575-BBIV (also known as MK15) is a dedicated mounting kit designed to help you organize your workspace by relocating your docking station. This black bracket is specifically compatible with the Dell Dock WD15 and Dell Thunderbolt Dock TB15, allowing these devices to slide securely into place to clear up valuable desk area. Because it supports VESA standards, you can install the kit behind most Dell UltraSharp and P-series monitors, though it also works well when attached to walls, under desks, or on flat surfaces. The package includes the mounting bracket and two screws, providing everything you need to tuck your hardware away and maintain a cleaner, more professional environment.
