Create a dedicated control position for Logitech Tap on a Heckler Mobile Fleet MK II cart. The shelf adds a purpose-specific mounting surface to the mobile fleet configuration, placing the touch controller with the cart rather than on a separate table or temporary support. Its black finish aligns with installations that require a consistent equipment presentation. Heckler Design H1054-BK fits deployments where a Mobile Fleet MK II cart carries collaboration hardware between meeting rooms, training spaces, or shared work areas. Keeping the Tap controller on the cart gives users a known location for call controls when the display system is moved. The shelf is intended for the Mobile Fleet MK II platform named in its compatibility description. This accessory differs from general AV furniture hardware by serving a specific controller-and-cart combination: Logitech Tap and Heckler Mobile Fleet MK II. Select it when the cart configuration requires a dedicated shelf for the Tap interface. It is a hardware accessory rather than a Logitech Tap controller, display, or complete mobile cart, so the existing Mobile Fleet MK II installation remains the required base platform.
