NavePoint 8U, 12U, 22U Height Expandable 2 Post Wall Mount Rack - Adjustable Server Rack for 19 Inch Standard IT Equipment - Wall Mount Rack 17.5" Deep, Black

I needed something I could place in my sump pump closet above the drain pipe and this just worked perfectly. i wasn't sure how it worked with the expansion, so I didn't get the full height out of the unit. Was hoping I could adjust in U's instead of the whole expansion size. Nonetheless, it fits and holds my equipment perfectly.

Installed easily by myself on wall.
