I’m using the shelf to mount (2) half-width mic preamps in a standard 2-high portable electronics enclosure. The Middle Atlantic unit is well made and well finished. It’s fine for a fixed (non-mobile) situation. It’s strong enough not to warp when used to support almost any possible equipment. However, it is heavy steel, and is overkill for my (2) 2lb preamps. For portable use, an aluminium version would be much preferable.
Even with the elaborate slot pattern punched through the shelf, none of the holes lined up with the mounting bolts on the (2) small chassis I was mounting. It was no problem drilling a few holes with a drill press to allow the chassis to be positioned properly. Middle Atlantic does supply some adhesive backed hook and loop strips to use, but if the item you’re mounting is a full rack space height, the hook and loop fastener takes up too much space to be used.
