This type of coffee mug holder is ideal for organizing and saving space.
Unlike a coffee mug tree, it is not a table top stand. A hanging rack usually mounts under a cabinet or inside a cabinet on the underside of a shelf.
This type of hanging rack typically has one or more metal wires that extend over the top of a shelf.
The mugs hang from metal loops or hooks on the underside of the shelf.
Different racks are spaced differently, some for larger mugs, others for smaller tea cups.
Items on the shelf above must usually be organized to fit around the wires that support the rack.
This type of coffee mug hanger actually attaches to the underside of the shelf or cabinet.
It is usually a pretty simple mount, using screws to secure it.
The one in the photo is a plastic rack for holding lighter, smaller coffee cups.
A nice thing about this style is that it slides out, allowing easier access to the mugs without having to reach underneath the cabinet.
