Use up empty space and store you mugs in a convenient location with the Under the Shelf Mug Holder from Spectrum Diversified. The versatile teacup and coffee mug holder can be installed two different ways: mount it under the cabinet for easy access or slide it over a shelf to avoid installation. If you choose to slide the rack over shelves, ensure cabinet doors do not touch shelves when closed before purchase. If they do, sliding the mug rack over the shelf will inhibit proper closing. Coffee cup holder is easily mounted; simply place the mug rack wherever you want it, then insert the screws into the looped grooves built into the upper arm of the kitchen organizer. Sturdy steel upholds the weight of mugs easily. Thick-gauge wire provides rigid support for a variety of sizes of tea or coffee cups. Durable welds hold the piece together to hold as much weight as possible, making the mug rack the perfect coffee bar accessory. Modern mug rack holds up to 10 teacups or espresso cups. Mugs larger than 10 ounces may need to be staggered to fit. 1.5" between each hook. To install on cabinet shelves, simple slide the upper arm over the intended shelf. To mount under a cabinet, position the rack in the preferred mounting area. Tighten the screws in the looped grooves of the top arm of the rack. Mounting hardware included; alternative mounting systems may be required based on cabinet thickness. Made of sturdy steel.
