Our Modern Guitar Wall Hanger offers two of Oregon's finest woods to create a modern, secure, wall mount solution for a large variety of stringed instruments. The Oregon Black Walnut base is precisely cut and embedded with Oregon White Oak dowels, before being finished off with a clear coat to protect the natural beauty of the wood. Due to it's symmetrical shape, the mount can be adjusted to the angle that best fits your head-stock geometry. • Easy installation, and accommodates both electric and acoustic guitars (see dimensions below) • Oregon Black Walnut base diameter: 4.75". Opening between Oregon White Oak dowels: 2" (standard electric and acoustic guitar neck widths ~1.7") • Install in wood wall or stud (recommended), or in drywall (drywall anchors not included)
