This is six feet of absolutely beautiful, durable stainless steel JUMBO fret wire, in handy pre-radiused 8-inch lengths. This fret wire is produced by the best-known German fret wire manufacturers and is a bright silvery-steel color. As an added bonus, it is some of the hardest and most durable fret wire available on the market, much more durable than standard nickel-silver fret wire, so your fret job will not only look great, but will also last much, much longer! This fret wire is called jumbo because it has one of the widest and heighest crown widths/heights available on the market, slightly larger than Stewart-MacDonald's #150 "Wide/Highest" nickel-silver wire. This fret wire can be used to repair/replace frets on an existing electric or acoustic guitar/bass or other larger stringed instruments, and it is also great for new instrument building. The dimensions are as follows: Size Specs: Crown Height: .057" (1.45mm), Crown Width: .110" (2.79mm), Tang Depth: .074" (1.88mm). A slot width of .023" is recommended for best results when installing this fret wire. Stainless Steel fret wire is more challenging to work with, and is recommended for people experienced with standard fret-work.
