This is six feet of absolutely beautiful, durable stainless steel fret wire, in handy pre-radiused 8-inch lengths. This fret wire is produced one of the best-known German fret wire companies and is a bright silvery 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 considered to be of medium crown width and medium crown height, but overall is close to Stewart-MacDonalds #148 "medium/medium" standard fret wire. This fret wire can be used to repair/replace frets on an existing electric or acoustic guitar, banjo or other standard-to-smaller sized stringed instrument, and it is also great for new instrument building. The dimensions are as follows: Size Specs: Crown Height: .043" (1.09mm), Crown Width: .080" (2.03mm), Tang Width .020" (.510mm). 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.
