Gold strapnut for use with endpin jacks. Please note that this is the strapnut only, and make sure you select the right version. This metric thread version can be used with LR Baggs' Italian-made strapjacks. It also fits most Fishman and most Far Eastern strapjacks.
The metric strapnut won't fit on a US fit strapjack; a US fit one will go on to a metric one, but will be sloppy.
