Gold strapnut for use with endpin jacks. Please note that this is the strapnut only, and make sure you select the right version. This version is US thread. It may be used with Switchcraft strapjacks, including K&Ks. It is different to the metric thread version used with LR Baggs' Italian-made strapjacks, 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.
