This lisitng is for one dozen 11/32nd Bohning Classic nocks.  The classic nock has a nock locator for easy alignment when fletching and for nocking the arrow while shooting.  These nocks are suitable for wooden arrows of a 11/32 size diameter.  The nock groove is quite forgiving so is ideally suited for a 14 strand Dacron B50 string.  If you are usiing Fast Flight or BCY 8125 then we recommend double serving the string for these nocks or building up the nocking point with something like dental floss or string serving material for a good fit.  To test the fit of your nocks on your string you should be able to hold the bow face down with the arrow nocked on the string so that it doesn't fall off (if it does then the nock is too loose), you should then be able to remove the arrow from the string by lightly tapping the bow string while the arrow is in a face down position.  The arrow should fall off without having to apply too much force (if it doesn;t then the nock is too tight).
