Extreme Gear TIE ON A STRING NOCKING POINT Material 48" Per Pack Enough Material For 4+ Nocking Points ( SEE ITEM TITLE FOR COLOR ) Great For Loop Shooters ! For years the brass type nock has been standard equipment. And why not? It works well. But a tied-on nock works even better. It's less likely to slip or damage your serving, is easier to adjust, and even allows your bow to shoot a few feet-per-second faster because of it weighs less than a brass nock. If you tie a nock on properly it will last through at least a year of regular shooting. I've used this type of nocks on my hunting and 3-D bows for over two years and they're still working perfectly.
