ALLEN CARBON ARROW NOCKS
Allen’s snap-on nocks make shooting easier: the friction fit design allows you to shoot an arrow for tuning purposes without glue. The string end of the nock is designed to grip the string without gripping so tightly that it would reduce arrow speed, like other nocks. Fits Allen, Carbon Express, Gold Tip, and other arrows with 9/32in diameter shaft. Friction fit can be used without glue.
