The Blazer Jig's unique clamp system provides more adhesion force than standard fletching jigs. It is available in two configurations. The Blazer Straight Jig includes a gray clamp that does a straight fletch on vanes up to 2.125" (54mm) long. It is designed for smaller arrows with an OD of .25" (6.3mm) or less, and is capable of 3 or 4 fletch (4 at 90° or at 60° x 120°). The nock receiver on the Blazer Jig accommodates standard nocks.
