Tiemco TMC Twin Hackle Gauge- This gauge easily rests on the stem of the vise. It has two measuring pins; one is for standard patterns and the other one is for parachute patterns. The hackle will not slip around the tapered pins while measuring. The stem hole is a little bigger than the diameter of vise stem so that the gauge will have an angle towards the tyer and it will easily rotate out of the way while not in use. Fits onto most vise stems.
