For hooks #28 to 4/0 Traveler 2000 Series - US Reg 2535148 Renzetti Inc introduced the Traveler Series Vise to the world in 1988. It offered the True Rotary feature Renzetti Inc is known for, as well as portability, unquestionable hook holding power, and an affordable price. Since then it has become the most popular vise in the world. In our constant quest for perfection, the Traveler Series Vises have undergone some major improvements like the cam jaws for faster tying, the incorporation of a larger base, and a longer base stem. What we did not change is its distinctive Bent Shaft, a Trademark of Renzetti Vises Reg 2535148, praised for its unmatched strong hook holding power and versatility. The Traveler 2000 is not anodized and to fully utilize its custom features, it must be ordered for a right-handed or left-handed tyer. Traveler 2200 & 2300 Series It&';s difficult to improve on a classic, but the most visible change is the anodizing on all aluminum parts, which ensures a longer-lasting finish to the vise. A 7" stem on the base adds more comfort for the tyer, a larger base adds more balance and a polyurethane O-ring on the jaws adds longer wear to your tying experience. To utilize the custom features of this vise, order it for a right-handed or left-handed tyer.
