Our Vanguard claw has a large bowl capacity, allowing milk to flow smoothly and decreasing vacuum fluctuations at the teat. Ergonomically designed clear polycarbonate means less weight, and it's easy to watch milk flow. Has shutoff on claw (this shuts off flow from both milk lines). If you would like individual milk line shutoffs, please order inline shutoffs separately. Vanguard claw takes the special inflations and shells below. You'll need one claw for every two inflations. Shipping on the Vanguard Claw is $10.00 anywhere in the Continental United States.
