The Vanguard Goat & Sheep Milking Claw is used when high -producing goats and sheep require more safeguards against flooding or vacuum problems. The Vanguard’s large bowl capacity allows the milk to flow through smoothly, decreases vacuum fluctuation at the teat end and protects against vacuum loss from a dropped unit. The bowl is ergonomically designed for quick and comfortable positioning of the claw under the udder. The Vanguard is made out of clear polycarbonate for light weight and ease of visual inspection.USE WITH LINER # 64587 SHELL # 64588
