A handler pushes the crowd gate past the handler gate

A handler pushes the crowd gate past the handler gate, the steps out onto the catwalk along the outside of the crowd pen. The ratchet latch on the crowd gate catches on the metal strips welded to the crowding pen wall. Ratchet cogs 12-inches (304cm) apart. Cogs: 3/8-inch (9.5) thick, 2-inches (50cm) wide, and 12-inches (304cm) apart. See details for ratchet latch on page 173 of the Humane Livestock Handling book.
