Abstract: A versatile animal-immobilizing chute or cage structure is an integral vise framework having open ends and no bottom, comprised as a fixed side wall unitary with a top wall, and a movable opposed side wall, the movable wall comprising five or six longitudinally spaced upright frame columns each slidable along a top wall member toward or away from a corresponding fixed member by individual linear hydraulic motors, to grip the sides of an animal body between the vise walls. The vise inner surfaces are comprised of cushion bodies having friction casings fitted over inflatable bags or bladders that may be distended by pneumatic pressure, mounted on swivelling plates to conform to animal surfaces engaged.
