Double Bolt (Yoke Style) Quick Opening Closures

Tube Turns Double and Single Yoke style closures are used throughout the world for applications where frequent access is required or where blind flanges are cumbersome and time consuming. They offer smooth, direct operation and even the largest unit can be opened or closed in a matter of minutes.

Typical units consist of a forged hub, hinged blanking head, split-yoke clamps, operating bolts, and self-energizing O-ring gasket. To simplify operation and save time, Yoke style closures can be equipped with operating aids, such as breakover wrenches and chain-and-sprocket drives.
