crossbar
a short metal rod or bar fashioned to form a clamp or clip and used to hold watertight doors, manholes, or pieces of work in place. On watertight doors, it is usually a U-shaped fitting composed of two main pieces, one of which is bent to form a right angle, with a handle on one end, and the other end passing through a gland in the door and having a screw thread cut on the end to which the second piece, in the shape of a handle, is attached. The complete dog has a handle attached on each side of the door which when turned works over a wedge on the door frame and compresses a rubber gasket fitted to the door against the toe of the flange of the door frame.

On manhole and hatch covers giving access to compartments in the ship's structure, the dogs usually consist of drop-forged fittings riveted to the cover. U-shaped openings in the dogs project a sufficient distance over the edge of the cover to allow drop bolts hinged to the manhole or hatch frame to swing into the openings and be tightened by nuts.
