Abstract: A drain assembly for a tank or containment vessel of the type having a flexible and removable interior liner. The drain assembly comprises a drain intake in fluid communication with a wall traversing portion. The drain intake is operatively deployable in proximity to the bottom of the tank and the wall traversing portion is operatively deployable through a wall of the tank. The wall traversing portion includes a conduit portion in fluid communication with the drain intake and with a location exterior to the tank. The conduit portion includes an interior stopper plate and a threaded portion.

Abstract: A quick assembly hinge for joining first and second panels. The hinge comprises a first wing portion securable to the first panel, a second wing portion securable to the second panel, a pin mounted to the first wing portion and a hook mounted to the second wing portion. The pin is generally parallel to the first panel when the first wing portion is secured thereto. When the second wing portion is secured to the second panel, the opening of the hook bowl is directed downwardly toward the bottom surface of the second panel. With the panels generally co-planar and their respective edges adjacent to one another the hook is receivable over at least a portion of the pin. As the first panel is rotated upwardly to form a generally a right angle with the second panel the pin is rotatable within the hook bowl preventing the lateral and vertical displacement of the panels.
