Schweiss Doors’ hydraulic doors feature wrap-around hinges with grease zerks on every hinge. Hinges may be greased from the underside of the doorframe without having to remove the top rubber weatherseal. The wrap-around hinge brackets connect directly to the vertical push tubes for strength. Doorframes feature double push tubes, which evenly distribute forces from the hydraulic cylinders to the doorframe and wraparound hinges.
