Abstract
An improved open end construction for jacks which provides for tabs which extend at right angles to the side surfaces of the channel members so as to allow pivot pins to be received in the open ends after which the tabs are bent so that they lie in the plane of the side surfaces of the channel members so as to lock the pivot pin in the ends of the channel assembly. Also, partial flanges can be formed about the openings in the ends of the channel members so as to provide bearing surfaces for the pivot pins.
