Abstract

A cable carrier chain made of pivotally connected pairs of spaced apart, parallel sidebars has crosslinks spanning the pairs of sidebars which are engaged in notches in the edges of the sidebars. The crosslinks are placed in the notches and are longitudinally slid to an engaged position where flanges of the crosslinks are received in undercuts in the notches to secure the crosslinks to the sidebars against vertical relative movement. In the engaged position, bars, bosses or tenons of the sidebars which have laterally facing surfaces are engaged by slots in the crosslinks to prevent lateral movement of the crosslinks relative to the sidebars. A key or a tab is provided to secure the longitudinal position of the crosslinks relative to the corresponding sidebars to prevent retrograde movement of the crosslinks from the engaged position.
