Linkage member for an anti-tip/interlock device

In a multi-drawer filing cabinet arrangement of vertically disposed drawers mounted on progressive telescopic two or three channel drawer slides, with an interlock mechanism, an improved connecting stub is used. Field installation, assembly, disassembly, replacement or repair of particular cabinet drawer or interlock mechanism can now be accomplished due to the arrangement and configuration of an improved connecting stub for use in an interlock mechanism without taking the file cabinet apart. The connecting stub comprises a partial pocket where the arc segment subtended by the partial pocket is more than 180 degrees and has a predetermined length, thereby allowing lateral or transverse insertion and removal of an associated vertical actuator locking vertical connecting rod without taking the whole filing cabinet apart.
