The present invention has to do with longitudinally adjustable pusher lugs for conveyors, the lugs being adapted for use as original equipment or as replacements for presently conventional, adjustable pusher lugs which cannot be depended upon to hold their adjustments for any extended period. The present lug includes a base or mounting member adapted for fixed attachment to the conveyor but never intended to engage a work piece, and a pusher member clamped thereto with capacity for longitudinal adjustment relative to the mounting member. Both members are formed with numerous longitudinally extending ridges of like trapezoidal cross-section, the sloping sides of adjacent ridges forming V-shaped channels between them.
