Page 2. BEFORE WE SHIP 9 checks on every self-stacking belt before it ships 1 Side plates Parallel to the belt with a small, even gap, measured with the belt pulled tight. 2 Rods Every rod straight, so the tier plates stay vertical. 3 Weld points Each weld pressed by hand; position centred, no loose points. 4 Flat-cap welds Centred, smooth and firm on every link. 5 Tier plates Vertical and in line along the full belt. 6 Rod to plate Rod tight against the tier plate, no gap. 7 Inner slot Slot width set to 5.5 mm so the rod slides freely. 8 Sprockets Direction and pitch checked by turning by hand. 9 Width Measured at five points or more against your drawing.
