  • Use PVC pipe or similar material instead of the spacer shown above to adjust the distance between return rollers when the plate width is greater than 83mm.
  • Return rollers for stainless steel top chain will not rotate when combined with plastic chain, and may cause uneven wear of top plate surfaces.
  • See illustration below for wide width Top Chain. Return roller installation examples4 Notice: Curved frame end sections should not be in the inner side of the guide width.
