  • Connecting links are clip type for sizes up to RS16B-LM, and cotter type for sizes RS20B-LM to RS24B-LM.
  • RF06B-LM chain has flat shaped link plates.
  • Center sink riveting is applied for RS08B-LM-1 to RS16B-LM-1. Double stake riveting is applied to all other sizes including multi-strand chain.
  • When a single pitch offset link is used, please calculate a 35% reduction of the fatigue strength.
  • Also available in Neptune™ specification.
