This item is used on multiple models.
Part of 40-300T Assembly on:
TRQ200 and TRQ300 reels
WARNING: The Fathom series of reels says to use the 120-113H o-ring under the spool tension cap..but this is thicker than what is on the reel and the cap will not screw down over this fatter o-ring. FOUND WORKABLE RING: Use the 120-SQLLW on the Fathom tension cap instead.
