These are the classic TCS trigger reel seats from Fuji, easy to install and use while still being comfortable and good looking. Available with polished silver and shiny gunmetal hoods. The 16 size will cover most smaller 60-200 size baitcasters while the larger sizes can accommodate bigger blanks meant for casting swimbaits and big glide baits. The 18 size can work very well for slow pitch jigging rods as it works with many smaller conventional reels.
