I have two stainless steel splitters. These were used on my Carter 35, 35' sloop. One was used on the backstay and one was used on the jumper-stay. These were fabricated in 1985 in England. The holes in each splitter are sized for 1/2" pins. The photos show the remaining dimensions. These items include the hardware shown in the photos.
These splitters are $25US each plus shipping. These items are located in Corpus Christi, Texas.
