Pitons supporter for 16mm shafts. Inner diameter is 19mm, plate thickness is 1.5mm. Prevents pitons from falling over when fishing for Ishidai (striped beakfish) and Kue (longtooth grouper). I made these for an acquaintance and they were well-received, so I made more. I use them myself and they're excellent! I used to use two-legged supports, but this is easier now! Perfect for 16mm shafts. I've tested them many times and made them the easiest length for attaching and detaching. The item for sale is only the item in the second photo. The shaft is not included. Insert the supporter onto the piton rod and hammer it into the gap/hole. Determine the height of the supporter, lock the knob, and tighten the M10 bolt to complete. It's very easy and quick to set up, and the reinforcement is outstanding! Avoids piton tipping over due to unexpected large fish. Weight is 150g, light and compact! Affordable price. There may be scratches on the material and small scratches from manufacturing. Due to being handmade, there may be slight distortions, etc., that do not affect use. Everything except the knob is all stainless steel. It will be shipped in the condition shown in the second photo, so please refer to the ninth photo to assemble the knob. Tighten the red cap firmly with a coin or similar. I am also selling on other sites, so I will delete this listing if a purchase is made there. The price is set as low as possible, so please refrain from price negotiations.
