Rod holder/rod clamp specification for grouper and ara (longtooth grouper), short type, for sale. (Rod holder only) Rod clamp φ8mm specification. (Shaft is 8.1mm) The clamp part and the main body are not integrated. They are tightened together with bolts. Suitable for ishidai rod clamps, lure rods, and grouper fishing with spinning tackle. Popular for the trendy "bukkomi" fishing, etc. Well-received for harbor grouper fishing and live bait fishing. Rods and clamps are not included. Only the 9th photo is included. Please check the dimensions of the clamp base from the 10th photo. Made of all stainless steel with 6mm flat bar specification. Although this is a new product, there may be minor scratches due to the manufacturing process. Please judge from the photos. The final finish is polished to a shine. Fixing hole φ12, compatible with M12, can be fixed with one point, and even more secure with two points (one is a long hole). Hex socket head bolts are recommended for the fixing bolts. (The type that is turned with a hex wrench) (Normal bolts are also acceptable) 3 patterns of angle adjustment are possible. Above all, it is compact, with a total length of 35cm and a weight of about 1200 grams, lightweight and can be stored in a bag, which is very convenient! Perfect for two rods! Also ideal for ara (grouper) rods and ishidai rods. I have been using the same product for 10 years, and there was no deformation of the flat bar even with over 10kg fish. Furthermore, it is equipped with a rubber spring for load absorption! I don't know about fish over 20kg! LOL Perhaps it is intended for up to 20kg. The rubber plate on the receiving part is attached with double-sided tape. Please reapply when it peels off due to use. I will accept questions, but I make each part carefully, and it takes a considerable amount of time, so I would appreciate it if you could refrain from lowering the price. Thank you. Stainless steel is a rust-resistant material, but it does not necessarily mean it will not rust. The next production is undecided, but I plan to list it. Please check the product carefully after purchase. In that case, please contact me with a message before evaluation. I am also selling on other sites, so I will delete this listing if a purchase is made there.
