Rod holder/rod clamp specification for grouper and 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 spinning tackle for grouper fishing. Popular for bottom fishing, etc. Well-received for harbor grouper fishing and live bait fishing. Rods and clamps are not included. Only the 7th photo is included. Please check the dimensions of the clamp base from the 9th photo. Made of all stainless steel with 6mm flat bar specification. This is a new product, but 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, M12 compatible, single-point fixing possible, and even more secure with two-point fixing (one side is a long hole). We recommend using hexagon socket head bolts for the fixing bolts (the ones you turn 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 use with longtooth grouper (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. Furthermore, it is equipped with a rubber spring for load absorption! I don't know about classes over 20kg! LOL Perhaps it is assumed to be 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 is not necessarily rustproof. 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.
