Thank you for viewing! This is a set of two latest-model, main-shaft-attached rocket cages. Sizes: Rocket Cage: M Main Shaft: 1.8mm x approx. 190mm By making the lower part of the latest-style main shaft screw-on (see image 4), you can easily replace the weight and cage. Through-hole weights can be attached inside or outside the cage. * If the main shaft doesn't fit through the hole in the weight, please enlarge the hole with a 2mm drill bit (available at 100-yen stores). Also, a hook attachment fitting is included so you can use weights other than through-hole weights (see image 3). When using through-hole weights, remove the hook attachment fitting. The rocket cage allows you to adjust the amount of bait. This product can also attach a stainless steel cage with a lid. Since there is no hook at the bottom of the vertical shaft, tangling of the rig is reduced (when using through-hole weights). * This product does not include weights. How about it for cage fishing from the rocky shore or breakwater? I use it for long-distance cage fishing for blue-backed fish. * Please comment if you have any questions. * This is a handmade product by an amateur, so please purchase only if you understand. #RocketCage #BalanceCage #LongDistanceCage #RockFishing #BreakwaterFishing #CageFishing #FishingRig #SlidingBalance #FishingBalance - Type: Chum Cage - Material: Plastic - Color: Transparent - Size: Approx. 15cm - Features: With hook Thank you for viewing!
