Thank you for viewing! This is a set of a spool and a long shaft that allows for speedy line replacement and salt removal. By setting it on your drill and rewinding it onto the salt removal spool, you can remove salt from the entire spool. The salt removal spool has holes, allowing for more effective salt removal. In addition, a spring is installed inside the salt removal spool. When you strongly pinch the spool from both ends by hand, the shaft width of the spool expands, creating tension. By repeatedly expanding and contracting the shaft width while running tap water, you can achieve even more thorough salt removal. One side of the long shaft is hexagonal, and by using an electric screwdriver, you can wind the line quickly and easily. ●Specifications● ■Salt Removal Spool Size: 125mm x 125mm x 145mm Weight: Approximately 265g ■Shaft Length: 280mm Diameter: 8mm Hexagonal Tip: M6 ●Notes● ・Electric screwdriver and line are not included. ・Discounts are not available.
