[Handling and Installation Notes] The basic design does not use the original rubber packing. Although it is possible to install a rubber packing, be careful not to overtighten, as this can lead to deformation or damage to the rubber packing and reel. If you are concerned about salt corrosion or waterproof performance, applying a small amount of grease to the threaded portion before installation will help improve waterproofness and reduce salt corrosion.
