※Please note that this is not the reel body. ■This is a stopper for the Battle Field BK90NR. (Operation has been confirmed on BK80NR as well) ■Because the Battle Field has a very smooth rotating reel, backlash often occurs when threading the line through the guide, when moving, or after putting a black sea bream into the landing net. This stopper is to prevent that. ■To use it, simply tighten the screw by hand a little firmly and slide it up and down. Up stops, down is free. ■Please refer to the photos for the installation method. ※We will send it assembled in the correct order as shown in the last photo. The center paper indicates the position of the main body. ※There are two large and one small semi-transparent nylon washers, but please sandwich the reel body with the two large washers. The rubber washer prevents loosening. ※The nylon washers sandwich the reel, so the reel body will not be scratched at all. ■The screw part is the same color as the red part on the Battle Field body, so it can be attached without looking out of place. ■I think you can tighten the screw by hand until it doesn't loosen, without using a special wrench. ※Important! If you feel it loosening during use, tighten it again constantly. ※Attention! The product is only the stopper. The reel body is not included, so please be sure not to make a mistake. ※ If you purchase now, you will receive 3 Keimura Fujitsubo as a trial, so don't miss out!!
