Got a fishing reel with a worn-out or boring handle? Upgrade it with this PATIKIL Metal Fishing Reel Handle Knob. It's an all-metal, flat-design knob that feels solid and comfortable in your hand. The inner diameter is 7mm, and it's designed to fit most S/D type fishing reels (perfect for drip reels with a 4mm grip shaft). The kit comes with everything you need: the knob itself, 2 bearings, 5 metal gaskets, 4 plastic gaskets, and a screw. Installation is straightforward – just layer the parts as shown (bearing, gaskets, knob, etc.) and tighten it up. Use the extra gaskets to adjust the gap if needed. It's lightweight, smooth, and durable, so it should last through plenty of fishing trips. A great little part to repair an old reel or just customize your favorite one. Remember to check your reel's size before ordering to make sure it fits!
