About This Product
The Saddlemen black seat mounting knob offers a convenient, tool-free way to secure the rear of your seat to the fender. Featuring a 1/4"-20 thread, this knob is compatible with standard Harley-Davidson seat mounting locations. The black finish provides a stealthy look that blends in with dark paint schemes or blacked-out components. Its knurled surface ensures a positive grip for hand-tightening, ensuring the seat remains secure during operation. Saddlemen produces this hardware to provide both utility and a custom aesthetic for riders who value ease of maintenance. This mounting knob is sold individually and is a direct replacement for standard mounting bolts.
Manufacturer part number: 8909B.
