I was afraid I'd lose my mounting knob down an ice hole or off my kayak and it would ruin a fishing trip. Having a backup seemed like the obvious answer. I couldn't find anywhere that had a reasonable replacement so I created one. I can make these in two different material formats to allow people to have a few backups for low cost or more durable replacements that should last much longer. Each mounting knob comes with a rubber washer as well.

Sold as a single knob.  Add on a second knob as a backup and save 10% or make it three and save 15%!

These are 3D printed knobs press fit and adhered to stainless steel bolts.
