Does the job

Comes with two washers.
They are domed which helps it grip.

Just what I needed

I bought the lap machine knob for my old Gryphon Lapidary Workshop flat lap that was missing the knob. It works like a charm! I also really appreciated how helpful customer support has been answering all my lapidary questions and helping me find the right products.
I'm unsure why the knob comes with two rubber washers though. Is it just a spare?

Hi Ryan - We are glad to hear that our lap knob works on your Gryphon machine. We include two rubber washers just in case you need an extra tight fit. If one washer works for you, keep the second as a spare.
