Got the metric thinking indonesia uses the metric system right? Well, they don't fit. Well one didn't. Maybe I will try a different one. I paid for 5 though, they should all work. I didn't pay for contingencies. Just another reason why the standard system is superior. Although, they have it wrong on the site. The unit of measure for knobs on levers and switches is the Gnuick. It is about 1/4 of an inch. I was looking for a half Gnuick knob and the search results were revolting. Maybe we should just go to the metric system in America. Gnuick it.
