You said you converted your Makita sander to take advantage of the plug-it. Interesting. When I had my prior boom arm (which was my plan for the articulating upgrade), I had to have 2 cords - 1 plugin for Festool and the other for non-Festool. I wanted to see if I could cut the cords of the non-Festool and use a Festool connecter, but I was told not available in the USA, but you can get it in England.

I saw what I thought was the product I needed on the Klium website, and I emailed them, and the response I got was that this product would work for me, but they would not ship to the United States even if I paid very well up front in advance with whatever method they preferred. I offered to pay an extra shipping-handling fee or insurance. Whatever they wanted. Nope. Only Europe.
If you happen to have access to them and would do me a favor, I would be happy to pay you for 10 of them by PayPal along with extra above shipping for your time. I do not need 10, but I figured a couple of people here may want 1-2 and I could help them out. If that is an option, please send me a PM.
