Just make your own! These hold solid. I used them the other day with my 55 and 106 track and when I picked them up, it didn't flex at the joint at all.
I gather that interested parties will have to visit your website to learn of the release of this new product since it will be in direct competition with the rail connectors that Festool sells. Understandable position for Festool, but kind of a shame too. In any event, congratulations on all your products! [thumbs up]
