Wire with Twister attachment
You only need one rails with the opening at the bottom to attach the Twister. Newly, GeckoTeq and Artiteq rails are suitable for this. Eventually you will only see a small button on the top of the Perlon wire or steel wire. Don't forget that a self-locking or screw hook is always needed.
The Twister has a "half turn system" which means that you only have to push it into the rail and then turn it half a turn to block it. Moving the Twister is of course also easy: turn back half a turn, move it and fasten it again with a half turn. Also optically a beautiful system.
