Hey Michael, hey all,
on the etsy item page, it says it creates a track of 2 inches (50.8 mm) width at the inside, but there is only a drag chain of 40 mm width included (17 x 40 mm). I assume that a 50 mm wide drag chain would also fit, is that right?
2 inches / 50 mm is much more than the much too small Onefinity drag chain (see drag chain width calculation for your individual needs).
Thanks for providing the link!
