Hehe, first to ask [wink]. Curiosity killed the cat! [tongue]
J/K as side.
Was looking to create a poor men's square. Basically taking the rail connectors (#482107) and put a t-slot profile (400mm) perpendicular to the rail . Now the slots needs to be, according to the measurements 80mm apart. Basically needed the info to check if I could find a t-slot rail where the slots are 80 mm apart.
