Hey guys I was wondering why some of the Lucky clamps had slits in them and mine doesn't I'm about 100% sure its so that when you tighten one of the bolts then the other one gets loose then visa versa, if you know what I mean.
They first made them like that just like the district clamp and then they started to snap when tightened to much so they got rid of re slit and now none of them have broken and they are stronger.
