My experience with the sizing devices has been that there is NO tolerance. They are as close to 28 x 38 x 60 as you will see.

If your robot is right at the limits then be assured that it will NOT fit. Your robot is not perfectly square, some of the sides are not perfect angles. A bolt head sticking out will keep it out of the sizing box.

We spent practice day on our rookie year cutting our robot up with a sawzall and ramming it into walls getting it small enough and bent straight enough to fit into the box. Not much fun.

We make sure every measurement is a minimum of 1/2" inside the limits. Fix it now or fix it at your regional, your choice. It's much easier to fix things at your shop.
