Are the 10' precut rolls cut square so that multiple rolls can be installed seamlessly?

Our 1/2" Pre-Cut Mega Rubber Rolls are not trued, so they will not be exactly 4' wide and won't be 10' long as well. They can be cut to fit so that multiple mats can be installed next to each other as they will be virtually the same size just like our standard rubber rolls. We do leave an extra few inches at the end of each roll because no room is perfectly straight. This ensures that you can install your flooring to fit the space you are trying to fill.
