Why steel tape does not exceed 10 meters?
You think about a problem. It's spring loaded with steel tape. It's so long. It needs a lot of springs
There are 20, 50 meters steel tape measure, but there is a rocking handle, there is no automatic retraction. In fact, automatic retraction is not easy to use, it is easy to damage the ruler
Yes, I've seen the longest one with 100 meters.
