“It’s a really easy solution for a very difficult
problem,” says creator of the Wyli and owner of Wyli Tension Disc, Erik Gerssen. Having worked with the construction of industrial buildings for many years, Gerssen noticed that it was not always easy to find a simple
and fast solution to tightening up wind bracings in, for example, factory halls. “There were well-known products such as turnbuckles and tension rods that would do the job of tightening up wind bracings. But turnbuckles are not very strong and tension rods are known to be very expensive.”
