Contact Sponsorbolt

Sponsorbolt is a newly developed brand, thus we really like to talk to you. It is only then we can learn all about your needs and desires. In the end, that is how RoundMount was conceived. Dutch soccer club De Jonge Spartaan from the village of Middelharnis wanted a clamp that could lead their advertising boards along the fence poles, instead of that they had to mount their boards between the fence poles.
When your demands meet the market, everything is possible. So, start today with serious advertising board management, we really like to hear from you!
