Contact Sponsorbolt directly

Sponsorbolt is a relatively new brand, thus we really like to talk to you. It is only then we can learn all about your needs and desires. If we haven't got the right clamp for you we can develop it for you. 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 all along the fence poles. And BetaMount was developed after Elia Asset NV - the powerplant network of Belgium - contacted us for a swift and versatile clamp mounting all of her warning signs on to multiple fences. 

When your demands and desires meet the market of other potentail Sponsorbolt clients, then everything is possible.

This is how reach us directly
