Every move is precise.

The handles are designed so intuitively that you automatically grip them correctly. Thanks to their ergonomic shape, the handles are easy and safe to use, even when you need to act quickly.

Flood level determined quickly and easily

This gives you, as a homeowner or tenant, the opportunity to react early and inform the relevant contacts or the insurance company in order to avoid damage as much as possible.
