5 important things when buying battery clamps

Constant contact problems?

Are you constantly dealing with corroded, damp and dirty electrical connections? We have the solution!

Sometimes the really good solutions are surprisingly simple. Such as our patented cable lug insulation - Lugsulation. Instead of simply covering contacts with a cap or rubber pipe, Lugsulation completely insulates the electrical contact. This makes moisture, acid and corrosion as well as leakage currents a thing of the past. This prevents short circuits and also eliminates contacts that can be accidentally created during installation.

Lugsulation is puncture-proof up to 10 kV and available with various protection classes. It is also free from PVC, which can be harmful to your health in the event of fire or cause major damage to property.
