Tear off screw
Maxi MV clamp

Maxi MV clamp with tear-off screw

Save time on site

The Maxi MV clamp makes work much easier.

Welding is no longer necessary. You don't even need a torque wrench. Any conventional wrench can be used for safe and secure installation because the screw head simply tears off at a pre-defined clamping force.

So you save time and manpower.

A further advantage: Correctly mounted clamps do not have to be marked. This facilitates documentation and prevents application errors.


Developed for industrial requirements

The Maxi MV clamp with tear-off screw is designed to meet high demands such as those to be found in industrial buildings, nuclear power plants and military applications. It fulfils international standards according to IEC 62561-1 (Lightning protection system components - LPSC).

This is how it’s done

See for yourself how simply and quickly the work can be done. No more welding means more safety for employees.

Installation comparison

The comparison of mounting with the Maxi MV clamp and the conventional mounting method reveals an amazing time advantage which is yours to be had.
