Hammer-in tip

First of all, the tip is driven into the rafter. The clamp is then quickly closed, to allow you to start right away with powerful clamping.

Broad impact surface

The broad impact surface makes it easier to drive in the clamp.

Special tilting pressure plate

With the SPZ 80 K, the special tilting pressure plate ensures problem-free clamping even when working with sloping parts. It can be tilted by up to 35°.

Sturdy hexagonal bolt

The SPZ 80 K's tough hexagonal bolt allows powerful yet controlled tightening, with the help of a torque wrench.
