System Comparison

SYSTEM 28
Details
- Borehole Ø 28 mm
- Material thickness approx. 24,5 – 27 mm
- Boreholes on the surface in diagonal grid or 100×100 mm grid
- Boreholes with radius 3 mm
- Height of table side 200 mm / 300 mm
- Recommended load up to 6000 kg*
max. 2000 kg per leg basic equipment
max. 3000 kg per leg basic equipment PLUS
Our largest system is ideal for light to heavy workpieces due to its high resilience and rigidity. The solid clamping devices also keep large components in shape and prevent distortion when welding the individual assemblies.

SYSTEM 22
Details
- Borehole Ø 22 mm
- Material thickness approx. 17 – 19 mm
- Boreholes on the surface in diagonal grid or 100×100 mm grid
- Boreholes with radius 2,5 mm
- Height of table side 150 mm / 250 mm
- Recommended load up to 3000 kg*
max. 1500 kg per leg basic equipment
We recommend our System 22 for fine details to medium heavy fabrications. For everyone who cannot decide.

SYSTEM 16
Details
- Borehole Ø 16 mm
- Material thickness approx. 11,5 – 13 mm
- Boreholes on the surface 50×50 mm grid
- Boreholes with radius 2 mm
- Height of table side 100 mm / 150 mm
- Recommended load up to 2000 kg*
max. 1000 kg per leg basic equipment
Our System 16 is the right decision for fine details fabrications, such as railings or frame constructions.
