Korber modular sections

Has anyone tried building with these, or ordering from Korber? The parts are way cheaper than DPM sections. The Korber website does not list sizes, and their link to Building with Modulars is bad. If you’ve got any of these, would someone pull out a ruler and tell me how big they are? Thanks.

I have never ran into the building sections, but Korber made some great kits. I was able to find to Korber water tanks at a Train Show in Novi, MI and purchased both two years ago. I am in the process of building one now and I will probably let the other one go.
