A hanger bolt looks very similar to the EJOT Solar Fastening Systems JA3 & JZ3. Nonetheless, there are important differences which indicate big advantages of the EJOT Solar Fastening Systems:

  1. The EJOT Solar Fastening is a complex system of
    -special screw for wood, steel or concrete applications 
    -setscrew with drive for mounting parts 
    -special and proven sealing elements

2. The screw length will be selected to work best with each individual project.


The screw head is the preset depth (control) stop.
Due to that the optimal intrusion depth into the substructure is always constant and not changeable allowing the necessary structural calculations.

3. After installation the sealing system realizes a perfect waterproofing

The sealing system EJOT ORKAN Storm Washer + sealing washer is used since decades for roof installations with trapezoidal profiles, insulated metal panels and corrugated metal profiles– and has proven to be a very reliable system.

4. The EJOT Solar Fastening Systems are fully quality controlled and have been approved by the DIBt (German Institute of Building Technology), whose standards are among the most rigorous in the world.

The US market is currently establishing its own testing requirements for solar products. In the meantime, approval to use EJOT products can easily be obtained from local building authorities throughout the country as Alternate Materials, Design and Methods of Construction, IBC Section 104.11.  Together with our project-related initial sizings and technical data, this makes life a lot easier for specifiers and planners!
