## Questions & Answers

**Q: Looking for a way to mount this to a 35mm din rail. Anyone have any ideas? Thanks**
A: Comidox Set of 5 PCB Din C45 Rail Adapter Circuit Board Mounting Bracket Holder Carrier 35mm
Universal DIN Rail Mount Clip Snap in Din-Rail Mounting Brackets
Available on Amazon
I recommend the first option

**Q: Has anyone with complaints about fit tried to cut the board down the middle with a Dremel or tin snips? That has worked for me with similar products.**
A: That's a really good idea.. You could also mount this via. multiple mount holes on a board after words so it could fit any future boards.. if your worry about rigidity  : |  -  | :
