Fin case feedback - cracked screw posts, alternate DIN mount idea

I received my Fin case a couple of weeks ago and excitedly assembled it using the included screws (the shorter ones, since I left out the terminal block ring). Today I took the case apart to flash a different OS on, and I noticed that all 3 screw posts on the lid had cracked (image attached). Besides that, the case is great - all of the port cutouts line up perfectly, and the power connector jumper is a nice touch.

I would also like to suggest an alternate DIN rail mounting point on the side of the case, possibly the HAT connector side, to save space on the rail - industrial Ethernet switch for inspiration.


Glad you’re having a good experience so far. I can’t see the extent of the crack from the picture, does it extend all the way to the base? Anyway, if it’s compromising the screw attachment, please send us an email to with the picture so we can send you a replacement. We would like to investigate the cause and make sure it’s a one time issue.

Thanks a lot for your feedback on the DIN rail mounting position, we’ll keep that in mind for the next revision. The current configuration prioritized easy access to all the connectors on the balenaFin.

I’d like to second the request for the DIN mount on the slim side of the case. We are looking at creating our own version of the case for specifically that purpose. If you guys are making one, we’d prefer to have it from you.

Also we’d like to expose the 24v power without the need for the riser board and other I/O ports. Essentially remove the barrel connector and use a block, similar to that ethernet switch referenced in’s post.

Hi James,

Thanks for the feedback! If I correctly understood your last requirement, the standard version of the case exposes the 6-24V barrel without the need for the riser board (or any other ports).

The barrel jack on the case is connected to the input power of the balenaFin through the cable highlighted here.


You can buy the “Non-Ring version” from our store.


I agree with and @jgentes on the fact that having the DIN mount on the slim side of the case could be a better choice in some situations. A lot of other DIN-rail mounting tools seem to use a vertical design, such as
