All the ones we have in stock use the Torx head screws top & bottom and
are not cracked. Of course, they are in still in stock, so they have not
been exposed to weather or temp cycles.

I just checked all the new undeployed stock I have on the shelf at the
office. 13 total, 6 from WAV, 7 from Streakwave, all received around
the end of August. I saw no cracks and FWIW only Torx head screws.
These have all been at room temperature, not exposed to hot/cold
cycles or vibration like riding around in the truck.

The ones I know of, the guys brought them back in after going to an
install, taking them out of the box and finding the cracks.
I usually touch every new SM, but we were going through them pretty
fast back in the summer switching customers out. These all came loaded
with 13.2.1, so I told them to just set the region and click the
default frequencies button and have at it. I can't say for sure if
they were truly bad out of the box. So I'm not going to say "hey
Cambium, WTF" if it was one of the guys being careless. But I got them
from three different guys and they all said they pulled them out of
the box that way. I found this last one on the shelf in one of their
trucks while looking for the damn walkie-talkies they don't bring back
in to put on the charger! That drives me nuts.

Are these only showing up after some time in the field, or do you see
this on undeployed units you pull off the shelf?
I am not looking forward to the idea of going out and inspecting all
the 3.65 SMs in the field, although it sounds like you have more of
them than me.
Time to buy a quadcopter? Webcam on a long stick?

The screw thing is the two that fastens the bottom port/ID label
thing on. The larger screw heads would stick up a bit too far and not
allow the cap to be locked. I've fixed many by tightening those a bit
as suggested and it works fine. Probably had 80-90 of those so far.
This one has one of the normal torx screws and one phillips head
holding the bottom on. Got maybe 10-20 like that. And the phillips
head screw isn't on the side with the cracks in the front cover of
this one. So... I don't have a clue how this is happening.

Wasn’t there a thread about screw heads sticking up and Cambium
saying to just torque them down? Could the factory have used the
wrong screws?

Somehow we ended up with a small handful of these. Always in that
spot and I have no idea why. They're obviously going to leak. I'm
betting Cambium won't cover them under warranty either (and I don't
blame them), but we did end up with one or two that came this way
new out of the box. This one I think one of the guys stupidly tossed
on the shelf in the truck. They're not worth sending in for repair.
I'll just wait until one is murdered beyond repair by lightning and
steal the cover. But I thought I'd ask this anyway... can we get
these covers anywhere so I can just fix them myself?
