Mis-threads are going to happen, and if you are installing/uninstalling equipment on a regular basis you might essentially “lock yourself out” of certain rack elevations otherwise. They can be a pain in the ass to get in and out however. A trick is to note the two spring clips, normally one has a longer tip than the other.

The longer tip should be installed first. So if you are installing cage nuts on the right side of the cabinet, put the longer clip towards the right. That way when you install the nut, you only have to hook the shorter end, which is easier. Also, install them with the clips on the left and right side, instead of on the top and bottom.

Cage nuts can be inserted (in square holes) either with the flaps horizontal or vertical. I've seen and used both methods, but am still not sure which is best. Is there a recommended way of inserting them?

If so, why is it the best way? From my own experience, the horizontal way (on the left) seems slightly better for no other reason than making it easier to insert or pry out the cage nut in a full rack (with the units above and below being populated), for example when replacing cage nuts with a snap-in rail.

Edit: Major vendors each seem to have their own preference too: Horizontal:,, Vertical: (and ). I suspect it is far better to place them horizontally, so the flaps are in the direction of the force of gravity. I suspect if you think of it like, the flap kinda looks like a single corrugation, then you might see what I am trying to say. When push on the cardboard from the side it is far more likely to collapse, but if you push on it from the top, it is extremely sturdy.

If the metal uses was extremely weak, or the gravitational forces (weight) acting on it was very strong, it seems to me that the lower flap of the vertical orientation, might bend inward a bit resulting in a cagenut that falls out of the slot. Whereas the I suppose if your rack had any reason for some side-to-side force acting on it, you might want do it the other way. I prefer the vertical mounting on the right of your illustration. To remove them I put my thumb on top and my index finger below. I have all of my fingers except for my thumb curled back onto my hand like I'm gripping something. Push down and the nut rolls right out. If it falls it's only going to fall into my palm.

I just squeeze to close my fingers and I have it. I've found that when they are mounted horizontally that sometimes my fingers won't catch them and they go flying, never to be found again (at least until you empty or remove the whole rack). Using a screwdriver makes the 'go flying' part even worse. I've found that it's better to mount Cage Nuts vertically. I had a weird case where (during installation) the weight of the device pulled the top flap of the cage nut down, which caused the cage nut to come loose. This was mainly due to the fact that the only screws installed were the bottom row (half-way screwed in), with the weight of the device on them. Again, it's a weird situation.

Anyway, I had to pull the device out to remount the Cage Nut, so out of curiosity I mounted the Cage Nut vertically and recreated the scenario. And didn't have the same issue. So anyway, i vote for vertical.
