MokerLink Adjustable Rack Mount Ear for 17.3 inch Switches, Compatible for HP/HPE/ProCurve/Aruba/OfficeConnect Network Switch...

Good

This was a perfect fit for the Cisco SG-200

Used on an older managed switch. It provides a lot of wiggle room to make it work for your setup.

Unfortunately, this didn't work for what I was hoping to use it for (a Cisco CBS350 switch for which the relevant parts seem to be unavailable at any price). Unfortunately, there were a number of critical dimensions not posted that I needed, so I ended up ordering it and hoping for the best. With these plates, you'd end up drilling the plate slightly for both screws unless you want to mount it at an angle, and it would be set back a lot (similar to the factory mounting bracket. But it could be used. The reason for my bad rating is that the screws that come with this are worthless. They *barely* stick through the metal plate, sticking out only about 2mm beyond the other side, which is grossly inadequate, and would strip out very easily. The recommended minimum amount of thread contact is 1.5 x the screw diameter. So for an M4 screw, you should have at least 6mm of screw sticking into the machine, not 2mm. In fact, the 4mm screws didn't even start to grip the threads on my Cisco switch, and that's probably true for almost anything you could screw them into. But even if they did, you could strip out 2mm of threads in one second flat. I really can't imagine what they were thinking when they made the screws so short. Other info: Before I ordered this, I asked a question about the dimensions, and got no answers. Here are the missing critical dimensions that I needed, but were unavailable, just in case it helps somebody else in the future: 1. Maximum distance between screws: The distance from the outermost point of one slot's curve to the outermost point on the other slot's curve is about 75 mm. Subtract the screw diameter from that number to get the minimum distance from hole to hole. So if you're using an M4 screw, it would be about 71mm. 2. Minimum distance between screws: The distance from the innermost point to the innermost point is about 6 mm. Add the screw diameter to that number to get the minimum distance from hole to hole. So for an M4 screw, the minimum distance would be about 10mm.

A tad pricey, but gets the job done well. Includes cage nuts and all.
