Reddit mentions of Leviton 47615-NYL Push-Lock Pins for Structured Media Centers, Bag Of 20

The modem and router are held in by one of these:

Leviton 47612-UBK Universal Shelf

These have a standoff/negative space behind them so thats where all the power wires for everything are coiled up. Once you have one of these, you can get some 3/4"x1/16" aluminum bar from Lowes/HD and cut it to length and transfer the spacing for the pushpin holes to it from one of the Leviton shelfs. Drill those out and put some of these in there:

I painted mine with white appliance enamel. You can put those wherever you need them and use some velcro cable wraps around both sides of them to secure the devices to the enclosure.

It looks like Leviton actually makes a version of these now:

...but for $23/pr you can do better/stronger if you go the thin aluminum bar route and make about 6/8 of them for about $10, including the Leviton push lock pins.

I'm not sure what we're asking here.

You've got a "structured media panel" in the wall. I'm not sure what brand, but not Leviton, which is what I mostly install.

The holes in the back are for mounting stuff inside the box. A lot of times I'll just use zip ties, but a lot of components and blocks are designed to fit that spacing. Take a look at a coax block:

Or here's a network switch that can mount into those holes:

See the black prongs on the back? They snap into those holes in your panel.

In fact, you can buy just the plugs if you want and hang anything on them:

I have the same cabinet. The backing has little holes in it. You use these little pushpin snap connectors. Each component has a little hole that lines up with the backing holes so you can pin them in.

It uses those little black stand off things. You insert it into the hole and then push down on the top and it locks down. If you by Leviton switches/patch panels, they usually come included with it (look at the Leviton switch I linked above, it's attached to the four ends of the switch). And for mounting gear in it that's not made by Leviton, they have special brackets that just hold a device in place and mount using Velcro straps. But save money and just mount it yourself using double sided tape/velcro straps etc...

Here is their universal bracket to mount non-leviton hardware:

Hi I have a similar network enclosure box - how do you mount the cable box/switches/router?

I tried using screws through the holes but they weren’t secure enough to mount things and one even went thru the single layer of drywall I have on the other side.

I googled some Leviton push-pin locks for their brand of enclosures, and people using L brackets
