ZTE Wall mount

Wall mount for ZTE routers with knobs for mounting ZTE GPON ONT units (in my case it was ZXHN F601)

The original model was made H3640 for but it works for my H3600P. 

It may also work on other models featuring to long stipes-holes on the back of the device, like these:

I have found out that newer models use these types of holes. Older models have different mounting holes.

In some regions the devices might have a DIGI or other “brand name" label on them.
