Has anyone used one of these or similar?

https://www.ebay.com/itm/C-band-Dua...can-fixed-2pcs-C-band-LNB-on-prime-focus-dish

I have a fixed dish on 58W and was thinking it might be suitable for adding an LNB for 55W, but I can't figure out how I would attach it to the fourth arm on the dish.

Is it intended to just hang on three arms? If so, that doesn't seem very stable and I'm not sure the three dish arms would keep the two LNBs in the right position.

I have samples of this unit and have thought of stocking.
Dual mount


Personally, I prefer attaching a 2nd scalar with flat straps as the feedhorn will have a proper scalar and accommodate optimized placement on all axis . The key to proper installation on a motorized system is to align the 2nd feedhorn at the correct angle to the polar axis. The slot allows for AZ offset, but not EL. Sometimes the feedarms or a buttonhook design allows for a slight twist to align the feedhorn vertical placement to be at the correct convergence point for the offset from the polar axis.
