Product review (5 stars): I bought an identical one like this from Lowe's
I bought an identical one like this from Lowe's. I installed in my RV's norcold n611. I left the fridge in the rv and drilled a hole tru the cabinet beside it to run the water and electric. I 1st epoxied the bolt heats to the back plastic wall but that only held for a year or so. I then got some small angle shelve brackets and used the bolts that came with the fridge  to mount it. I would not try to put any screws or holes in the back freezer you can possibly puncture something and destroy the fridge.

It works great and makes a lot of ice, but takes a day or so from a warm fridge to get down in temps.
