Anchoring a Residential Fridge

Use some metal straps, attach them on the back of the fridge and screw them into the floor from the back in the places you can reach via the exterior. If you don't have an exterior access point then build up wood retention area in the front and top to keep it from falling forward on turns. Obviously secure in other places where possible.

if you have access under where the heater is you can drill and replace the feet with nuts and bolts then in the back use a couple conduit clamps around the back frame.to holdthe door closedi made a swing arm on the non hing front foot and a l bracket i slide in the top use a bungie chord

My friends used rachet straps and eyebolts thru the floor. Where there wasn't room to operate the rachet mechanism, they used a chain (padded the chain with non-slip drawer liner & protected the corners of the appliance box with "L" shaped metal pieces) that looped from an eye bolt thru the floor on one side to an eye bolt thru the floor on the other side. They tightened up the chain from under the floor. They did this a week later to take into account the chain stretching. The appliances haven't moved at all. Pretty good considering they promptly put the bus into an abandoned store parking lot that had a good 12" drop. Downside to the setup they used was that it takes two people (one inside, one outside) to tighten up the tie downs. I was happy to help. Hardest thing was getting back up off the floor! :D

We used 4 lag bolts through the bottom to the subfloor, but even that is, IMO, an accident looking for a place to happen. So, we also added 2 straps from side to side that hold it firmly in place and keep the doors closed while traveling. Very easy to use and when we get to our destination, just tuck them along the side of the fridge and most folks will never notice them.
