Sorry I didn't see your message until now. I used toggle bolts but not real confident they will last. I am following the post on using the plywood for a permanent fix. I just can't believe the factory thought screwing into a thin plywood would hold the refrigerator that size. Good luck on your repair

Hi CDS1. My bracket also pulled out of the wall behind the fridge. How did you reinforce the wall? I'm looking for ideas before I start. Thanks
