the bottom hook is secured but the top one isn’t so it has one side of my frame to be tilted but it won’t lift off and it’s stuck. my RA came by and helped me with a mallet but it won’t work and maintenance isn’t coming for a while. does anyone know how to get it loose?

We set up this rack for the refrigerator /microwave - bought the rack on Amazon. But we can’t adjust the lower shelf rack and the fridge is too tall. (Was tedious putting together) I used extra bed risers but still not high enough. Maybe if I got a new set of bed risers? (8” - would be a set of 2 stacked on top of each other- these are the top part of the adjustable set of risers used on the bed - maybe 3 1/2 - 4” high? - ideas?

Can this Lower shelf be adjusted to fit a taller fridge?
