Since we installed out central AC two year ago our stairs haven't been right. they stick when we pull them down. Not sure if they put them back together wrong or they are bent. Can you provide me with home help as to how I fix them. They are currently stuck and I can't even open them at all.
Looks like a relatively simple fix. You should be able to just bend it back to shape and at least get it semi functional without needing to do too much work.
Have a pair of pliers that you can grip and apply pressure to the metal with?
