Stainless railing won’t fit in anchors

[FrankM]

Had a heck of a time getting my railing out at closing last year. Now it won’t fit in the concrete anchors. Anyone deal with this before?

Did something grow corrosion? Sand it off.

Or did someone tighten up the retaining wedges after removal?

It seems like the anchors somehow got smaller/tighter, I don’t know how to explain it. I’ve sanded off corrosion, tried CRC and pool lube. Tried to force the railings in and actually reshaped the bottom of them. The retaining wedges are not the issue, I removed them as well and it still doesn’t fit.
