I would see if a glass shop would have this. Can't recommend a place as I'm out of the area.

Purchase a piece and cut to fit yourself.

We have a wood dining table that we used to have covered with a glass topper. We like being able to see the wood, rarely use tablecloths, but want to protect the finish of the wooden table. We would like to switch to an acrylic or plexiglass for when we have the leaves in because glass would be too heavy to move/remove to clean. Any suggestions for where to source? It a very large and unusual size and can’t find anything prefab online in the dimensions we need. Thanks!
