Aluminum extrusion table base?

I am having a brain fart I think.

I'm looking for the thinn extrusion found in laser engraver tables. This is with t slots. Maybe 20mm thick? Searching has received 20x20 and similar frame pieces. I want a generic table fixture to secure some straps to to hole a work piece.

Thanks

If you search eBay for "T-slot 15180" you will find some, though I had not much luck finding anything wider.

Via a Youtube video I found
