David: to my knowledge Formica was the original brand /company. Every thing I read call it “plastic laminate”.
As for lowes good luck most of the employees don’t know what it is. However it is right where they put those cheap MDF kitchen counter top. They have about 6 different pattern. I like the white because It does not distract me and I get to draw lines on it that I can erase with an eraser:)
I put it on almost every surface in my shop. It’s durable. It allow material to slide easier too.
I must admit that I did some glue up on my saw outfeed table. When the left over glue dried I took a box cutter blade and scrape it off.

Caveat: They are very hard on the blade. When you score a sheet and try to snap it, make sure you do not let it bend all over the place, it will tear off; I have done that the first couple of times.

The site has measurement and a video. It is a good video.

Yes, the big hole allow the removal of the smaller fences.

And please don’t hesitate. Email any question you may have. I usually answer in the evening. I sneak some at work ( don’t tell).
