Is it hollow or solid to prevent mold growing inside？

Dear friend，it is solid silicone water dam，no mold issues to worry about. Easy to clean and tidy.

We have a door sweep installed but water still gets under it. Will this work as a frameless shower door threshold?

Yes，it is 12mm（0.47 inch）high，20mm（0.78 inch）wide.If you want to use it at the bottom of the shower door, measure the gap to make sure whether it fits, because our shower strip can seal a bottom gap between 1mm to 12mm(due to its slope design). Also is perfect in no curb shower pan, walkin shower, ada shower etc.

Can you provide me with a picture how to install it under glass shower door? I mean should the high side face the outside of the shower or the inside

I don't have picture but understand your question. The high side (the straight up 90 degree side should face the inside of the shower. the side that is sloping down should be facing the outside. In my shower, I don't have a door. My is a completely open shower so when I put down the barrier, it only makes sense to put the sloping side on the outside. If I were to put the sloping side on the inside of the shower, the water can easily spill out because the slope will facilitate easily flow of water outside of the shower.

Where is this product manufactured?

China. All of this kind of dam on Amazon is made in China. But we are the first seller to sold this and guarantee the best quality.
