I have lived in rentals for most my pole career. I’ve done my share of filling holes in many ceiling where the pole was mounted. I like to use a pole mount instead of the domes that come with the removable poles.
The two spaces (both shown in the video) had carpeting and I wanted hard flooring but we were renting. My husband got creative and we did this DIY flooring. Again, the plywood and flooring in this video was used twice and held up just fine. I sold the plywood and gave the flooring away when we moved, as I didn’t need it.
