1 ft. H x 4 ft. W White Modular Vinyl Lattice Fence Panel (4-Pack)

We used this to enclose the bottom of our backyard deck so my dogs and other critters would stop going under there. It worked perfectly! We bought 3 sets to go all the way around and the quality of the lattice is nice and it's definitely sturdy. I love that the 'openings' are small so nothing can climb thru it.

I got these to close up the space under my new 8x14 shed. The grid opening is small, less than 1.5 inches diagonal, which should stop most wild life getting through and make a home under the shed while still allowing for ventilation. The package contains more panels that I actually need, but that is OK. I intend to cut the panels down the middle so that I have 48" long and 6" high sections.
