All 3 grades (residential, commercial, and industrial) have less than 4 inches of spacing between each pair of vertical pickets… on our aluminum fence panels and gates. Medium and large dogs won’t be able to get through; however, we cannot guarantee that an aggressive animal won’t be able to breach our products.
For small/tiny dogs, we recommend either:
- Adding our optional dog/puppy panel (short pickets) to all of you fence panels and gates. You can easily do this on the product pages, or
- Order our Style 7 or Style 8 fence and gate system which has double the amount of vertical pickets (1.5 inches spacing).
For deer and wild animals, you cannot use residential grade. Instead, use Industrial grade because the vertical pickets and horizontal rails are much, much larger and thicker.
We have a customer in New Mexico that used our 10 foot high fencing/gates to keep mountain lions out of her backyard.
