Light Weight and Low to the Ground

Would Recommend

If I had used pre-cast concrete deck supports, I would have had to dig small holes to place them in, in order to get the deck as low as I wanted. This product, in comparison, holds the boards quite low to the ground, which allowed me to get the deck as low as I wished. The light weight plastic is much easier than working with heavy concrete. Poured footings and heavy concrete blocks have their place, but this is a great alternative in many situations.

Sturdy, Quality Product

Would Recommend

I used these plastic deck supports on my new front porch. I originally picked them because of their shorter height than the cement supports. However, they work great - they are sturdy and easy to install. The only issue I have with them is that I now have to figure out a way to cover the parts of it that are showing since I don't like the look as much.

Better than other brands.

Would Recommend

Blocks are lightweight and easy to install. They are smaller and more compact than the other brands and do exactly the same thing.
