Customer Reviews

Z-MAX 4 in. x 4 in. 16-Gauge Galvanized Adjustable Post Base is rated 4.3 out of 5 by 10.
Rated 2 out of 5 by from Way overpriced for what they are. At over twenty dollars each, these should be way more ruggedly built, and have a much higher quality galvanized finish. I replaced a half-dozen of these for a customer who couldn't believe that the last ones had only lasted six years before literally rusting to pieces. I would have rather used a different product, but this was all that was available at H.D.

Rated 4 out of 5 by from A good product A bit pricey, but rock-solid when used with the proper anchor bolts in concrete. These were used to mount a decorative railing on a slab porch.
