Questions & Answers

Can I use to secure a 2x4 to existing concrete

I am looking to frame a screen door (not support structure). Can I use this to secure the 2x4 to existing concrete? Is there a base for a 2x4 which elevates the 2x4 like post bases for larger wood sizes? This is the best I see.... Thank you.
Asked by: Dave
This one is for a 4x4 post, they do make something similar for a 2x4. If you were to use this one, you would obviously have another 1 1/2"- 1 3/4" gap between the 2x4 and the other side of the bracket. Maybe if you doubled the 2x4 up, use a filler piece.? Hope this helps

Can I use this for a gate latch

I have a wood landing out my back door, basically a small platform, maybe 4 foot by 6 foot, with a railing around half of it, one side open, and one side the house. I would like to use this to put a post to hold the latch, so I can attach a gate to the railing on the other side, would this support the latch post (which would be right next to the house)?
Asked by: Neal
The latch post would have to be secured to the house to insure stability.

Is it acceptable to install this upside down?

I would like to secure the horizontal section to the 4x4 post and then straddle 2 2x8s. Is this acceptable? I am looking to hide the hardware as much as possible.
Asked by: Derek
No, these are not designed to carry the load if installed upside down.

Can this be used as a railing post base face mounted onto the deck surface?

Can I use this to mount my railing posts onto the deck surface as long as there is sufficient blocking under the deck board?
Asked by: Dan
Yes, they will work for that application.

ZMAX Galvanized Half Base is rated 4.2 out of 5 by 105.
Rated 4 out of 5 by from It will suffice While building a railing atop my wooden deck, these were used to stabilize the 4x4 posts (as I used 6x6 posts beneath the deck.) These do serve their purpose, however they are more wobbly than I had hoped. (In case you're wondering, I did attach them to the deck in all four pre-drilled locations each & attached the posts in all six pre-drilled locations using 3" galvanized screws on all.)

We bought this product to secure 4 x 4 wood posts for our new deck railing; however, this product did not safely secure the posts on a wood deck. Unfortunately, I had to return. I believe if you're using this product on concrete, it might be better, but for a wood decks, no.
