Customer 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 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, should be fine. Just as long you support the top to something else, post, railings, etc.

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
Yes in a way, Its a great way to fasten the bottom of the post to the porch (platform), but you would still need to fasten the top of the post to something, house, etc. This bracket is not sturdy enough to hold the post from leaning over. Hope this helps.

do you have case prices

Asked by: Anonymous
Yes they do have "contractor packs" not exactly sure how many you have to buy to get them at a lower price, but they do offer them.

This base was exactly what I needed for anchoring several 4"X4" posts onto the new porch extension I built for my handicapped brother-in-law. It kept the post securely adding strength and rigidity when it was tied in with the roof overhang. It was easy to secure it to the flooring and the only drawback was having to whittle a small amount of the 4X4 on 1 side to fit snugly inside of it.
