Can I safely anchor framing to 45x45in columns and floor to replace a banister with a half wall, considering a 200lb sideload?

I’m thinking about swapping out my banister for a halfwall. Do you think it’s okay to anchor the framing to these columns/pillars? They’re 4.5×4.5 inches. What’s the best length of screw to use and how many should I aim for? I know it needs to withstand a 200lb sideload. Any advice or alternative suggestions would be greatly appreciated. (I have a drawing for reference, but it’s not to scale.)
You totally got this! Just grab some 3 inch screws instead of drywall screws haha.
Thanks for the assistance, . I really appreciate it.
I think you’ll be okay. Those posts seem to run from the floor all the way up to the ceiling beam. Opt for sturdy, long screws. You might consider adding an additional top plate to your half wall for more support. It’s also a good idea to have a continuous bottom plate along the base of the new stud framing.
Also, a continuous top plate is important… I mean, that’s a no-brainer but… haha…
I believe using brackets (similar to a joist hanger) instead of screws would be better. Have you checked out any videos on how to install a structural pony wall? You might also want to refer to the construction code & see what they recommend. (It may need electrical outlets if used as a wall.) The required height can differ depending on the location.
You actually don’t need any brackets for that. Plus, I doubt there will be a permit needed, so who cares about outlets, haha.
Hey , absolutely! Thanks a lot for mentioning the importance of having enough space for additional outlets.
To meet code requirements, use 3” 16d framing nails every 12”. A common practice is to alternate two nails, followed by one nail in the center every 12”.

‘t forget to grab some 3” construction screws with t-25 heads.
Thank you so much, it means a lot!
No worries dude!
You don’t even need brackets or anything special. Just use 3 1/2″ framing nails or equivalent structural screws. There’s really no need to worry at all. Simply remove your railing and frame in your new wall in between. If you want to be extra cautious, you could also add some 3″ ledger locks into the posts and floor for added peace of mind 😊
If the current posts can support the existing railings, there’s no reason why they can’t handle the same side loads for the new knee wall(s). Consider adding a knee wall attached and screwed to the posts and floor for extra stability. Removing the non-code compliant railings is a good move, especially with the unsafe spacing between balusters. Adding more balusters to the remaining railings is recommended to prevent falls, keeping the spacing between balusters at a maximum of 4″.
Indeed, I agree with his point
Absolutely, and thanks a lot for your encouragement. This house has some questionable design choices from the 70s. I’m really eager to start making improvements!

Opt for nails instead of screws.
Screws are in good shape
They are commonly used to frame walls in the construction phase, right?
Many opt for a nail gun for its speed, but speed alone doesn’t equate to quality.
Has the skills and knowledge to construct without nails or screws, so it ultimately depends on availability and motivation to ensure durability.
You know, you can actually break a screw with just two strikes of a hammer. Unlike nails, no matter how many times you hit it, you won’t break a nail. They still haven’t made a screw stronger than a nail.
Well, why not start building everything out of steel? Who in their right mind would choose wood over steel, which is clearly much stronger? Or how about we all boycott nails – this guy has really opened our eyes to our mistake in using screws.
Hey, did you know there’s actually a practical use for screws? But framing is definitely not one of them.
Haha… indeed it is, even if you’re not a fan.
I genuinely couldn’t care any less. It’s not my house.
Is observing the type of screw here.

I’ve heard of those. Let’s see how using them for Framing inspection in Georgia goes for you.
No thank you. However, if I were working on a project in Georgia that required screws, I would definitely use them.
Absolutely, you can definitely proceed as you mentioned… go for it, and be sure to add a nice cap to the wall. ‘t forget to share some photos after you’re done!
I appreciate the reassurance, I’ll definitely share some before and after photos.
Hey everyone, just wanted to say thanks for all the comments and advice! So glad I joined this group.
How far apart are the balusters? My big head could probably fit through those gaps.
Oh wow! I can’t find the measurements right now but yeah, it’s definitely not up to code and needs to be fixed. The house was built in the 1970s and has some quirky features.
Pre-build a frame with a top and bottom plate, a stud every 16 inches, screw to the floor and to the post. You may want to double up on the top plate.
Have you considered installing a glass wall?
Wow, that’s a neat idea, . I’ll definitely be sharing this with my wife.
Make sure to check whether it’s a steel post or wood first
