URGENT HELP. Post brackets on L-Support

[pdov]

It's been a long time since you did this, but how did it turn out? Wobbly or stable? How far apart are the posts? It looks like you have 28x45 as slats? I don't want them to sag in the middle.

It's not as stable as my parents' fence where they cast their posts into the ground. You can budge the fence if you push it, but it's absolutely not the case that it sways by itself or even in strong winds. Here is a video where I try to show how it can be moved. Not sure if it helps you any.

If you're going to build a taller fence or want a really stable one, post brackets mounted on both sides of the wall are probably preferable.

Where the retaining wall ends, I have footings with adjustable post shoes, and it sways more, so that's something I don't recommend. Had I known this from the start, I would have chosen footings with post brackets instead.

The slats are 34x45 mm, and they haven't sagged over these three years at least.

Thanks! Nice video! My fence will be only 1m high so it should be fine. Some of my elements are only 8 cm thick, but it would take a lot for the post shoe to crack the element. Thanks again!

Some of my elements are only 8 cm thick, but it would take a lot for the post holder to break the element.

It takes a lot before the mounting damages the elements. I had similar concerns about how close to the edge you can drill. I personally chose to drill centered in the element and cut my post holders so I wouldn't have to drill too deep and reach the reinforcement.

@Fredrik86 had a different solution with more fastenings closer to the edge of the element.

It's also good, probably more stable than my solution, but I wouldn't dare to drill closer than 1.5-2 times the diameter of the hole.

There needs to be a lot before the fastenings damage the elements. I had some of the same concerns about how close to the edge you can drill. I chose to drill centered in the element and cut my post shoes so I wouldn't need to drill too deep and reach the reinforcement.

@Fredrik86 had another solution with more fastenings that are closer to the edge of the element.

Drilling in the center unfortunately went to hell, the reinforcement is in the center and already after about 7 cm.
I tried Fredrik's solution and the drill holes go on each side of the reinforcement. I'm planning to use M8 threaded rod with 10mm holes. Only 104 holes left now

Tried Fredrik's solution and the drill holes are on either side of the reinforcement. Planning to use M8 threaded rod with 10mm holes. Only 104 holes left now

Hope it goes well for you. Feel free to post a picture or two of the result, it could help others who find the thread in the future.
