One of my side gates has had a problem for years.
There is a 3' & 5' gate & the 5' one keeps sagging.
I have moved the catch then it moves lower. I moved the heavy hinges but it sagged again.
I always blamed my kids for climbing on it.
I added extra bracing but it's down another 2" now.
I finally realised the problem.
They're interwoven gates to match the fence.
The builders hung the gates so the Z braces were the same.
i.e. |/||/| when they should have been |/||\|
To think. I should have noticed this years ago.
I should have rehung the offending large gate but I already bought the timber to make new shiplap clad ones. At least I know how to stop this happening again.
I'm also making sure the hinges are high enough to keep away from all but the tallest dogs. lmao
