I have an old line, the posts are 2156 apart inside, and 4cm wide.
Bolts are 17cm vertically apart.
About 12yo, it doesn't really open and close smoothly and even trying to oil it I can't get it to open and close well at all.
If we were to get something new in the same style, is it possible to keep the same posts and just change the top part? is there any type of standard?
this came with the house so I do not know what brand it is but it is a Mirvac project home.
When choosing a new one, how do I get one that lasts longer? I do remember old rotary ones lasting decades and moving smoothly.
Alternatively can they be installed directly into those aluminum posts you can see holding up the fence behind, save some space?
Is this a DIY or will I have to get someone in?
