This will depend on the type of the material of the rotary washing line. If the rotary washing line has a metal ground spike, it will not require concrete. If the ground spike is made of plastic, it will need concrete. Here are the installation instructions for a plastic ground spike:
1. Choose where you will place the rotary washing line, if possible in a sunny position and not under a tree or over a garden path. Make sure there is enough space to unfold and rotate the washing line
2. Remove the piece of grass then dig a hole 35cm- depth and 30cm wide to add the concrete
3. If there is no closed base on ground your socket, place some tape over the end to stop any of the post mix getting underneath
4. Put the ground socket underneath in the hole, then half-fill with water, then add the post mix as the manufacturer instructions
5. Check the ground socket with a spirit level to keep it straight and ensure it is supported in this position for at least 5 minutes
6. Wait 72 hours for the concrete to be set, then insert the clothes line into the ground socket and test
7. You can use the piece of grass to cover the concrete base or use soil
Essentially, you measure a rotary washing line diagonally across the wingspan, we have many different styles and models so they do vary.
If you look at our Brabantia washing lines, we supply the dimension image online, so you can find it by clicking on the product image.
It will depend on the size of your family, the frequency of washing and the type of laundry you’re going to dry. On average, our lines measure between 26 and 60m. With 40m of line, you can hang 4 washes. This approximation will be different if you’re hanging bed sheets or towels, as these textiles are much larger. A 60m washing line will allow you to hang king size duvets and sheets without having to fold them for your ease.
