Extra Module for Raised Bed
Get a little bit more wood for your single, double, or triple raised bed with an extra module. These are available in various heights i.e. 15cm, 30cm, 45cm, 60cm and 75cm and across widths of 25cm, 50cm and 100cm.
One of the benefits of buying extra modules is that they come with 4 posts but because you already have your own existing raised, you end up with 2 spare posts that you can use as a back-up or for other needs.
