I'm going to screw it down to pieces of wood and that should make it solid. In the instructions it says you can get replacement parts by phoning 0121 506 0008 or by emailing
alanuk@keter.co.il but I don't think I'll bother as it should be fine when screwed down. Before I do that though I'll have to be careful that the other side doesn't go too otherwise the top ones will go next
