I have two free standing wardrobes, 2.8m by 2m (depth 70cm). Actually inside the wardrobe there is one internal 'wall', halfway 1m, so it divides each wardrobe into 2, but is no stronger than the side 'walls'.
I would like to remove the back board
(for ventilation purposes and to keep an eye on possible mould)
but I am worried about racking
(when a rectangle box structure slides horizontally forming a diamond before collapsing...).
What are my best options?
I thought about using internal L brackets, similar to shelving brackets, I have some industrial strength ones to hand for 60cm shelves (with a diagonal support within the L). Could that work? Would I need to support all four angles? IF I use internal L brackets should they be longer? Or if these brackets are overkill, let me know because i don-t want to waste these shelving brackets!
Or should I go for four strips of backing plywood to place within the original backing board grooves? (a piece along each vertical, and each horizontal) So a a partial back board by at least with this some of the wall behind is visible.
Or.. the fact there are two wardrobes, shall I join them?
