I have been looking for slat/slot wall brackets of a particular length on and off for a few years but I am really struggling to find more of them. I will buy them anywhere but I simply cannot find them online or with shopfitters I have tried.

I need 12 x 27cm brackets and 30 of the metal "feet" (not so important) pictured.

Brackets in question..


Note: these cabinets do not have enough depth to hold the 30cm brackets.
