I'm going to place a wooden box/cover over a cabinet on the house wall. Think of a larger birdhouse without a back and bottom. It should be easy to unhook.
I'm trying to find a suitable fitting for this and was thinking of something similar to those that hook together the parts in a detachable corner sofa, but smaller and for outdoor use. See attached sketch.
Intended dimensions, about 15-20 mm high, 60 wide.
However, I'm not finding anything suitable. Does anyone have any tips on what I can buy or should search for?
