I have a client who wants a couple custom baby/dog gates in their home. One of them is at the bottom of a walled staircase and the gate will have to swing around 270° to the other side of the wall.
Here's an illustration of the set-up:
I've seen a lot of 270° hinges for cabinets, but they are all designed to be mounted on a 3/4" cabinet box, while this will have to be mounted on a 5" sheetrock wall end.
Keep in mind that it needs to be somewhat stylish. I'm building the baby gates to match the existing stair rail that is stained wood with white balusters. So something like wrought iron or oiled bronze is what I'm going for.
My first exploration leads me to perhaps consider exterior gate hardware or exterior shutter hinges.
Hinge suggestions, anyone?
