I have acquired just the frame part of a swing chair and I need to buy the fittings to attach the chair onto. I’ve searched to see if you can buy a hanging egg chair bundle of fittings but I suppose they come with the frame and chair majority of the time so there’s no need to sell separately. I can buy the spring and chain easy enough but I cannot find a bolt with a hole in the bottom like that, does anyone know what it might be called?
Hopefully photo is attached
