Afterthought

Company Description

Hi!I am a small furniture manufacturer in Ireland and need a hinge or pivot that can be hidden in the body of a shelf. One end is fixed to a wooden partition wall and the other slides into longitudinal hole in shelf as per attached diagram. Pushing shelf towards the wall locks the knuckle joint and pulling it to expose the joint will allow the shelf to be folded down.KEY TO DIAGRAM:1. SHELF DOWN, SPRING UNDER TENSION2.
