How to fit the Foxdry Mini to a modern plasterboard ceiling when you can't find the joists or if the holes are in the wrong place.
I made two load spreading plywood plates 9mm thick and 16cms by 16cms.
Instead of using the supplied screws, I used 2 bolts to attach each ceiling clamp to the plates. Then I used 4 countersunk screws in each plate to screw in to Fischer Duotec plasterboard anchors.
