How strong are Fischer DuoPower wall fixings?

Today I'm showing you how I use Fischer DuoPower wall plugs. These are the 6mm x 30mm plugs used with a 5mm screw. Used in concrete block, aerated 'thermalite' type block and 12.5mm plasterboard (drywall). As usual all tests are axial load tests showing peak values with no safety factor. Always follow manufacturer load ratings.
