Have you thought about it to ditch that plastic trim and just use angle beads? Then get a plasterer to finish it then you can fit your pivot hingesThe Dutch, the Americans and Germans all use very expensive pivots, not suitable for 35mm light hollow-core doors. I'm looking for cheap door frames for low cost pivot doors. The frames should be for doors in 'square-set plaster' work. This may be an Australian trade term that is not translating well. The PVC 'Trimtex' frame only suits 90mm walls. I'm hoping somebody knows an alternate brand for more sizes.View attachment 24545
