- If you want an inside return and an outside return on your trim - adding an outside return will reduce how far the inside return goes into the wall cavity. As an example, if the outside return is 20mm and you want 50mm of the inside return to go into the wall cavity you will require an inside return of (50mm + 20mm) = 70mm.  The minimum inside return size is 10mm

- If measuring internal width and internal height of an old trim - make sure to measure from the front of the old trim. If you measure from the back of the trim you may include the thickness of the metal which would add approximately another 5mm onto the height and 10mm onto the width resulting in the final trim not fitting.

- When we refer to width and height measurments - We are always referring to the internal measurements. External trim measurements would be calculated by using the following formulas.   

External Width = Width + Face + Face + 8mm       

External Height = Height + Face + 4mm
