MeasureA steel doorset is always ordered by the OVERALL dimensions including the door leaf and outer sub fixing frame with no tolerances allowed for. Most people would generally allow 5mm tolerance all the way around the door, but it all depends on how square or true your aperture is on site.
This means if your structural opening size is measured as 1000mm width and 2100mm height the door and frame ought to be 990mm wide and 2090mm high with the frame and any threshold included.
Always measure the top, middle and bottom of your aperture width and the left and right hand side for the height and if possible do a measure to make sure the opening is square as well.
Always use millimetres for measuring as this is how we relay back the ordering dimensions to you for checking and approving a drawing for your order.
The Robust Tuff-Dor does not have the normal 30mm adjustable fitting frame but does have a 3mm chassis system extension.
