Thresholds For The Standard Folding Door Range
On the standard range of folding doors, the threshold has a face fixed aluminium track. On open out doors it is fitted to the outside and correspondingly on open in doors it is to the inside. You should take into account the overall threshold height when measuring your door, so that you can reduce the height of the step. The two CAD images below show dimensions for the standard and aluminium threshold. Click on the relevant links for your chosen threshold to show open out, in and buried enlarged printable images.
