Our straightforward instructions will enable you to measure your door to make sure that the Express Change Yolodoor is perfectly suitable for installation.
Take the 5 post-its and stick them to the side of the frame so that they are easily accessible. Use the 5 post-its to roughly mark out an imaginary cross. Place the first post-it in the upper centre part of the door; the second approximately half-way up the centre; the third also in the lower centre part of the door and the fourth on the right. The fifth is placed by opening the door and attaching it to the inner frame leaf. Close the door and draw a line as close as possible to the frame, which will be used later to measure the thickness. Now you have your imaginary cross.
Take the first measurement of the upper part, from the right of the door to the centre, and mark it on the post-it: 400 mm. Continue on the top section, from the left of the door to the centre. In this case the measurement is 403mm. Note it down and add the two together. 400 + 403 is 803mm.
For the fourth measurement, calculate the height. A measurement of 1600mm recorded from the base of the door is noted on the post-it. Measure from the upper section to the mark and note down the result. In this case, mark 425mm on the post-it and add the two together. 425 + 1600 is 2025mm.
