Finishes Available - Brass Satin Nickel Dimensions - Length - 117.5mm Width - 28.6mm Depth of plate - 10.3mm Minimum thickness of timber / metal - 41.3mm Identifying the correct hinge. 1. Determine the width, thickness and height of the door. 2. Once the above is achieved see the PDF 'Technical Data Sheet'. Locate the width and the weight of your door and draw a straight line through those two points, continuing the line on to the left hand edge of table 2. An example of this has been illustrated by a dotted line for a door 800mm wide and 85kg in weight. 3. Where the line meets the left hand edge of table 2, draw a horizontal line the full width of the table. This is determines your recommended hinge. 4. If you look at the dotted line this meets a light blue box, this indicates that if your door has a minimum thickness of 41mm then you can use 4 hinges type 218, or, if you follow the line through to the next column because your door has a minimum thickness of 48mm then you must use 3 hinges of type 220.
