Door Check, #VS2000 Standard Spring 50N (Satin Chrome)

Heavy duty piece of equipment works well. Install instructions are pictures (no words) and it took a while to comprehend, especially when it describes lining up bottom of the L-shaped cutout 2mm (being American, I had to google that into inches) above the top edge of the door. I also initially missed that this is supposed to be located near the top center of the door and not near outside edge. Suggestion to Manufacturer to Improve Install Process: (1) Place a cardboard template inside the box that shows where the 8 holes are to be drilled so that one achieves optimum alignment between the two pieces. (2) Provide the metric allen wrench needed to adjust the spring strength -- save me a trip to the hardware store. PS - If you need to remove the main body of this thing from your door, there are no instructions how to do this and all of the screws are concealed. I discovered that sliding a putty knife under the lower edge and then lifting up was the solution.
