Pictures.....Say, "Spring Loaded."
Install strut on door first, hold door open to point where you'd like the door to remain open when using the power of the strut. Swing strut into position on cabinet support and mark screw hole using hole in strut. Unless you have solid wood cabinets, don't forget the long screws. I used the short ones and you can see the mess I made. My cabinets are made of some fake-a-loo (pressed sawdust) stuff covered with pretty plastic (.002 thick) veneer. Have fun.
Oh yeah, I'm using only one strut per door.
