Dispel so once and for all the myth that most hinges are installed on a door more the load capacity increases in proportion. Radial load fdoor x d1 fext x d2 dhinge multiply fdoor with the difference between dhinge and d1. Using a hex wrench open the spring so you can see the tension pin. Adjusting a spring loaded hinge must be done with the door closed.

You can then remove the hex wrench and allow the spring to naturally unwind. Multiply fdoor by d1 and divide by dhinge. If the open doorknob is on your right side it s a right hand door. If it s on your left side the door is left handed.
