But make sure they are set to the same tension for one door. Attention: ·Come with both machine screws and wood screws, so both 1-3/4'' and 1-3/8'' thick doors applicable. ·Make sure the door is in closed position when you adjust the tension. ·Always rotate the tension adjustment rod or hex wrench to the left regardless of right-hand or left-hand door application. ·After final adjustment, drive the pin flush with the hinge barrel . ·You cannot make them self-opening by adjusting the tension to be negative.
