This is a great opener. Has all the hardware for most standard installations. Very feature rich. Need better instructions I need to change stop / interrupt direction and don't understand the explanations in the answered question about reversing the magnets.. Need to spend some time testing. Over all this is a smooth an quite unit. I wish I had another gate to install one on.. Opens my 16' gate perfectly.. We have been using it for over 3 months now. Super Pleased!
