Door Opener
Door Opener is designed for most pull and push public door handles that are hook shaped. It will not be suitable for round door knobs and custom thick door handles. An example is shown below.
Hook the handle of the door by sliding the handle in between the two prongs of the Door Opener; whether it is a pull or a push door, this action is the same.
Align Door Opener so it is parallel with the ground and so that it rests on top of the handle.
Using gentle force, push downward and inward in a quarter-circle motion to turn the door handle completely, all while keeping your skin from coming in contact with any part of the door.
Depending on the door: If it is a push door, maintain gentle force and push door outwards, using the back prong and front portion of the Opener as support. If a pull door, simply pull backwards towards yourself, using the front prong for support. The example shown is a pull door.
