You will be prompted with an option to choose a left or right tab side. In doing so, you have the ability to accommodate classrooms according to the direction your door swings open.
For instance, if your door opens to a right hand reach, you will need to purchase the “Right Tab” option. Likewise, a door that opens to a left hand reach will need a “Left Tab” selection.
An easy rule of thumb to follow: Left hand doors have hinges located to the left. Right hand doors have hinges located to the right.
