Face your door from the inside so that the door opens in towards you. If the knob is on the right side of the door, the door is a right-hand door. If the knob is on the left side of the door, the door is a left-hand door.
How to Measure
Order by opening size. ClimateGuard doors are manufactured to allow for minor variations in opening size. The chart below shows opening size ranges that will accommodate our standard size doors.
Measure the opening width at the top, middle, and bottom of the opening. Record the smallest dimension.
Measure inside height from head to top of existing threshold. Add height of threshold above finished floor. Record the smallest dimension.
