Next, straighten the panel and carefully loosen the thumbscrews to release the spring mechanism, letting the panel rise into the upper track. Then, push your panel towards the wall and inside the vertical track. You can now tighten the thumbscrews to secure the panel in place. Note: if the outer track wall is shorter, it may be easier to install the final panel from the outside. The thumbscrews and locking cover will still be facing the inside of the home.


Close the sliding door against the pet door to make sure they are level and free of any significant gaps. The weather stripping will help accommodate any small gaps. You can refer to the tricks included in your instructions for substantial deviations.
