Step 3 - Insert the bottom pivot into the pre-drilled hole on the same side of the bottom edge as the top pivot. Step 4 - Measure the position of the bottom bracket so that it corresponds with the drilled hole where the top pivot is installed. Step 5 - Screw the bottom bracket to the corresponding jamb and floor. Step 6 - Adjust the height of the door by lifting the door panel and turning the threaded rod off the bottom pivot. Insert the bottom and top pivots into the bottom and top brackets respectively. Step 7 - Adjust the top bracket inside the track into place and secure it with the screws on the top bracket. Step 8 - Press the guide wheel to position it under the track and release it, making sure the guide wheel goes into the track. Step 9 - Gently pull the door to fully close it, and check that the guide wheels and pivots of the door do not disengage during operation and that the edges rub against the door frame.
