A WELL BALANCE
D GARAGE DOOR WILL LIFT EASILY AND WHEN RELEASED AT ABOUT 4 FEET ABOVE THE FLOOR WILL STAY AT THAT POSITION . THE GARAGE DOOR SHOULD NOT, AT ANY POSITION, DROP OR LIFT BY ITSELF. TYPICALLY THE GARAGE DOOR WILL SLOWLY DROP AFTER BEING PULLED DOWN. IT SHOULD NOT DROP WITH ENOUGH FORCE TO CRUSH A PERSON'S FEET OR DAMAGE THE GARAGE DOOR. THE GARAGE DOOR SHOULD ALSO MOVE WITH THE SAME FORCE UPWARD AS NOT TO SLAM INTO THE GARAGE DOOR OPENER OR BACK STOP. THERE IS USUALLY A BOLT ON THE END OF BOTH TRACKS TO PREVENT THE GARAGE DOOR FROM RUNNING OFF THE TRACK.
