Single spring system on a double car garage door is great for customers on tight budget. I highly  recommend installing a double spring system because in the event one spring breaks it keeps the door cables tensioned to allow the door to still operate with a little assistance. Double spring systems last 3 times longer and keep the door from possible free fall disaster!
