Garage doors are crazy.

Like, you can kill yourself trying to perform maintenance on the primary roller spring if you don't know what you're doing.

They're also crazy delicate and become completely useless if anything gets slightly out of alignment. 

 YES! I had one of those springs snap while in the garage. Thought a gun went off 🤣 Thankfully I didn't get hit by it.

My garage door is almost 50 years old, manual, solid and maintenance free.
