The ISSUE with old style system "ONE PIECE" doors, is that PRESENT TIME, they're VERY DANGEROUS, the springs exposed on the sides probably rusty and old, could snap any moment and if someone's in there or you have valuables, it could be hazardous. WE STRONGLY RECOMMEND THAT IF YOU REALIZE YOUR DOOR IS RUSTY AND OLD, DONT HESITATE IN GETTING A NEW ONE, SAVING A COUPLE BUCKS COULD END UP WORSE.
A way better option right now is a:
~Lighter, sectional, roll up door.
~Basic, insulated or steelback.
~ Top windows or side windows.
~Clear, frosted or tinted windows.
~White, beige, gray, brown or black color.
~Long rectangle or short square panel style.
~Automatic or manual.
