This is a friendly reminder for you to check over the equipment on your overhead doors.
The lift cable on one of my roll up doors snapped today. I DID NOT have a safety cable through the spring and the spring assembly flew off and hit the recycling pile.
For some reason the only the interior springs had safety cables through them. Of course the outboard lift cable is the one that snapped.
I picked up new lift cables for both doors and have repaired the inoperable door. I ran a safety wire through the outboard spring so now both springs on that door are safety wired.
I'll take care of the other door tomorrow night - it gets a lot less use until winter when I pull my car in nightly.
So give all your cables a look over, lubricate the rollers and tighten anything that has loosened back up.
