Dad's garage door is temperamental, occasionally won't open.
It seems that the cable goes through the round plastic thing behind the lock and has a grub screw holding it in place. The thread that said grub screw goes into appears to have gone so I need a new one. Should be easy enough to deal with I'd have thought, but I can't work out what to search for to source new one.
Any ideas?
Could you drill/tap out the plastic to take a bigger thread & screw?
Fraid I don't know but I reckon if you email the company above with that photo you might find an answer!
+1 for bigger screw.
Or screw a threaded insert in to give a better thread for the grub screw (eg https://www.screwfix.com/p/insert-nuts-type-d-m6-x-13mm-50-pack/59937 but lots of different sizes available)
For a proper bodge, couldn't you clamp it as it comes out the plastic thing with something?
It's likely called a garage door handle cam, as that's what it is, it's a cam to provide additional leverage to pull the cables when you turn the handle.
Had exactly same issue
I used one of these, it's lasted 2+ years up to now
