Hi all,
I recently replaced the cones/cables on our 1987 garage door but in the process lost one of the shaft-lock grub screws so it's currently held on one screw. Easy to source but I can't find details of the thread on the web, Henderson were unable to help. Anyone know the thread size?
Many thanks,
Iain
