Garador Double Door Link ArmsUpdated 4 hours ago
Unfortunately, the link arms for DC, CM, DR and Type R doors have been discontinued.
To get your door working again, you will need to overhaul the existing mechanism with a retractable door gear.
For most wooden and GRP (Fibreglass) doors, a heavy-duty door gear will be required.
To determine which door gear you need, you will need to know the weight and height of the garage door.
Guides to which gear you will need are located in the description.
