The End plate is the main steel flat section that holds the barrel and the weight of the curtain, this makes this a very important part of the door, and it’s also the crucial part that attaches the motor or hand chain assembly.
If you require a replacement we would need details such as plate width and height, also the thickness.
Due to the wide range used a photo is also helpful.
There are other parts of the door also referred to under the heading ‘Plates’ these would include the motor mounting bracket, the top hat bracket or foot mount for the inertia brake.
