Garador spring & pulley assembly to suit Mk3c, S/S and Mk2 garage doors (manufactured before 1999) which have an overhead spring box with 2 springs in. Also know as Westland and Catnic garage doors. (see my other items if you require a complete spring box with both springs and cables etc)
If your spring box does not have the removeable cover, then it is not recommended that repairs are carried out, and a complete spring box assembly is purchased instead,
There are s few variations, please identify by using our spring chart. You will need to know the panel style of your door by comparing to the pictures in our chart (or looking at the label on your door), and the door size. Alternatively, check out your existing springs for coloured bands.
Please ensure you have selected the correct part, see identification chart below:
