If you are having problems locating a replacement part for your garage door, please contact us, as we do have a network of manufacturers and suppliers which we use to get unusual and discontinued parts and spares. Also, sometimes manufacturers will discontinue springs etc, but it is possible to use another manufacturers spring to do the job, this information is not made public that it is possible, but we will have the relevant information to find out which part will do the job as the manufacturer originally intended it to do. So, if you are having trouble, either give us a call or send us an email (details found below in our 'signature') with a picture of the parts you require, attached. We will do our best to help.
