Clearview offer three different add-on's (extension profiles). They are 15mm, 25mm and 50mm.
Selecting add-on profiles is done in two stages. Firstly by choosing which size, and then by the position it is needed in whether it be the top or side or a combination thereof. The overall size given in the previous step is the size that the door will be made to incorporating the add-on requirements.
For example if the size entered is 900mm x 2100mm a 25mm add on is selected to the side then the door will be manufactured to 875mm wide so that the 900mm is achieved with the 25mm add on.
