Spare Thick Door Clamp
The 10mm thick clamp of which there is one in each new style runaround door. This has now changed shape and includes a square cut for the sliding door key. There is an option now to use circular spaces in place of this as we do on the base of the door already.
From September 28th 2015 the door changed to Mark 4 so the clamps also changed. Be sure to choose the right spare clamps to fit your door.
Any doors previous to this will fit Mark 3 parts and the change of shape does not affect the fit.
