I am interested in the Twin 60 door runners I need to run 3 doors on 2m of sliding door track. Your info states maximum door height is 2 metres. My door height would be 2.110 metres. Can you please tell me if they will work at that height, if not is there an alternative?

The 2m height is only a guideline, and 2.1m should be perfectly okay as long as the doors are rigid.  The most critical consideration is the weight of the doors – as long as they are not more than 25kg each, and between 16 – 40mm thickness, then they will be fine.

I am using 2120mm high doors (PVC edged – 18mm board) at 560 wide. This is above the max height recommendation of 2m for the ‘twin 60’, will this be ok? As a matter of interest (for future reference) would I be able to use the ‘Jason Bottom Rolling Sliding Door Gear’ for doors of 2120 x 560 (18mm). Again I am aware that the height is well above the recommended 1.5m but I believe that the weight of the doors themselves would be less than the max 25kg stated.

The maximum dimensions of doors for Twin 60 and Jason recommended by the manufacturer Coburn is a guideline only.  According to Coburn’s technical department, it was laid down by the original designer of the system and any evidence & reasoning for them has been lost to time.  The weight is by far the most important measurement of the door.  If your doors are MDF then, at 2120 x 560 x 18mm, your doors should weigh approximately 17 kg each.
