Bifold Door on a Narrow Threshold.

[charliegolf]

I'll shortly be fitting a bifold onto a sips threshold, and I"m worried the timber at the front edge of the sip, closing off the panel is a bit narrow.

The 'shed' is going to be counter battened for cladding. Can I move the door forward an inch into the batten space, to ensure the threshold screws go into meaty timber. (the sides and lintel are fine)

Thanks.
