Could you clarify where the '1mm Tight Internal Radius' is measured? Specifically, does this refer to the internal bend where the handle wraps around the plywood corner? It seems to me it is an important information as it is reported in the item title.
The 1mm radius is where the handle meets the corner of the extrusion, not the plywood due to the fact that the handle has an offset.
Please see this drawing to further clarify. Iif you have any other questions, please email your nearest depot.
