1.5″ would not be available as a modification.
The issue is that, at 1.5″, we are unable to safely run the part through our edge banding equipment. The belt that holds the part is spaced away from the area where the banding is applied. At only 1.5″ wide, the part is barely held by the belt, which means it can shift out of alignment and potentially damage the equipment.
2″ would be our minimum, and even that is pushing the limits.
The best option would be to order it at 2″, then cut it down on site if needed.
