I see the fillers can be ordered in small incremental widths starting at 2 inches.
If i need a 1 to 1.5 inch filler, can I assume the plywood based/laminated 2 inch filler can be scribed to fit the space?
Yes, you can cut them down to under 2” if needed. 2” width is our minimum as anything smaller would be too narrow to run through our edge banding equipment (smaller than 2” width would not touch the rollers and possibly jam).
