The extract parts were delivered quickly and were as described. The assembly also was no problem. What bothers me a bit is that the statements in the oven do not stop at the back. This may make you as much push back to abut the sheet metal of the rear oven wall. This in turn generated during operation of the furnace sometimes a rattling noise which sometimes disappears when the extracts slip slightly forward. Otherwise you have to open the oven again and pull slightly forward.
