What does "on backorder" mean?
If your C16 part number says next to it, those items have a 3 to 4 WEEK lead time for the month of September. Backordered items are only built to order, if there is no order pending for the item we will not build and stock it.
Varilock and Washing Machine parts may have an extra lead time depending on what Suspa location they are coming from.
Table lift systems lead time does vary, generally it is around 4-5 weeks currently.
