Up for your consideration is a new-in-the-box Banner plastic fiber optic assembly, part number PIT4100U or 70778 or 3070778.  It comes complete as a kit, which include the instructions.  Being unfamiliar with this product, we're selling it as-is, no returns. I believe, however, since they are new they will likely perform as expected.  Let the photos be your guide.  If you have any questions about the item or the shipping methods we offer, feel free to call.  All shipping is paid by you, the buyer.  Our number on the West Coast is 541 760-8284.
