Cover Tape Extenders for 4mm tape widths can be used with either paper or plastic tape, punched or formed pockets, and any cover tape. Cover Tape Extenders are designed to be used for reels with no leader available or small pieces of carrier tape. These extenders are 20″ long and can be used on any feeders except Mycronic (Mydata) with take up reels or pinch roller systems. Simply adhere the extender to the end of the cover tape and peel it back to expose the part in pocket one every time.
