This is our patented 3/4" binding tape block, and it's designed to apply 2 strips of 1/4" seamstick tape to one side of 3/4" binding. Also, you can feed the tape to only one side of the block based on your application. With the removal of a single bolt, you can easily and quickly change out the tape block of your Seamstick Taper Tool.
(Note: the color is not item specific, and may come in a different color then shown).
*** This tape block comes with a size specific spool of the same color, the black spool for zipper blocks will not align the tape properly ***
