With the black 11" high and 1 ¹/₅" wide Duplo spine tape strips you give your DB-290 perfect binder more versatile by adding the ability to tape-bind as well. Also called strip binding, this will add a fabric strip to the spine that wraps slightly around the front and back to bind your pages. This allows your first page to be the cover, and is a popular choice for machine user manuals and training guides. The tape features a pre-applied adhesive, and utilizes the DB-290 adhesive to create an extremely strong bond. To apply, peel off the center liner, bind as-normal in your machine, then peel off the side liner strips and press onto your book covers. You can buy tape binding strips for your DB-290 online.
