Toshiba 6LB61737000 | BV410T/BV420T Ribbon Spindle Adapter (ASYB-SPOOL-RBN-BVT-FRU) is the original Toshiba replacement part that locks your thermal transfer ribbon securely in place inside BV410T and BV420T desktop printers. This field-replaceable unit maintains true ribbon alignment and consistent tension, helping prevent wrinkles, edge fade, and tracking issues—so you get crisp barcodes, dense blacks, and clean text while protecting the printhead.

Perfect for swapping in after wear, accidental damage, or frequent media changes, the adapter seats the ribbon core precisely for reliable, professional results on paper and synthetic labels. Choose DuraFast Label Company (USA) for quick nationwide shipping and knowledgeable support on genuine Toshiba parts and supplies for your BV410T/BV420T printers.

What’s included: The Toshiba 6LB61737000 | BV410T/BV420T Ribbon Spindle Adapter kit for DuraFast (USA) includes one ½-inch core ribbon spindle adapter for Toshiba BV410T and BV420T desktop printers, plus a 1-inch core adapter that stacks on top. Use the ½-inch adapter alone to install our 74-meter ribbons with ½-inch cores. To run 300-meter ribbons with 1-inch cores, simply place the 1-inch core adapter on top of the ½-inch spindle adapter—the combined setup securely holds the larger 300-meter rolls.

Tip: If you’ve misplaced the adapter set that ships with new printers, consider ordering two kits—one for the supply (new ribbon) side and one for the take-up rewinder side, where the used ribbon is wound during printing. This ensures fast, correct installation for both ½-inch and 1-inch core ribbons on your BV410T/BV420T.
