Package includes five heatshrink tube label tapes compatible with HSe621 HS621 HSe621 HS621 label makers. Color is black text on yellow tape. Each tape measures 3/8 inch 8.8 mm flattened width by 4.92 feet 1.5 m length. The flattened width measurement applies to the label printer, not the wire. After shrinking the tube fits cables with diameters from 2.6 mm to 5.1 mm. Key benefits Clear and durable identification: Print legible text directly on the tubing with any compatible label maker for professional cable identification. Secure, permanent fit: 2 to 1 shrink ratio ensures the tube snugly conforms to the cable when heated so labels do not curl or fall off. Fast, lowtemperature shrinking: Tubing shrinks quickly and evenly with a heat gun or similar heat source for efficient installation. Durable material performance: Flexible, insulating tubing resists moisture, oil, grease, chemicals and UV exposure to maintain longlasting markings and protection.
