General Purpose Duct Tape 3903
This 3M duct tape uses a vinyl-coated cloth backing with a rubber adhesive for everyday assembly, maintenance and repair tasks. The roll measures 4 inches wide by 50 yards long and has a 6.5 mil thickness. It is rated for indoor use only.
Temperature Range 40 to 200 Degrees F
The tape performs continuously between 40 and 200 degrees Fahrenheit, so it will not suit environments that exceed those limits. Adhesion to steel is rated at 15.4 ounces per inch, which determines holding power on metal surfaces. Buyers needing outdoor durability or higher temperature resistance should choose a different product.
Embossed Vinyl Construction
The embossed vinyl backing conforms to irregular surfaces and tears cleanly by hand without tools. No additional accessories or software are included with the roll. The tape is restricted from sale in certain states, so availability depends on local regulations.

Questions about this item
How does the 6.5 mil thickness perform when the tape is applied in a real installation?
The 6.5 mil vinyl-coated cloth backing provides a balance of conformability and tear resistance for general-purpose bundling, sealing and repair tasks on job sites.
What does the rubber adhesive's 15.4 oz/in adhesion to steel mean for the temperature range of 40 to 200 degrees F?
The rubber adhesive maintains its 15.4 oz/in bond to steel across the 40 to 200 degrees F performance window, so the tape stays secure in both cool and hot indoor environments.
Will the 4-inch by 50-yard continuous roll fit on a standard duct-tape dispenser or tool belt?
The 4-inch width matches common heavy-duty dispenser jaws, and the 50-yard roll diameter fits most tool-belt loops and benchtop holders designed for standard duct-tape cores.
