Duct Tape 26 inches x 2 inches (66 x 5 cm), rolled around plastic mandrel, repairs, first aid, the ultimate repair and improvisation component, uses limited only by your imagination It’s been said that if you can’t fix it with duct tape, it isn’t really broken. Duct tape is one of the most versatile items you can have on hand in many emergencies. It’s much more useful than the 3/4-inch (19 mm) electrical tape used to seal some other kits. And, unlike other pocket kits that include only 3.5 or 12 inches of duct tape, we include over two feet. That’s enough to be really useful, as opposed to just being able to patch a small hole or mend a small tear. This is the same small-diameter roll included in Adventure Medical Kits’ GearAid "Go! Repair" kit and it has proven itself up to the task in the field for short-term repairs and resistant to degradation in storage from extremes of temperature (as much as any duct tape is, at any rate; we can't work miracles). AMK assembles these rolls themselves from bulk packaged large rolls of tape. It is wound around a 1/4-inch diameter plastic tube. The grade of tape was selected as a compromise between a heavy industrial grade or mil-spec grade tape that is much thicker and would have allowed less than half as much in the same size roll and the very lightweight consumer grades that do not have as much tensile strength or as strong an adhesive.
