The spring mandrel (mousetrap style) EX75R is ergonomically correct because the weight of the tape roll is above the hand, not behind it. Designed for 3 inch wide carton sealing tape, this economical, lightweight dispenser has a natural rubber roller, utilizes a spring loaded tape arm to hold the roll of tape in place rather than a tape mandrel, and has a comfortable rubberized grip. Perfect for all carton sealing applications.
