JUMBRELLA ”4-step reduction gear”
This figurative notion refers to the new, sensationally facilitated first-time unfolding, in particular first-time tensioning procedure required for all factory-new rectangular JUMBRELLA models including, however, the special 5x5m square NNK model: It’s the invention and the introduction of the »dual staggered-catch tension rod« on September 23, 2011 that enabled us to split the operator’s total expenditure of physical force required up into four part steps at each approx. 25% of the total mechanical resistance generated by the said factory-new standard production models (see INSTRUCTIONS # 111027).
