++++++ Specification required for an order ++++++
The specification of the desired useful length is required for an order.
The useful length usually corresponds to the length of the longest compartment to be filled.
The retracted length is approx. 40cm more than the useful length divided by 2.
Example: Compartment length: 7.400mm --- Useful length 7.400mm
The retracted length is then: 7,400 : 2 + 400mm approx. 4,100mm

+++++++++++++++++++++++++++++++++++++++++++++++++++++
Usable length L ______mm required for the order
Example:
Effective length longest fillable element: approx. 7,000mm
Total length when extended: approx. 7,400mm
Total length with telescope retracted: 3500 + approx. 400 approx. 3,900mm
