After intensive research selected and confirmed. Why? - The execution of a superior quality, the deflection or the game's elements low. - The pulling apart each telescopic ladder is relatively simple, not the way back: The Trebs ladder glides through the air content of the pipes is attenuated rapidly, but smoothly and without impact to unlocking a stage together. This also works when you open one of the lower unlocking and still carries the lower sliding element several steps above him. (Important because a standing 3.20 Head of course can not be pushed together "from above" without lie it.) - The spacers renounce fragile folding mechanisms and are designed as the closing motion of additional damping, relatively resistant rubber elements. Very good solution. - Weighed 10.7 kg must be worn well with the very comfortable foam rubber grip: the circuit is short enough above the handle, so that they also fit well under the arm - With less than 90 cm retracted length she really fits in most cars: Cheaper Prodjkte are sometimes pushed still for more than 1m: this is a measure that would in many vehicles exceeds the trunk width and force the folding down the rear bench in smaller and medium-sized vehicles as only larger estate cars have such a long boot floor. ... That is not very convincing and resolved outstanding in this ladder. - With all the mentioned advantages still a very acceptable price.
