In the Rucksack shaft

As a rule this solution should be planned when building the pool. One advantage of this solution is that the size of the pool can be used to an optimum.

The solution with a rucksack shaft is particularly interesting when planned early.
To do this, a recess is created in the pool wall, this has inclined slope to the normal pool wall upwards to the water surface. The rucksack shaft can be cladded apart from an outlet gap for the cover; this gives it a closed, fully integrated appearance.
No grid is required on the pool wall and the whole area of the pool can be used.
Certainly one of the most inconspicuous roll-up devices.
