Underfloor systems

R1 First locking ladder position

The first usable locking ladder position is the basis for the minimum floor structure height during device installation. In this position, socket use with angular connectors is possible when the device installation unit is closed.

R2 Lowest locking ladder position

The lowest locking ladder position relates to the maximum possible lowering of the universal support, without additional components such as the locking ladder extension.

R3 Lowest locking ladder position with
locking ladder extension

If the locking ladder extension is used, the lowering range of the universal support increases by 26 mm. This makes four additional locking ladder positions available.
