The IBS-4 is used mainly with existing pools when the width of the pool tapers off towards the bottom.

A separate pit for the roller system is not necessary. In combination with a tubular motor, no motor pit is necessary either.

The roller system is mounted directly below the surface of the water, for new pools or for subsequent fitting.
