Outside Vent Explained

The outside vented version is designed for installations where the cassette bay has a vent aperture through the vehicle floor. This allows waste gases to vent externally — keeping odours out of the habitation area. Check your vehicles cassette bay configuration before ordering to confirm whether you have an outside or inside vented installation.

Whats Included

This replacement cassette comes complete with the sliding blade cover, moulded carry handle, and rolling wheels — making emptying and re-installation as straightforward as with the original unit.
