Height Adjustability of Vari-Level Extensions

This information is provided as a supplement to the height adjustability information provided in our 'Floor Gullies and Access Covers' technical manual and other literature.

When used with certain gully bodies, our U1 series extensions must be cut to length on site in order to achieve the minimum height gained figures quoted in our literature. This supplement provides figures for the minimum height that can be achieved without cutting the extensions for the affected gully bodies.
