Dönges Sewer Quick Sealing Gully Stop, Complete set

The Gully-Stop is the ideal quick sealer for emergencies. The Gully-Stop, which is filled with a mixture of water and a special antifreeze (with higher specific gravity than water) and is made from a mineral oil resistant, coated tarpaulin material, is secured to the wall in the vicinity of gully inlets using a special wall bracket and is simply
taken from the wall bracket in an emergency and placed onto the gully.

The heavy intrinsic weight provides a reliable seal and prevents the Gully-Stop from floating.
