## Description

Radiator removal to many can prove to be a tricky task. It is well known that many of us have experienced dropping water or sludge from a radiator during the removal process onto floor coverings leaving the expense of a cleaning bill or worse still having to replace the flooring altogether.

It allows you to cap off the radiator as a fully sealed unit without the need for draining down and also makes it safer to carry the radiator from A to B.
