Rodstations offers a range of chimney coring balls which are used for ensuring chimneys are correctly constructed and for clearing the chimney of debris prior to installation of a flexible liner. The coring ball test is carried out by lowering a coring ball from the top of the chimney on a rope to the bottom of the flue or opening. When any obstructions are encountered the blockage should be removed and the repeated before a flexible chimney liner is installed.
Coring balls are constructed in solid steel and chrome plated with a smooth surface to pass easily through the chimney and to prevent rusting. Each ball includes 14 metres of heavy duty rope and a heavy duty lockable steel carbine.
