The Company’s Pipestoppers® department, manufactures cylindrical and spherical inflatable stoppers to compliment its range of round mechanical pipe plugs.
We were contacted recently to supply some Square stoppers urgently to a renovation company, moving an old historic Chimney from inside a museum.
It was necessary to place 15” Square Stoppers at the top and bottom of the chimney to prevent items being dropped through the chimney and injuring people or damaging property at the other end. 
After successful tests, HFT® Pipestoppers® supplied a number of square stoppers form stock for the operator to successfully complete the removal.
Other rectangular section items have been provided to Central Heating Companies for large installations.
