They must bo used in pairs and are specially designed to meet individual applications. Available in both non-equalising and self* equalising types, cither flanged or welded ends. The above designs suggest the versatility of the Rodger corrugated type of expan sion joint.. . (m joint that requires no maintenance. There ore others equally useful.
