ABSTRACT:
A tube shield and a method of providing shielding for tubes. The tube shield is provided in a cane or J-configuration, including an upper hook portion and a sheet portion, and a U or drape configuration, including an upper hook portion and a pair of spaced sheet portions extending downwardly from the hook portion in a parallel spaced relation. In both shields, spacer means are provided in the form of embossed protuberances of generally hemispherical configuration extending outwardly from the general plane of the sheet portions at spaced locations on the sheet portions. In the assembled relation of the shields in a tube installation, cane shields are hooked over the outboard rows of tubes and drape shields are hooked over the inboard rows of tube with the protuberances on the sheet portions of the tubes maintaining the sheet portions of the adjacent shields in positive spaced relation.
