A bracket is disclosed for attaching an oxidation test fixture or the like to a pair of parallel boiler tubes. The bracket includes a support bar, a pair of jaws the remote faces of which each has a configuration which conforms generally with the adjacent portion of the outer periphery of the associated boiler tube, and shaft means with oppositely threaded ends connecting the pair of jaws. The bracket is placed between the boiler tubes and the threaded shaft is turned to simultaneously displace the jaws apart into tight engagement with the tubes. A test rack designed to hold various metal samples is then attached to the support bar.
