Diagonal Brace Ends for Single Rails

Use diagonal brace ends to make a brace of any length—a connecting rail (sold separately) between the brace ends is required. To install, use a tap (sold separately) to create a threaded hole, then fasten the brace end to a connecting rail using the included hardware. Brace ends with no required tap thread size include thread-forming screws.
