Web Bracing
CLB: Continous lateral bracing is 1x4 or 2x4 materials mailed to the narrow side of a web. CLB braces must be fastened across a minimum of 3 trusses. If you don't have a run of at least 3 trusses, you must use another type of brace.
The CLB brace show below is in blue, with diagonal bracing to "brace the brace" shown in red. The truss drawing will show a brace on the web, and also have a note specifying the brace, as shown to the right.
