This 60-inch cross brace can add more stability to your work and protect it from wear over a long period of time. Cross braces are important and often necessary for large canvases. If you have a frame that is 36-inches or longer, you should consider installing at least one or two cross braces, and this cross brace is designed for use with stretcher bars. They are pre-notched to add a second cross brace without having to notch them, and they are very easy to work with and install. The bracket set is included for free, and this is a single 60-inch cross brace.
