The 8 in. Speedlite® Square is formed from lightweight, high-impact structural composite, and is available in matte gray, high-visibility yellow and high-visibility orange. It’s basically the same as the one and only Speed® Square but is also great for use with siding and other delicate materials, since it won’t mar soft finishes. Plus, its 8 in. size means it’s ideal for marking cuts in 8 in. siding. Look for the Diamond®.
