The best framing square in the universe
What if one tool could change the way you build—forever?
The Chappell Universal Square isn’t just another framing square. It’s a breakthrough approach to laying out roof systems, designed to eliminate confusion, unlock the secrets of compound roof framing, and give you the confidence to tackle even the most challenging roof framing projects—all with only a pencil and scrap piece of wood. No calculator—No batteries required. The Chappell Square is no gizmo either. It represents a lifetime of building knowledge and experience deeply etched into the patented tables on a durable stainless steel square. This is more than durability. More than precision. It’s clarity. It’s speed. It’s knowledge. It’s control of your own building future.
From your first frame to your most complex roof layout, the Chappell Square puts expert-level knowledge right in the palm of your hands—so you can build smarter, faster, and with absolute confidence. And here’s the best part— you take zero risk. If it doesn’t live up to its claim as The Best Square in the Universe, send it back for a full refund. No hassle. No questions. Once you use it, you won’t want to work without it. The Chappell Universal Square isn’t just another framing square—it’s a game changer.
So go ahead…Let your imagination run wild…and your talents soar.

There is no excuse not to buy one. It’s like comparing using a handsaw to a circular saw. Compare this to a normal framing square…there is no comparison. It’s that simple!
