The best framing square available

O
ur mission when we set out to develop this square was to make a solid, durable, and accurate square that would provide long-term value to the carpenter not only through many years of use, but also through expanded creativity. It is our belief that we hit the mark, and believe you will agree once you’ve used the Chappell Universal Square. We will even back this up with a straightforward guarantee. If you feel that it does not live up to the claim as the Best Square in the Universe, simply send it back and we’ll send you a complete refund. Most of all, I hope the new square helps you to become more creative. —Steve Chappell

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!
