Meet The Inventor Series: John English - The Pivot Square®

An architect & licensed builder, John English invented the Pivot Square® to solve a common problem in the construction and architectural fields: determining actual roof slopes or pitches of existing houses.

The Pivot Square®, which can determine existing slopes, pitches and angles quickly and accurately, gives tradesmen a multi-purpose tool that combines the functions of many existing tools into a single, easy-to-use device.

Because of his unusual dual role as a registered architect and a licensed builder, John had the unique perspective to combine the similar functions of a drafting tool and a carpenter’s square. Today, his legacy lives on among skilled tradesmen and average homeowners alike; John English, passed away in 2009. C.H. Hanson® continues to pay royalties to his widow.
