Product Description

Product Description

The Construction Master is and has been the industry standard for carpenters and craftsmen for over 30 years. Its use is taught in apprenticeship and training programs at the high-school, college, union and industry level across our country and beyond. An entire generation of framers and stick-builders grew up using it and advising us on new capabilities they wanted built-in. Building materials and techniques have changed over the years but geometry and the need to work quickly and accurately with dimensions is as important and difficult as ever. Put the time-tested Construction Master Pro on your next project and you’ll be glad you did.

Amazon.com
