Since 1947 Johnson Level & Tool has been developing solutions to help professional tradesmen improve their work. The versatility and durability of Johnson's Johnny Square®" came to us from professional master carpenter Johnny Wong, an accomplished homebuilder with more than twenty-five years experience in the trades. Johnny's crews were never satisfied with their rafter squares' inability to allow for fast and accurate measurements for rip cuts. Anyone looking to make fast accurate 45° and 90° markings will appreciate this tool.
