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. With more than three years of
field testing, the “Johnny Square®” helps
professionals like Johnny do more work
in less time.
Johnson®—TOUGH, RELIABLE, ACCURATE
