March 11, 2013 – Stanley Tools is celebrating 50 years since the launch of the PowerLock tape measure line. To commemorate, Stanley is releasing a limited edition series of five tape measures featuring designs dedicated to highlights in the PowerLock tape measure’s history.
The tributes include a replication of the original “Life Guard Yellow” Powerlock design, and a testament to its inclusion in the Apollo 11 lunar landing gear. A new tape measure will be available every three months, and the fifth one will be free with purchase of the first four.
The D-shaped PowerLock design was introduced in 1963 with the world’s first coilable spring and sliding lock, says Stanley. The 50th anniversary coincides with the company’s milestone of 170 years, as it was originally founded in 1843.
