As the old saying goes, if it’s not broke then don’t fix it! That is very clearly the mantra that Staney are working to in the design of this product. The Powerlock is a model of Stanley tape measure that first hit the market way back in 1963, and has had very little, if any, amendments to the design ever since.
But, take a look at the built in features here, and it’s easy to see why they don’t need to make any changes. To start with we have a high quality chrome coated ABS case. It is in the iconic Stanley Powerlock shape, and provides a superb degree of high impact protection to the inner workings of the tool. The measuring tape itself is made of Mylar polyester for the ideal blend of flexibility with toughness.
The tape is backed up with a heat-treated spring to provide a longer lifespan from this key component. Finally the tape is crowned by a corrosion resistant Tru-Zero hook for accurate measurements.
All in all this is a high quality, if very simple, design.
