The Stanley Powerlock Top Reader Tape Measure is a professional pocket tape designed for accurate internal measurements in joinery, kitchen fitting and construction work. The innovative top-viewing window on the case displays measurements that automatically account for the case length, eliminating the need for manual calculations when measuring between walls, door frames or cabinet openings. Built for demanding trade environments, this tape measure features a Mylar-coated steel blade with metric graduations that offers up to 10 times more resistance to abrasion than standard lacquered blades. The robust construction ensures reliable performance on site, whilst the chrome-plated ABS plastic case provides both durability and a professional appearance. The tape is equipped with a 3-rivet, automatically adjustable tru-zero end hook for precise measurements, whether taking internal or external readings. A smooth quick-grab auto-locking mechanism allows single-handed operation, whilst the conventional steel belt clip ensures the tape stays secure on your tool belt or pocket throughout the working day.
