The Stanley 50m Fibreglass Tape Measure features a durable closed case with a high-impact ABS housing and rewind lever for easy storage and protection on site. The blade is constructed from parallel fibreglass threads with a washable PVC coating, reducing elasticity and improving measuring accuracy with 2mm graduated markings. Corrosion-resistant, UV-protected, and non-conductive, this tape measure is ideal for electricians, construction workers, and site engineers requiring reliable long-distance measurements in harsh conditions.
