The advent 2 in 1 double sided gap tape measure is a specialist measuring tool designed for accurate internal and external measurements in bricklaying and general trade applications. This versatile tape measure features a double sided, non reflective steel blade with both metric and imperial graduations, making it ideal for contractors working across different measurement systems. The unique dual reading system eliminates the need for mental calculations when measuring internal spaces. Standard measurements appear on the top of the blade for conventional use, whilst the reverse side displays markings that automatically account for the tape case dimensions. When measuring gaps, recesses or internal spaces, simply butt the case against the end wall and read the accurate measurement directly from the reverse blade. The 5 metre 16 foot tape is housed in an ergonomically designed abs case with a moulded rubber grip, providing enhanced comfort during extended use. The 25mm wide blade offers improved rigidity and visibility, particularly useful for overhead measurements or when working at distance. This gap tape measure is particularly suited to bricklayers, plasterers and shopfitters who regularly need to measure internal dimensions with precision.
