Where your measuring stick reaches its limits, this practical accessory from the Pimp-my-Zollstock series creates new possibilities. The interior measurement adapter has been specifically designed for measuring hard-to-reach interior dimensions. It fits on any standard measuring stick and provides you with precise measurement data even in difficult-to-access areas. Simply slide it onto the measuring stick and extend it from the last fitting element to the measurement limit. Now, secure the position with the locking screw. The extension of the interior measurement adapter now marks the correct interior measurement – just unfold the next element of your measuring stick and read the number. Ideal for installation work, such as shelves, cabinet bottoms, drawers, and much more.
