wolfcraft 1 internal dimension adapter for folding rulers

Where your folding rule reaches its limits, this practical accessory from the Pimp my folding rule series creates new possibilities. The internal dimension adapter was specially developed for measuring internal dimensions that are difficult to reach. It fits on any standard folding rule and provides you with exact measurement data even in hard-to-reach places. Simply slide it onto the folding rule and guide it up to the measuring limit as an extension of the last folding rule element that still fits. Now fix the position with the locking screw. The protrusion of the internal dimension adapter now marks the correct internal dimension - simply unfold the next element of your folding rule and read off the number. Ideal for installation work, such as shelves and cupboard bases, drawers and much more.
