The Tape Tip a little plastic end that slips on the and of your tape measure to eliminate creative body contortions when measuring at an angle over long distances.
The flat “tip” of your tape inserts snuggly into a slot cut into the center of the ‘Tip, and tiny rare earth magnets lock it in place, also helping the ‘Tip to stick to metal surfaces for measuring. The ‘Tip’s arrow-like shape fits perfectly into corners (with a 1″ addition to measurement) or a lip on the bottom simulates use of the standard tape. You can also measure to the outside tip for a 1-1/2″ addition.
For $3 dollars, this looks worth a try if you measure corner-to-corner often.
