The In-Sizer Measuring Tape tool consist of a case with a 5-inch-long base containing a retractable measuring tape. The tape’s measurement starts at 5 inches with continued markings (5,6,7, etc.)
The case is equipped with a locking mechanism to lock the retracted tape in place for ease of taking the inside measurements. The length of the 5-inch-long base and the length of the retractable tape locked in place by using the locking mechanism give you, in sum, the total length between two walls. The reading point at which the measurement is read is located at the point where the retracted tape enters the case.
No need to do any math, to bend the tape, or to use any hacks to get a 100% accurate measurements every single time.
In-Sizer Measuring Tape has two scales: an ordinary and unique for inside measurements and can be either imperial or metric system.
