PS3425 Lufkin Pro Series Tape Measure Review
The Lufkin Pro Series tape measure has a toggle-locking mechanism and includes both English and metric scales
This device locks the tape with a toggle button, which we found to be the easiest type of locking mechanism to use. The hook on the end of the tape is fastened by four rivets, rather than the three that are found on most other tape measures. The tape has both English and metric scales.
