Kendo 8m Retractable Measuring tape
This 8-meter tape from Kendo is a reassuringly solid unit, feeling hefty in the palm when you hold it. There are two buttons within easy reach of your fingers.
The standard lock switch holds the tape in place. Easy to lock, and when you release the tape retracts.
The second button is just underneath. Hold this with your thumb to lock the tape in place, then release to retract it. Convenient when you measure, want a quick look and then move on.
