Komelon SL2830 30-Feet x 1-Inch Self Lock Tape Measure
The 30-foot Self lock has a 1-inch nylon coated blade and features Komelon's patented self locking feature.  When you pull the blade out it locks itself, to retract the blade you use the easy to work thumb push button release to control the rate of return.  The case color is Hi Viz green and it is compact for easy handling.  The Self lock series is Komelon's #1 selling line of tapes and once you use this tape you will agree this is how all tapes should work.
