50ADLNS - 20 Gauge 1/2" Crown Long Nose Stapler

For heavy-duty projects requiring a longer reach, the GREX 50ADLNS fine wire stapler has a longer extended nose accessing more angles, tighter corners and reaching deeper into projects. Additionally, the 50ADLNS uses a heavier flat-wire staple with a wider crown and thicker gauge. The GREX 50AD fine wire stapler uses a 20-gauge 1/2" crown staple with lengths ranging from 3/16" to 5/8".

What's more, the 50ADLNS is available in four different designs: 50AD (industry standard), 50ADLNS (long nose - projects requiring a longer reach), 50AF (auto-fire - speed of production), and the 50AFLM (auto-fire long-magazine - less reloading for continuous speed of production).

GREX, demanded by Pros, for more than 20 years has helped professionals rise to the top of their trade. Now explore.
