50AFLM - 20 Ga 1/2" Crown Auto-Fire long-magazine Stapler

Doubling staple capacity for today's fast paced production needs, the GREX 50AFLM auto-fire long-magazine stapler includes auto-fire and a longer magazine. The 50AFLM magazine holds two full strips of staples.

GREX patent pending auto-fire speed dial allows the GREX 50AFLM fine wire stapler to shoot one staple or rapid-fire several staples per single trigger pull. Turning the auto-fire speed dial counter-clockwise (towards A - Automatic) increases shots per minute and turning the auto-fire speed dial clockwise (towards S - Single) reduces shots per minute.

For projects requiring a heavier flat-wire staple with a wider crown and thicker gauge, the GREX 50AFLM fine wire stapler uses a 20-gauge 1/2" crown staple with lengths ranging from 3/16" to 5/8".

What's more, the 50AFLM 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.
