N3804AB3 ¼-inches Narrow Crown Stapler

Uses & Applications

Hitachi’s N3804AB3 narrow crown stapler is ideal for internal and external trim work, furniture assembly, cabinet and countertop work and other fine finish applications. It can be used in any application requiring superior holding strength in thin materials like soffit plywood, floor underlayment, cabinet backs, and countertop blanks. It’s 'one sweet stapler' as one of our end users put it.

Key Features and Benefits

Tool-free Depth Adjustment

The N3804AB3 offers tool-free depth adjustment that identically sets each staple to the desired depth into the material, for improved control and customization. Operating pressure ranges between 70-120 PSI and air consumption is .025ft3/cycle at 100 PSI.

Ergonomically Designed Flip Actuation Switch

Just move the switch from bump fire mode (hold the trigger and the stapler will drive a staple each time the nose touches a surface) to sequential fire mode (trigger must be depressed each time for more deliberate placement and a slower pace of work). Either way, its quick to make the switch as your application requires without any tooling to make the adjustment.

Lightweight and Well-balanced

Weighing in at only 2.3 lbs the N3804AB3 is extremely well-balanced. It fits comfortably and securely in hand thanks to the non-slip elastomer grip and trigger. The weight, balance and handling are just right for precision performance.

360 Degree Adjustable Exhaust Port

At the top of the stapler is the convenient 360° adjustable exhaust port. This can be spun around in any direction to ensure the air exhaust doesn’t blow in your face or near your work piece.

Warranty Info, What's in the Box, and Other Information

Warranty Information

Covered by Hitachi’s 5-year warranty.

What's in the Box?

The N3804AB3 stapler, a convenient case for easy transport and storage (885902), a no-mar tip (885969), hose fitting and safety glasses (875769).

More Information

Because it uses an 18 gauge narrow crown staple (only a ¼ of an inch across the top) and accepts staples lengths from ½-inches up to 1-1/2-inches – the staple doesn’t leave a huge mark – not much more than the top of a nail head if you were to use a nail in its place. It can also be used for tacking. Staples have excellent hold and are often times more cost effective for the application.

This stapler comes complete with a no-mar tip installed that can protect the work surface from marring. It also comes with the hose fitting already factory installed at the rear so it’s ready to go right out of the box. The fitting is angled upwards slightly to help keep the hose away from the user and off the work piece.

To load the high capacity solid steel magazine, simply draw the feeder back to lock, set staples over the exposed rail, then release the slider to securely hold the staples in place. The N3804AB3 can hold up to 100 staples for less frequent replenishment.

5 Stars
Flawless so far!
This is a great tool! I work in set construction for a community theater and I use this to attach 1/4" plywood to 2x2 frames to make walls and set pieces with 1 1/4" staples. I've used lots of air fastening tools and this is my favorite so far. I've shot more than 2,000 staples without any problems. I like the bump-fire option. The tool comfortable to use and has not misfired or jammed or anything but performed flawlessly.The magazine is easy and quick to load and it is easy to see how many staples are left. Mine came with a good case and pair of safety glasses. You'll also need oil.
