Professional Precision Fastening: Spotnails WS4840 18-Gauge Narrow Crown Stapler

The Spotnails WS4840 is a high-performance pneumatic 1/4" narrow crown stapler designed to meet the rigorous demands of professional cabinet makers, trim carpenters, and flooring installers. Engineered as a true production workhorse, this tool excels at fastening floor underlayment, assembling fine cabinetry, and securing door or window trim with seamless accuracy. At a lightweight 3.56 lbs, it significantly reduces user fatigue during extended use, while the high-capacity 168-staple magazine ensures you spend more time fastening and less time reloading on the jobsite.

Versatility and control are at the forefront of the WS4840 design, featuring a selectable trigger system that allows you to switch between precision sequential firing and high-speed bump fire modes. The adjustable depth-of-drive allows you to easily dial in the perfect staple depth for a flush finish across varying material densities, from softwoods to dense underlayment. With a quick-clear nose to minimize downtime from rare jams and a 360-degree adjustable exhaust to keep air and debris away from your face, this 18-gauge stapler provides the reliability and professional features required for a perfect finish every time.

Key Features

  • Selectable Trigger System: Includes both restrictive (sequential) and bump fire triggers to prioritize either surgical precision or maximum production speed.
  • Adjustable Depth Control: Simplifies the process of setting staples to a perfect flush finish in diverse wood and composite materials.
  • Quick Clear Nose: Designed for rapid access to the drive channel to clear jams instantly and reduce project downtime.
  • 360° Adjustable Exhaust: Allows the user to direct air and oil spray away from their body and the work surface.
  • Broad Staple Compatibility: Operates efficiently with standard 18-gauge 1/4" crown staples, including Senco L and Duo-Fast 1800 series.
  • High-Capacity Magazine: Holds up to 168 staples to streamline high-volume production tasks.

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!
