Senco 16/17 Gauge Construction Stapler (SNS200XP)

For high production stapling, you'll be hard pressed to find a stapler that offers better performance and features than the SNS200XP.


Senco 16/17 Gauge Construction Stapler (SNS200XP)

Staples are a good choice in many situations where you would normally use a fastener up to about 2" in length. Applications include sheathing, sub-flooring, roof decking, fascia and soffits, and cabinet assembly. They're worth considering for at least three reasons — they have excellent holding power, they're quick to install, and they're very cost effective.
The Senco 16/17 Gauge Construction Stapler (SNS200XP) is primarily geared to carpenters, renovators, cabinetmakers, and other tradespeople doing production work, rather than DIYers or craftspeople looking to use a stapler for more light- duty, intermittent work.
The SNS200XP operates at between 70 and 120 PSI, and consumes just under 4 cubic feet of air per minute. It takes 16 and 17 gauge 7/16" wide crown staples in 1" to 2" lengths.
Excellent balance and weight
At just over 5 pounds the SNS200XP is about 40% lighter than a framing nailer, and coupled with its compact size — 3-1/2" x 11" x 15" — it's quite well balanced, even though much of the weight is located at the front, at the cylinder head. The rubber over grip provides some cushioning, which makes the stapler less fatiguing to use over long periods of time.
Cast aluminum cylinder head and cap
I was glad to see that there is little plastic used on the SNS200XP, particularly in critical areas that are most likely to receive a lot of wear and tear. The cylinder head and cap are made of cast aluminum — lighter than steel yet strong and durable enough for rigorous job-site use. Thought quite wide at the top, the head tapers towards the firing pin, and provides a surprisingly good line-of-sight, making it that much easier to place staples right where you want them to go. I found this very convenient, especially when working into corners or tight up against vertical surfaces.
Exhaust air is deflected downwards out of the front of the stapler, which keeps the exhaust from blowing up into your face. The fact that the deflector isn't adjustable didn't bother me. It's a feature I find more useful on pin nailers as it eliminates the chance of oil droplets contacting a work surface.

Feeder mechanism
Steel ribbon spring
The feeder mechanism and magazine are made of a combination of steel and aluminum. The steel feeder (A) has a plastic grip for pulling the feeder back along the magazine. A steel ribbon spring (B), wound up inside the feeder, and attached to the front of the magazine, forces the staples tightly up against the front plate, ensuring optimal contact with the firing pin. Which might help account for the fact that I haven't experienced a single misfire while using the SNS200XP.
The outer rail (C) of the magazine is made of steel. The rest of the drive track is made of aluminum. The lower magazine assembly (D) is milled from a 5/16" thick piece of aluminum for durability and long life. The series of six oval cutouts likely reduces overall weight.  
The open face design of the magazine makes it easier to install and monitor staples, which you'll need to do, as the SNS200XP doesn't have a dry-fire lockout feature. I'd much rather have the lockout feature, which prevents the drive pin from firing when there aren't any nails in the magazine — rather than having to visually monitor the magazine.

Feeder release lock
Outer rail moves back for easy staple installation
The SNS200XP has a nice feature that makes loading and unloading staples super fast and easy. When the feeder mechanism is pulled all the way backwards it locks into place. As the feeder is moved backwards, the outer rail tilts away from the mounting rail so you can easily slip the staples over the rail. It works like a charm.
Once the staples are loaded, all you need to do is smack the back of the feeder mechanism with the palm of your hand — the feeder will spring forward, applying pressure against the staples, snugging them up against the front plate. This speeds up reloading in high production environments.
160 clip capacity
The larger the magazine capacity the better — you'll spend more time stapling and less time loading. The SNS200XP has a generous 160 clip capacity. Unfortunately, all the staples I buy come in 70-staple clips, which means you have to break up a clip to fully load the magazine.

Magazine release lever
Magazine moves backwards for easy jam clearing
I was impressed with the innovative jam clearing mechanism on the SNS200XP, but the darn thing never jammed, no matter how hard I tried to muck it up. But, if it does happen to jam, removing staples from the nosepiece will be a piece of cake. 
On the back end of the magazine carriage is a release lever. Flip it open and the magazine moves backward, about 3/8", providing enough space to pry out an errant staple with needle nose pliers. Once the jam is cleared, a smart rap to the end of the magazine carriage closes the release lever and firmly locks the magazine back in place. You're unlikely to find a more effective jam clearing system than this one.
Trigger and depth of drive control wheel
The SN200XP has a generous sized high impact plastic trigger. It comes with a contact actuation (dual action or bump fire) trigger. The trigger can be used in two modes. In trigger fire mode you first depress the nose against the work piece, and then pull the trigger. In contact fire (or) bottom fire mode the process is reversed — first depress the trigger, and then press (or bump) the nose against the work piece. Each time you bump the nose while continuing to hold the trigger a staple is fired. I find this mode to be, by far, the quickest and easiest way to place staples. 
However, you can obtain a single sequential (or restrictive) trigger — where you need to depress the nose and then press the trigger each time you want to fire a staple — free of charge from Senco.
As on most nailers and staplers, the SNS200XP features a tool-free adjustable depth of drive wheel located just below the trigger. While you many not need to adjust the drive depth as frequently as you would on a finish or framing nailer, it's still a useful feature, particularly when you're working with soft or thin material. The control wheel is easy enough to adjust, but I found it a tad too recessed to use effectively when wearing gloves. 
Long, narrow nose for easy staple placement
The long, narrow nose, coupled with the tapered design of the head, makes it easy to place staples just where you want them to go. The white arrow head on the tip of the nose, which points to the center of the staple crown, helps you to more quickly position the stapler.
A durable, hard working stapler that drives well in any material
The SNS200XP doesn't come with a 3/8" NTP air fitting, which isn't a big deal. However, neither does it come with a storage bag or case, which I found to be a bit disappointing, as I like to keep my tools protected and secure when not in use. Besides, tool bags are also handy for storing accessories like lubricating oil, fasteners, eye protection, gloves, and the like. 
Still, I'm very impressed with the SNS200XP. I had no trouble seating 2" staples in OSB, MDF, plywood, and solid wood. Not a single misfire the whole time I used the stapler, and every staple perfectly seated. Though the legs on a 16-gauge staple are narrow — 3/16" diameter — they hold very well because of the wide bearing surface (5/16") provided by the crown. The crown delivers significantly more compressive pressure than the small head of a 16-gauge finish nail. 
Senco claims that the SNS200XP will cycle 10 times per second - that's considerably faster than I'm able to use the stapler. But once you get into a groove, it's surprising how fast, and smoothly, you can sink staples.
Out on the east coast I pay approximately $48 for a box of 4,000 2-1/2" 16 gauge angled nails. Compare this to $60 for a box of 10,000 7/16" 2" 16-gauge staples. That's roughly half the price, a significant cost savings in anyone's book. Stainless steel staples are also less expensive than stainless finish nails.
The SNS200XP has a lot going for it — excellent fit and finish; good weight and balance; quick staple loading; easy jam clearing; and, over the six week period I tried the stapler, not a single misfire. Coupled with a 5-year warranty, the $279 price tag doesn't look like overkill. You can certainly find staplers that cost less than the SNS200XP, but for high production stapling, you'll be hard pressed to find one that offers better performance and features.
