Porter-Cable US58 1/4-Inch to 5/8-Inch 22-Gauge C-Crown Upholstery Stapler
Review by w00dw0rker : Stapler is fine, but where is the hard case?

This review is going to be short. As expected from PC, this is a nice tool that does exactly what it is supposed to and advertised. I had no problems from that aspect. So, why not a top score? Well, if there is any thing that is harmful to a pneumatic tool, that must be the exposure of the tool to saw dust and other particles that are flying around in the air. Saw dust and particle production is at it's top when the nailer is not being used. Because, I am usually sawing, routing, sanding, etc. I'd like to keep my tools in their boxes so that saw dust can not get to them. I have several PC nailers and this is the first one that came without a case. I hope that folks from PC read this review and the three stars catches their attention. I am willing to pay the extra few $ and get the case. It helps keeping me organized and my tools nice and clean. I think many would agree with me on this!

Review by David P : Great little stapler but missing usual PC extras

I received my PC stapler a few days ago and have used it for some small tasks. Overall it works very well, adjusting the regulator pressure across the range of 100 to 80 nicely modified the depth/force of the staples being driven. The stapler comes with just a cardboard box and bottle of oil - the usual PC hard case and starter set of nails/staples was missing, which is why I only give it four stars. Staples are only available online (galvanized) or at upholstery stores (liquor finish) - neither Lowes nor Home Depot carry them.

Overall this stapler is a very nice device and I would have given it a 5 except for the missing extras.

Review by "slp13" : Great stapler, but a word of caution

Light and effective. It does its job as well as I could have hoped. Not a single jam that was not obviously my fault. I have spent several times the cost of this tool looking for a stapler that would do what this one does as well as it does. Why the enthusiasm? Well, most staplers not meant for construction site abuse are not very good. This one is.A word of caution. This is not, nor was it ever intended to be, a construction stapler. The staples it is designed to use are not big enough nor thick enough to be of much use for construction site purposes. This is a professional grade upholstery stapler.

Review by SJK : Porter-Cable US58 Upholstery Stapler

Nice stapler. Very easy to use, compact and heavy duty. No depth adjustment collar or thumbscrew to fiddle with, just change your air pressure setting and keep on going. Securing thick, heavyweight upholstery material onto hard wood furniture frames repetitively is a breeze.
Assuming that you already own a small portable compressor, and don't mind dealing with the air hose, I personally feel that the US58 is a better and much less expensive alternative to a true professional grade electric upholstery stapler and with only minimal care, will probably last much longer.
For some reason, there is no carrying case included with this stapler. I was able to purchase one though, through the Dewalt/Porter-Cable service net website for about eleven dollars plus freight [Part #891602]. It is just a small case similar to the one that came with my PIN-100 pinner, but it definitely makes it much easier to transport and store this tool along with maybe a dozen or so assorted sizes of staple strips.
The B&C Eagle staples that are sold here on Amazon are good quality, but I find that the Porter-Cable brand staples sold elsewhere are every bit as good and are also less than half the price for the same ten thousand count boxes.
Overall, I really like this PC stapler and have no problem recommending it to anyone who is looking to purchase this type of tool.
