Word of warning to those buying a stapler..make sure the staples are standard size and easy to find.(get at least two suppliers) I initially spent $200 or so on a Sears brand wide-crown pneumatic stapler,( thinking a large retialer would be a safe bet) and was told the staples are availble anywhere..a standard. 6 months later Sears stopped carring the product and the staples and when I found other brands they would not fit the Sears gun. Returned to Sears and was told sorry they no longer carry the staples..after talkng to the manger I got no further. I now have a Sears brand paper weight.
Of course I ran out just as I had an order for 75 canvas wraps come in.....not doing those by hand!
I have tried the narrow crown staples, in another gun, and found them to be inadequate.
I bought an pneumatic upholstery stapler, Performance Plus by King Canada, at a local contractor supply store. It has standard wide crown staples and seems to work fine..much smaller and lighter than the other pnuematic guns I have. I bought 40 thousand staples to make sure I had a supply for a while...and made sure they kept them in stock.
I have had the gun for a year or so now and have been quite happy with it..not as many adjustments as other for depth etc but works great.
Hope this helps out.
