Bostitch's P51-10B Pneumatic Stapling Pliers have a powerful shuttle blade that provides compression prior and during the stapling operation, giving a strong and tight closure without breaking the corrugated surface. A high throat area allows flexibility of staple placement and helps limit interference from obstacles such as box flanges. The P51-10B is ideal for fastening corrugated containers, vegetable tray boxes, end caps, container inserts and more.

Better than ever!!!
The latest design of this stapler from Stanley is by far the best out there. They have strengthened the anvil portion as well as the cast housing.

Excellent Tool -- Perfect for our needs.
The anvil stapler is used to fasten plastic end caps into heavy cardboard tubes that contain aircraft tubing to be shipped overseas. The 1/2" staples are clinched over perfectly, and it makes a very strong end closing. Very satisfied and highly recommend the Bostitch Anvil Stapler.

Great Stapler at a Great Price
This stapler is replacing it's predecessor Bostitch P50-10B that lasted more than 25 years until it was worn out. I hope this one is a good, time will tell.

The website says that the operating pressure is 70-100 PSI, but the manual says 30-55 p.s.i., do not exceed 55 p.s.i.

So what is the correct operating pressure?
