Stopped Working
I purchased this tool several months ago for home use, repairing small holes in my home roof felt. Have used it several times and now it has stopped working. I assume it is a jammed staple in the head so I am attempting to find an owner's manual online, no luck yet.

Best Hammer Stapler I Have Ever Used
I use this item for tacking down the paper under hardwood flooring. I have used probably a half dozen hammer tackers before, but this one blows the rest out of the park. Weighted just right. comfortable grip. Just an overall great stapler. I have had zero problems with it.

Is this an outward clench or inward clench tacker
Mike on Nov 5, 2015
BEST ANSWER: This item does not work by clenching the grip. You hammer the head into the intended surface to dispense the tacks.
