-Two of these are specialty models. One with a magnetic pad for attaching "tin caps"/"tin tabs" under the staple for greater surface area, and one for driving wide-crown roofing staples for shingles and roll-roofing.
Use these tools for quick application of housewrap, roofing felt, tar paper, fan-fold insulation, or any other textile.
Also, the tool of choice for attaching carpet padding.
Just whack the tool down like a hammer to drive--no squeezing required. If you lack the room to swing or want to be sure of your aim, you can put the nose down first and bump the stapler down with your hand like an office stapler.
