Hog Ring Guns
The Bostitch SC743-B, Salco SC743-16, Salco SC7-15, and SC7C-15G Meite are all very durable pneumatic hog-ring sealers.
In our experience, the stainless steel hog rings are best for the surface shell framing, and the regular galvanized hog rings are a great hog ring option for the basic shell.
