If you're doing a lot of hog ringing – think building animal cages, fixing sofa springs, re-upholstering car seats, or setting up fencing – this pneumatic gun is a massive time and energy saver. It's a standard 15-gauge tool that uses 3/4-inch crown staples (galvanized or stainless steel). Instead of squeezing pliers all day, you just connect it to an air compressor, load the staple coil, and pull the trigger. Bam – staple closed in about a quarter of a second. Your hands won't ache after hundreds of rings. It's built with a lightweight aluminum body so it's not tiring to hold, and the jaws are heat-treated to be super hard and durable. The trigger and oversized rubber grip are designed for comfort during long use. It automatically feeds the staples, so you just keep working. Comes with the gun itself, a couple starter strips of staples, a tool kit for maintenance, some spare seals, and the manual. Woodpecker is known for good pneumatic tools, and this C-7CA is a solid, reliable workhorse for pros or serious DIYers.
