Lots of expensive stuff here. A pneumatic rivet squeezer with several interchangeable yokes. The squeezer has an adjustable set on the plunger. A longeron yoke is on the squeezer with some quick release pins. I also have a standard 3 inch yoke and a 4 inch "no hole" yoke. The no hole yoke allows you to get into tighter places. The white plastic blocks hold a variety of dimple dies and rivet sets for flush and standard rivets.
