This pop rivets gun is like our heavy duty riveter, Big Blue, but without the steroids. Big Blue Junior has the power of the large “heavy duty” riveters in the body of a small one. This tool simply has more pulling force than other tools in its weight class. This is our “full range riveter”. This pop rivets gun tool sets 3/32, 1/8, 5/32 and 3/16 rivets in all materials. Big blue Jr. is ideal for multi-grip rivets and pulls 3/16 Monobolt/Magna-lok structural rivets. This tool provides an economical light-weight solution to placing a wide range of rivets. Nose pieces and service wrenches are included. Recommended operating air pressure is 85-100 psi.
