The Big Daddy is Marson's most versatile and powerful hand riveter, taking the hard work out of setting large diameter blind rivets. Its extra-long handles provide excellent leverage and permit working a foot beyond natural reach. Other features include a patented bearing design, self-adjusting two-piece jaws and single-unit body construction with a steel insert to provide stronger threads for the nosepieces included. In addition, the Big Daddy features a double-gear reduction system which easily sets from 1/8in. to 1/4in. diameter Klik-Fast rivets in all alloys, including 1/4in. Klik-Split® and 3/16in. and 1/4in. Klik-Lock™ rivets. And a one-piece collet case eliminates the need to adjust the tool when changing rivet diameters. The Big Daddy comes with 5/32in., 3/16in. and 1/4in. nosepieces which are stored in the body. It comes with 39009 attached, extending the tool's reach by an additional 2 1/2in.
