TheCRL Marson? "Big Daddy" Riveter lets you work in hard-to-get-to areas. Use it to replace automotive window regulator and glass stop rivets, plus door handle rivets. The special nose piece provided with the tool must be used for these applications. 3/16" and 1/4" (4.8 and 6.4 mm) nose pieces for other rivet applications are stored in the body of the tool.
