Right Angle SeamBuster has greater reach Steck Manufacturing Co. introduces the Right Angle SeamBuster, No. P/N 20016. Adding a 90° angle along with a third sharpened edge to Steck's SeamBuster allows techs to gain easy access to hard-to-reach pinchwelds. A 90° angle is designed to allow bi-directional hammer use on quarter panels, rockers and any other pinchweld. The sharp end allows for penetration between the panels, and two lower edges allow for side impact to drive the panels apart. SeamBuster is made from alloy steel and has a cushioned handle that absorbs shock.
