Driving fasteners in the recesses is a simple operation, and the StepMaster® can drive 1 to 6 fasteners per corner – stacking in either position as required! With the Multi-Shooter option, fasteners can be driven in up to 4 positions. Micro-Corrugated or “V” fasteners used with the StepMaster® produce Strong Tight Corners of matchless strength!

MitreNailer fasteners used with the StepMaster® means secondary finishing operations are unneccesary.  One-step assembly eliminates kerfing, slotting and putty, and results in high production rates exceeding 1000 frames per shift. Computer controlled: The StepMaster® control panel combines easy access for the operator and simplicity of use.
