BTB™ Depth Control Arm

This depth control arm is made with a large plastic wheel and intended for use under blades WK5 & WK5S when removing backfill from the glass edge (buses & trains). In this application, the wheel rolls along the glass. It is also used over other flat blades such as WK2S to control cutting depth for longer reach cutting applications. When used in this application the wheel rolls along the window glass or vehicle body trim.
