Description
The MC-51-903 cuts the center groove in door frame stile and rail stock for the MC-51 series 8-piece double-sided shaper door system at Mini-Pro 3/4″ bore — the groove that receives the door panel tongue (machined by MC-51-500) in the assembled double-sided door. Profile 903 specifies the groove width and depth for a particular panel thickness; six center groover profiles are available (903–908) corresponding to different panel material thicknesses or groove configurations. Verify the required panel thickness and corresponding groove profile before ordering. 3-wing, 3/4″ bore, 2-15/16″ OD, CCW. Bearing AM-90-027. Pro-Line counterpart is FB-DS-PL-903 (1-1/4″ bore, 4″ OD, bearing AP-90-044).
