Shower Door System Anti-Torque Back Plate Device Roller and Roller Stops

An anti-torque and anti-lift device for a roller that rides on a fixed rail comprising:

• a roller with an outer diameter and inner diameter wherein a bearing is fixed into the inner diameter of the roller and said bearing having a front face, rear face and inner diameter;
• a threaded shaft inserted into and through the inner diameter of the bearing with a cap nut torqued up against the rear face of the bearing on one end of the threaded shaft and an inner shaft face of a castellated nut and shaft component torqued up against the front face of the bearing on the other end of the threaded shaft;
• the castellated nut and shall component having an inner diameter tapped through hole, an inner shaft face and an outer castellated nut face, the outer castellated nut face having keyway slots;
• a circular face plate having a front face, a rear face, an inner diameter through hole, protruding keys located on the rear face and an anti-lift hook standing off of the circumference of the circular face plate projecting out past the rear face perpendicular to a plane located on the rear face of the circular face plate;
• the rear face of the circular face plate secured up against the castellated nut face of the castellated nut and shaft component by a screw inserted through the inner diameter through hole of the circular face plate and into the threaded internal diameter of the castellated nut and shaft component such that the keys on the rear face of the circular face plate interface with the keyways in the outer castellated nut face prohibiting the circular face plate from rotating relative to the roller as the outer diameter of the roller moves along the fixed rail and the anti-lift hook of the circular face plate projects down and into a channel below the fixed rail on which the outer diameter of the roller rides prohibiting the roller from lifting up and off of the fixed rail.
