The TDC (Top Down Centre) Trolley features modifications on the slide bars on each side compared to the original. This ensures a tighter fit onto the chamber to achieve an absolute Top-down-center push of force onto the R-hop patch while preventing any tilting.  The overall contact area has been extended by 0.5mm compared to the original to cover most hop-up windows, ensuring all areas of the ER-hop patch are equally pushed down. In addition, this covers more of the chamber window for an increased air seal.
