Horix/Hader Bar Instructions
The left side of this picture shows the tunnel created using the processing spacer. The flange of the clip has room to flex out over the height of contour and engage the Hader Bar.
The right side of this picture shows the problems that may be encountered when not using the processing spacer–the clip is locked in acrylic; the flanges of the clip are pressed inward making clip wear very possible, and insertion very difficult or even impossible without breakage. This clip can not expand, or flex outward while going over the height of contour of the bar.
