With the introduction of the Summit Bar, ARB’s engineers required a new clamping system to attach the front rail section to the 60.3mm outer frame of the bar. Rather than simply introducing a larger side rail clamp to suit the larger tube size, ARB Engineers have developed a neat and practical solution. The design registered clamp provides a number of advantages over a standard side rail clamp. Two Spacers are included to allow for different tube lengths due to variances in bar to chassis tolerances. The ARB branded cover also allows for adjustment in the side rail to upright positioning. The step section is an anodised silver extrusion featuring front to rear ridges for grip. Please note that the extrusion is supplied with the front section (either rail or return) selected.
