This affordable gauge cup fits most 52mm gauges. The cup can pivot AND rotate on its base. The base can be bolted down or you can secure it with the included double-sided tape disc for a no-drill install. A hole in the bank of the cup allows for neat routing of wires and tubing -- you even get a length of heat-shrink tubing to keep everything looking extra-neat! Shown above with gauge installed. Gauge not included, of course.
