This is for the Gen 3 Starlink system that uses an ethernet cable to connect the dish to the router. The grommets fit an ~11/16" (17.5mm) hole drilled into the side of the house, and the diameter for the cable is ~1\4" (6.4mm). The hole size of the clips is ~0.2" (5mm). Starlink sells their routing kit for $32, although it comes with drill bits and other things. I just needed the grommets and clips.
