Notched RV Roof Vent Prop Stay
A replacement prop arm for manual caravan/RV roof vents and hatch lids. It's a 168 mm long, 18 mm wide, 7 mm thick bar with a bossed 5.5 mm M5 pivot hole at one end. At the other end is a 90 mm slot with six notches 16 mm apart, so the stud on the lid can rest at six different opening heights. The slot lets it fit lids whose stud sits anywhere along that range, so you don't need the discontinued dealer part.
