Thanks for reaching out to find an answer, I have linked some information below.

**Vent Cover for Ventline Old-Style Rounded Dome Trailer Roof Vents - Smoke # BV0554-03.
**Replacement Dome for Fan-Tastic Vent RV Roof Vents - Tinted # FVK1020-19.

Vent domes and the replacements for them all have a universal size. However, you do need to make sure you get the right brand because they have different methods of connecting to the vent and the lift arms will be in different locations. I linked two different examples above.

If you look at the bottom of you vent dome look where the lift arm connects. It will be either side, in the middle or both sides. You can reply back with the make and model of your vents and we can get you the proper replacements.
