Vent Cover Measurement Guide
1. Remove current vent covers |
2. Measure the existing hole |
 |
 |
| Note: Do NOT measure the existing air vent cover. Every vent cover has its own unique size of frame so we cannot use the old vent cover as an accurate measurement guide. | Note: For custom size vent covers please send the exact dimension of the existing hole. This helps determine a more accurate measurement and what size would fit best. |
3. Determining a kul grille size:
