Frequently Asked Questions
Q: How do I know if I need to replace my AC mounting bolts?
A: Replace bolts if you notice your rooftop AC unit is loose or rattling while driving, if bolts are visibly corroded or stripped, or if you're performing routine AC maintenance. Loose bolts can lead to roof leaks and AC failure.
Q: Will this bolt fit my Dometic AC unit?
A: This is a genuine Dometic OEM part designed for standard rooftop AC mounting applications. Verify your AC model number and consult your owner's manual or contact our support team to confirm compatibility with your specific unit.
Q: How many bolts do I need to replace my rooftop AC?
A: Most Dometic rooftop AC units use four mounting bolts. We recommend replacing all four at the same time to ensure even pressure distribution and prevent future leaks or movement.
