The Dometic 90-Degree End Ducted Air Distribution Box (Part# 9108849719) is a critical component for RV air conditioning systems that require directional airflow at the end of a duct run.

Frequently Asked Questions

What's the difference between this and a straight end box?

This 90-degree end box redirects airflow at a right angle, making it ideal for corner installations or when you need air directed perpendicular to the duct run. A straight end box directs air in line with the duct. Choose based on your specific installation requirements and space constraints.

Can I use this in the middle of a duct run?

No, this is specifically designed as an end-of-run distribution box. It's a terminal point in your ducted system. For mid-run applications, you would need a different type of duct fitting or distribution box designed for through-flow.

Will this fit my existing ductwork?

This end box is designed to fit standard Dometic ducted air distribution systems. Check your existing end box and duct diameter to confirm compatibility. If you're replacing an existing Dometic 90-degree end box, this should be a direct replacement.

How do I know if my end box needs replacement?

Common signs include cracked or broken housing, poor airflow from the vent, rattling noises during operation, or visible damage from UV exposure or impact. If air is escaping around the box rather than flowing through it properly, replacement is recommended.
