BESWEL Sideways Air Vent Extender for 3"-6" Vents | Heat-Resistant up to 230°F

Enhance Airflow Exactly Where You Need It

The BESWEL Sideways Air Vent Extender helps you guide conditioned air exactly where it matters. Built from food-grade polypropylene, it holds up to routine HVAC heat while staying slim and unobtrusive beneath furniture or along floor registers.

Premium materials and practical design

Designed to endure warmth up to 230°F, the extender uses a robust 1.5mm thickness for everyday durability. This combination supports steady performance through seasonal changes and busy households.

Easily attach and adapt to your vents

Two strong neodymium magnets snap onto metal registers for fast, tool-free setup. For non-metal vents, a high-viscosity adhesive tape is included as an alternative mounting option.

Versatile reach and flexible routing

The extender fits vents 3-to-6 inches wide and can be deployed to extend from 12 to 22.3 inches in length, letting you direct air toward seating areas, workspaces, or perimeters where it matters most.
