• 3 XL SUPER-STRONG N52 NEODYMIUM MAGNETS: Our unique 3-point magnetic support system uses three enclosed XL N52 neodymium magnets to provide a secure hold from the back and both sides, helping prevent shifting during use.

• INNOVATIVE 3-PART TELESCOPIC DESIGN (16" MIN - 39" MAX): Adjust from 16" to 39" using Units A (16"), B (12"), and C (12"). Built-in stoppers/ridges keep the sections connected, while included transparent tabs help lock your preferred length. Add another (B+C) section to extend approximately 23" more.

• SUPER-EASY 30-SECOND INSTALLATION (MAGNETIC OR ADHESIVE): Snap Unit A onto magnetic floor vents, then slide Units B and C to the desired length. For non-magnetic vents, use the included premium 3M adhesive tabs.

• 1.4" ULTRA-SLIM DESIGN FOR UNDER-FURNITURE FLOOR VENTS: Fits beneath most furniture while redirecting blocked airflow to improve heating and cooling performance.

• EXTRA-THICK & HEAT-RESISTANT: Made from premium 3mm high-strength plastic - about x2 thicker than typical 1-1.5 mm flimsy extenders. Heat-resistant up to 212°F (100°C) for long-lasting durability.
