WeatherTech 81944IMB Rear Side Window Deflectors Matte Black In-Channel Rain Guards

The WeatherTech 81944IMB are precision-fit rear side window deflectors designed specifically for the 2019+ Chevrolet Blazer. Finished in a matte black tint, these in-channel rain guards deliver a clean, low-profile appearance that complements the vehicle's factory styling without the bulk of tape-on alternatives.

These window deflectors install directly inside the window channel — no exterior tape, no drilling, and no modifications to your vehicle's bodywork or paint. The slim mounting flange seats securely in the seal for a snug, OEM-style fit that stays put in any weather or road conditions.

Key Features:

• Matte black tint finish for a sleek, understated look
• In-channel installation — no exterior tape or adhesive required
• Crafted from aerospace-grade acrylic that resists chipping, shattering, and UV damage
• Low-profile aerodynamic design reduces wind noise at speed
• Allows windows to be cracked open to vent interior heat, even in rain
• Helps keep side glass dry during light rain with windows partially open
• Precision-machined for a custom fit to the 2019+ Chevrolet Blazer
• Protects paint by eliminating the need for exterior mounting tape
• Backed by WeatherTech's Limited Lifetime Warranty

Whether you're venting a hot interior on summer days or catching fresh air on a rainy commute, the WeatherTech 81944IMB rear window deflectors — also known as window visors or rain guards — keep the elements out while letting fresh air in.
