JIANBENKJ Wall Vent Cap for Microwave Exhaust | Stainless Steel

Overview

The JIANBENKJ wall vent cap is a sturdy, exterior termination designed for outdoor air exhaust from kitchen and bath fans. Crafted in rust-resistant stainless steel, it provides a clean, durable finish for 3-1/4 inch by 10 inch rectangular ducts, connecting to microwave vents, range hoods, and other exhaust applications. The design blends practical functionality with a streamlined look that suits modern homes and outdoor installations.

Key benefits at a glance

• Spring-loaded damper with a silicone cushion creates a tight seal when not in use, helping reduce drafts and noise.
• Bird-proof screen opens for easy cleaning, so debris and leaves can be cleared without removing the whole cap.
• Durable stainless steel construction resists rust and corrosion, supporting long-term outdoor use.
• Pre-drilled holes and foil tape-enabled sealing simplify installation and provide a reliable exterior vent connection.

In everyday use, this vent cap offers a quiet, low-maintenance solution for terminating outdoor exhaust. The damper and gasket work together to minimize vibration, while the screen keeps small pests from entering the ductwork. The result is a practical upgrade that helps, over time, maintain efficient ventilation for your kitchen or bathroom exhaust needs.

Fitment and technical details

The overall size is 10-1/4 inches wide by 3-2/5 inches high, designed for 3-1/4 x 10 inch rectangular ducts. The duct fitting extends 4-7/8 inches from the cap to allow a secure connection to rectangular ducting. Note that this cap is not intended for dryer vent use, and it is optimized for kitchen range hoods, microwaves, and bathroom exhaust fans that vent outdoors.

Installation highlights

• Easy, tool-free setup with pre-drilled holes and foil tape for a tight seal.
• The bird screen opens with a screwdriver for quick cleaning of accumulated leaves or debris.
• Rugged stainless steel stands up to outdoor conditions, reducing the need for frequent replacements.

Usage scenarios

Ideal for microwave vents, range hood vents, kitchen wall vents, external extractor walls, bathroom exhausts, and other outdoor venting needs. The combination of a protective damper, gasket, and cleanable screen makes it a versatile choice for exterior vent terminations that face weather and seasonal dust.

Care and maintenance

Wipe down the exterior periodically to remove dirt and rinse away residue. Use the screwdriver to open the screen for routine cleaning. Regular inspection helps ensure the damper and seal continue to function smoothly over time.

Warm ordering tips

Please measure your duct diameter before ordering to ensure a proper fit. The cap is designed for 3-1/4 x 10 inch rectangular ducts and should be paired with appropriate ductwork and sealing practices for a durable exterior finish.
