Ventilation flat duct end cap AWENTA KP55-30BR for 55×110 mm rectangular duct, brown

The AWENTA KP55-30BR end cap is designed to close the open end of a flat rectangular ventilation duct with internal dimensions of 55 × 110 mm. Made for use with flat-profile HVAC channels, this brown end cap provides a sealed termination that prevents air leakage and stops dust, insects and debris from entering the ductwork. The component is compatible with typical residential and light commercial ventilation systems that use 55×110 mm rectangular ducts and is intended to simplify finishing of duct runs and branch terminations.

Advantages

The end cap offers a simple, secure closure that reduces unwanted airflow and helps maintain designed ventilation performance. Its shape matches flat duct profiles to ensure a snug fit and minimal gaps. The brown color enables a discreet installation in visible areas or behind trim. The cap is lightweight, easy to handle and requires no special tools for fitting, which speeds up installation and maintenance tasks.

Suitable for

• Sealing the open end of 55 × 110 mm rectangular ventilation ducts
• Terminating flat duct runs in residential HVAC systems
• Closing unused branch outlets in light commercial ventilation installations
• Preventing debris and pests from entering ductwork during construction or storage

Key specifications

• Compatible duct internal size: 55 × 110 mm (rectangular / flat profile)
• Color: brown
• Function: end cap / closure for rectangular ventilation ducts
• Application: ventilation systems for residential and light commercial use
• Material characteristics: lightweight, suitable for standard HVAC installation

How to use

Ensure the duct end is clean and free of loose material. Align the end cap with the rectangular profile of the duct and press it into place until it seats evenly along the edges. If required, secure the cap with appropriate HVAC tape or mechanical fasteners compatible with the duct material to create a more permanent seal. For temporary closures during construction, a simple push-fit will normally suffice.

Usage recommendations

Check compatibility with the specific 55 × 110 mm duct profile before installation. For permanent installations, inspect the fitted cap periodically and re-seal or replace if signs of wear, cracking or loose fit occur. Avoid exposing the cap to direct heat sources or corrosive chemicals that could degrade the material.
