Corner four-way duct connector MAGNAPLAST Ultra UdBED 110/110 146920

The MAGNAPLAST Ultra UdBED corner four-way duct connector is designed for ventilation and air-distribution systems where a compact, angled branch connection is required. This connector accepts 110 mm round ducts on all ports and enables splitting or redirecting airflow in confined corners or compact installation spaces. It is intended for use in residential and light-commercial HVAC installations that need reliable, space-efficient duct branching with consistent inner profiles to maintain airflow.

Advantages

The connector offers a uniform 110 mm diameter across all four ports, enabling straightforward connection to standard round ductwork. Its compact corner-oriented shape reduces the need for multiple fittings and minimizes space consumption at junctions. The internal geometry is designed to provide a smooth flow path to limit turbulence and pressure loss compared with ad-hoc joints. Being part of the MAGNAPLAST Ultra range, it is produced to consistent dimensional tolerances for repeatable fitment and alignment in duct networks.

Suitable for

• Splitting airflow from a main run into two perpendicular branches in corner installations
• Redirecting ventilation ducts in tight or compact spaces
• Residential HVAC systems and light commercial ventilation where 110 mm round ducts are used

Key specifications

• Port diameter: 110 mm (all four ports)
• Configuration: corner four-way connector for perpendicular branching
• Material: durable ventilation-grade plastic (model from MAGNAPLAST Ultra line)
• Compatibility: designed for standard 110 mm round ventilation ducts
• Application: indoor mechanical ventilation and air-distribution systems

How to use

Prepare the duct ends by ensuring they are clean, free of burrs and correctly cut to fit. Align each 110 mm duct end with the corresponding port and push until the connection is fully seated; use appropriate clips, clamps or sealing tape where required by the installation practice to secure joints and ensure airtightness. Position the connector to achieve the desired branch directions and check clearances around the corner to avoid strain on connected ducts. Follow local ventilation codes and manufacturer guidance for supports and spacing.

Usage recommendations

For optimal performance, combine the connector with rigid or semi-rigid 110 mm ducts of matching profile and use mechanical fastening plus sealing to minimize leakage. Inspect the assembly after installation and during routine maintenance to confirm connections remain secure and unobstructed.
