Dolfamex LISTWA XLCFN 3203M31-FX duct/trim profile

LISTWA XLCFN 3203M31-FX duct/trim profile by Dolfamex is a factory-specified component designed for use in building, ventilation and HVAC installations. The profile functions as a structural or finishing element for ducts, trim runs and assemblies where a matched OEM profile is required for replacement or new construction. Its design supports integration with standard ductwork and architectural trim systems, providing alignment and a consistent finish in mechanical and building envelope applications.

Advantages

The Dolfamex LISTWA XLCFN 3203M31-FX profile offers consistent dimensional accuracy and compatibility with common duct and trim fittings. Its factory specification ensures interchangeability with original equipment profiles, reducing the need for on-site modification. The profile is suitable for finishing applications where a uniform appearance and reliable fit are important, and it supports straightforward installation workflows in HVAC and building projects.

Suitable for

• Replacement of OEM duct or trim profiles in ventilation systems
• New ducting and trim installations in commercial or residential buildings
• Architectural finishing where a matched profile is required
• Mechanical rooms and HVAC distribution channels

Key specifications

• Type: factory-specified duct/trim profile suitable for HVAC and building applications
• Function: structural and finishing element for ductwork and trim
• Compatibility: intended for use where OEM-matched profiles are required
• Application areas: ventilation systems, duct assemblies, architectural trim

How to use

Measure the existing installation to confirm the profile dimensions and verify fit against the mounting surface and adjacent components. Trim or cut the profile to the required length using appropriate metalworking or cutting tools, and prepare mating surfaces to ensure a flush fit. Install the profile according to the duct or trim system requirements, using recommended fasteners, seals or adhesive where necessary to achieve mechanical stability and airtightness in ventilation applications. Follow applicable local codes and manufacturer guidelines for secure attachment and sealing.

Usage recommendations

Store the profile flat in a dry environment prior to installation to prevent deformation. Verify compatibility with existing system components before installation and use corrosion-resistant fasteners and appropriate sealing materials in HVAC applications to maintain long-term performance.
