HVAC Louver Flange Kit

The Dayton 45C677 flange kit is built for 60x60 inch aluminum combination louver dampers and drainable fixed louvers. It provides the structural frame needed to mount those units securely in commercial or industrial ventilation systems. The kit includes all necessary mounting hardware for a complete installation.

Extruded Aluminum Construction

Made from extruded aluminum, the flange resists corrosion and handles airflow stress without warping. The rigid material keeps the louver assembly stable during normal system operation. No moving parts or powered components are present, so the kit adds no noise or power draw to the installation.

Replaces Damaged or Missing Frames

This kit replaces a bent, corroded or lost flange on existing 60x60 inch louver dampers. The upgrade is worth it when the original frame no longer seals properly or cannot support the louver weight. It is not suited for smaller louver sizes or for dampers that use a different mounting pattern.

Questions about this item

How is the 62-1/2 inch flange kit installed on a 60x60 louver, and what step is often missed?

The kit fits around the 60x60 opening with included hardware; the step often missed is verifying the flange sits flush before tightening all screws.

What maintenance or replacement will the extruded aluminum flange need over time?

The aluminum resists corrosion; periodic inspection of fasteners and cleaning of debris is the only upkeep required.

What limit appears first when the flange is under sustained thermal cycling?

Repeated expansion and contraction can loosen mounting hardware, so re-torquing bolts is the first maintenance limit.
