The F66LX is a non-lay-in hinged cover cutoff fitting manufactured by nVent HOFFMAN. Constructed from mild steel with a galvanized gray finish, this component belongs to the Hoffman Concept Type 4 and 12 Series. It features a flush quarter-turn latching mechanism and is designed for indoor use. The fitting allows for custom length adjustments up to 12.00 inches (305 mm) by shortening both the body and cover sections.
Verify that the specific application requires a non-lay-in configuration, as lay-in alternatives exist within the F66 series. Confirm the required cut-off length does not exceed the 12-inch maximum limit. Ensure compatibility with existing galvanized steel wireway components to maintain consistent corrosion resistance and structural integrity in the installation environment.
Select the F66LX when a hinged, non-lay-in solution is necessary for wireway ends or transitions. This model is suitable for environments requiring Type 4 and 12 protection ratings. Consider the adjustable nature of the fitting, which allows field modification to fit specific spatial constraints up to the specified maximum length.
This part is part of the Hoffman Concept family, which includes various enclosures and accessories. The F66LX specifically addresses the need for customizable wireway endings in industrial settings where standard fixed lengths are insufficient. It complements other F66 series components like straight runs and elbows.
No direct public substitute part numbers are confirmed for this specific non-lay-in cutoff fitting. Alternative solutions may involve using standard wireway sections and modifying them on-site, though this may affect the aesthetic and functional consistency of the quarter-turn latch system.
