The Hoffman Enclosures F66LA is an adjustable steel telescopic fitting designed for use with NEMA 3R lay-in wireway systems. It features a gray finish and is constructed from steel material. The component has a width of 6 inches and a height of 6 inches, with an overall length of 10-1/4 inches. It provides quick length compensation without the need for cutting or welding.
Verify that the selected component matches the specific dimensional requirements of the wireway system. Confirm compatibility with NEMA 3R standards before procurement. Ensure the steel construction and gray finish meet project specifications. Check official documentation for any specific installation constraints related to the telescopic mechanism.
Select this fitting when working with NEMA 3R lay-in wireways requiring adjustable length connections. The 6-inch width and height must align with existing wireway dimensions. Consider the 10-1/4 inch length range for adequate adjustment capability. Steel construction ensures durability in industrial environments.
This component belongs to the Hoffman Enclosures line of wireway accessories. It is specifically engineered for integration into larger electrical distribution infrastructure. The product supports standardized wireway assembly processes by eliminating manual modification needs.
No public confirmed substitute part numbers are available.
