The CT6646RSS is a reducer fitting within the Hoffman Clean Tray series, designed for indoor cable management applications. Constructed from Type 304 stainless steel with a brushed #3 finish, it transitions cable tray dimensions from 6 inches by 6 inches to 4 inches by 6 inches. The component features an 18-gauge thickness and holds a NEMA Type 1 rating, ensuring basic protection against falling objects and limited ingress of solid foreign bodies in controlled indoor environments.
Verify that the specific application environment remains indoors, as the NEMA Type 1 rating does not support outdoor or wet locations. Confirm compatibility with existing 6x6 inch tray sections to ensure proper fitment during installation. Ensure the required transition size matches the 4x6 inch specification to avoid structural misalignment.
Select this component when a reduction from 6-inch width to 4-inch width is required within a stainless steel cable tray system. The Type 304 material offers standard corrosion resistance suitable for most indoor industrial settings. Consider the 18-gauge construction for adequate mechanical strength relative to the supported cable load.
This reducer belongs to the Hoffman Clean Tray series, which focuses on organized cable routing solutions. It serves as a transitional accessory rather than a primary enclosure, allowing for flexible layout adjustments in complex wiring scenarios where varying tray widths are necessary.
No direct substitute part numbers are publicly confirmed for this specific reducer configuration.
