The nVent Hoffman F44G33R is a Type 1 wireway reducer designed for the Lay-In series. Constructed from mild steel with a gray powder-coated finish, it transitions from a 4-inch by 4-inch opening to a 3-inch by 3-inch opening. The component measures 4 inches in height and 2-1/2 inches in depth, manufactured from 16-gauge material. It functions as a fitting to combine trunking sections of different sizes within electrical enclosures.
Verify that the specified application requires a Type 1 rated component suitable for indoor use only. Confirm compatibility with the specific Lay-In series trunking dimensions before purchase. Ensure the installation environment does not require higher ingress protection ratings than Type 1 provides. Check local codes regarding steel enclosure usage in your specific facility.
Select this reducer when transitioning from a 4x4 inch to a 3x3 inch wireway size within a Lay-In system. Choose this model if a NEMA Type 1 rating is sufficient for the installation environment. Consider the 16-gauge steel construction for standard mechanical durability requirements in indoor electrical panels.
This component belongs to the nVent Hoffman Lay-In series, which offers modular cable management solutions. The series utilizes flat covers for easy access and expansion. Reducers like the F44G33R allow for flexible routing and size changes within the same trunking family without requiring adapters or complex fittings.
