The A12124SUG is a Type 1 screw-cover pull box extender manufactured by Hoffman Enclosures, Inc. Designed to fit 12.00x12.00 inch enclosures, this component is constructed from galvanized steel to provide corrosion resistance in indoor environments. It serves as an extension for existing pull boxes, eliminating the need for custom-sized units in commercial and general industrial applications.
Verify that the base enclosure matches the required 12.00x12.00 inch dimensions before procurement. Confirm that the application environment is suitable for Type 1 ratings, which are intended for indoor use only. Ensure compatibility with existing screw-cover accessories if integration with other components is planned. Check for included mounting hardware availability in the specific order configuration.
Select this model when an existing 12x12 inch pull box requires vertical or horizontal extension without replacing the entire unit. The galvanized finish is appropriate for standard indoor conditions where high humidity or outdoor exposure is not present. Consider the Type 1 rating to ensure it meets local code requirements for dust-tight and light-tight protection in controlled environments.
This extender belongs to the Hoffman screw-cover pull box series, designed to integrate seamlessly with standard NEMA Type 1 enclosures. It allows for modular expansion of electrical distribution points. The product line focuses on providing standardized solutions for common wiring needs, reducing lead times associated with custom fabrication while maintaining structural integrity.
No public confirmed substitute part numbers are available.
