Overview

The Hoffman APWK711NFSS is a stainless steel enclosure window kit designed for industrial applications. It features a 304 stainless steel frame and a single-piece polycarbonate window. The unit measures 9.50 x 13.50 inches with a thickness of 0.31 inches, requiring an 8.69 x 12.69 inch cutout. It provides NEMA 3R, 4, 4X, 12, and 13 protection ratings. The kit includes UL 508A and CSA approvals for indoor and outdoor use.

Feature Summary

• Constructed from 304 stainless steel frame material for durability
• Single-piece polycarbonate window resistant to oils and cutting fluids
• Compatible with standard rectangular enclosure cut-outs
• Suitable for both indoor and outdoor environments

Applications

• NEMA Type 4X enclosures
• NEMA Type 12 and 13 enclosures
• Indoor industrial control panels
• Outdoor equipment housing

Procurement Notes

Verify the specific enclosure model compatibility before purchase. Confirm that the required cutout dimensions match the 8.69 x 12.69 inch specification. Ensure the application environment aligns with the NEMA 3R, 4, 4X, 12, or 13 ratings. Check for any regional certification requirements such as UL 508A or CSA approval.

Selection Notes

Select this model when corrosion resistance is critical due to the 304 stainless steel construction. Choose this option for applications requiring visibility into the enclosure while maintaining environmental sealing. Consider the polycarbonate window material for impact resistance compared to glass alternatives. Verify that the frame finish meets aesthetic or functional requirements for the installation site.

Part Context

This component belongs to the Hoffman APWK series of window kits. These kits are designed to retrofit existing enclosures or be integrated during manufacturing. The series offers various sizes to accommodate different panel dimensions. The APWK711NFSS specifically addresses the need for robust, weather-resistant viewing ports in harsh industrial settings.

Replacement Considerations

Check for direct substitutes within the Hoffman APWK series that match the 9.50 x 13.50 inch footprint. Verify if alternative materials like aluminum frames are acceptable if stainless steel is not strictly required. Ensure any replacement maintains the same NEMA rating and cutout dimensions.
