APWK175NF

Overview

The APWK175NF is a steel window kit manufactured by Hoffman Enclosures, Inc., designed for creating viewing windows on enclosure doors. It features a heavy-gauge cold-rolled steel frame painted in ANSI 61 gray. The assembly measures 19.50 inches in height, 8.00 inches in width, and 0.31 inches in depth, requiring a rectangular cutout of 18.69 inches by 7.19 inches. This component supports NEMA Type 4, 4X, 12, and 3R environmental ratings, ensuring protection against corrosion, dust, and water ingress for both indoor and outdoor applications.

Feature Summary

• Constructed from heavy-gauge cold-rolled steel with a treated surface for paint endurance and adhesion
• Provides inspection visibility while maintaining NEMA Type 4, 4X, 12, and 3R environmental sealing standards
• Designed for simple installation into standard rectangular enclosure door cutouts

Applications

• Indoor industrial control panels requiring visual monitoring
• Outdoor electrical enclosures exposed to weather conditions
• Hoffman Arc Flash Safety Systems integration
• Enclosures requiring NEMA Type 4 or 12 compliance

Procurement Notes

Verify the specific enclosure model compatibility before purchase, as this kit requires precise cutout dimensions of 18.69 inches by 7.19 inches. Confirm that the target enclosure door thickness and material can support the mounting hardware included with the kit. Ensure the required environmental rating (NEMA 4/4X/12) matches the operational site conditions. Check current availability status as lead times may vary based on manufacturing schedules.

Selection Notes

Select the APWK175NF when a durable, corrosion-resistant viewing solution is needed for steel enclosures. The ANSI 61 gray finish ensures color consistency with standard Hoffman enclosure bodies. Consider this option if NEMA 4X performance is required for washdown environments. Verify that the 19.50-inch height fits within the available door space without obstructing other components or latches.

Part Context

This window kit belongs to the Hoffman A-PWK series of enclosure accessories. These kits are engineered to retrofit existing steel enclosures, allowing operators to monitor internal equipment without opening the door. The series maintains structural integrity and environmental sealing standards consistent with the parent enclosure system, supporting various industrial safety and maintenance requirements.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific dimension and rating combination.
