Procurement Notes

Verify enclosure compatibility before purchase, as this accessory is specifically designed for 12.00 x 12.00 inch frames. Confirm that the target application requires Type 1 protection standards. Ensure the installation environment is indoors, as Type 1 ratings do not support outdoor exposure. Check for necessary mounting hardware, although Torx screws are typically included. Validate that the required cutout dimensions align with the specified 10 x 10.14 inch opening.

Select this model when securing electrical controls within indoor NEMA 1 environments. It is appropriate for applications needing visual monitoring of switch positions without compromising security. Consider the black steel finish for aesthetic consistency with standard Hoffman enclosures. Ensure the available space accommodates the 13-inch frame size. This accessory is ideal for retrofitting older pull boxes or specifying new installations where locked access is mandatory.
