Procurement Notes

Verify that the specific order matches the screw-cover variant and confirms the absence of knockouts. Ensure the required NEMA Type 3R rating aligns with environmental exposure needs. Confirm UL 50/50E and CUL listing requirements are met for the intended installation jurisdiction. Check dimensional constraints against the 18x12x8 inch specifications before procurement.

Selection Notes

Select this model when outdoor rain protection is necessary but submersion resistance is not required. The lack of knockouts requires field drilling or alternative entry methods. Verify that the 18-inch height and 12-inch width accommodate internal components. Consider the screw-cover operation for frequent access needs versus quick-release alternatives.
