The diameter of rod holes must be _________________ than that of the rods.

• A. the same
• B. 1/8 in. larger
• C. 1/16 in. larger
• D. 1/4 in. larger

Answer: (C)

The correct completion of the statement regarding the diameter of rod holes is that it must be 1/16 inch larger than that of the rods. This requirement ensures that there is sufficient clearance for the rods to be installed without binding or excessive friction, which could affect their performance. The added space allows for potential variations in rod dimensions and ensures proper alignment when the rods are placed into the holes. This specific measurement not only facilitates ease of installation but also contributes to the overall integrity and functionality of the private fire service mains system as specified by NFPA 24. Such details are critical in maintaining effective fire protection infrastructure, as they relate to ensuring that systems operate as intended without interference from improperly fitted components.
