Lighting tracks that are four feet or less in length must be fastened at a minimum of how many places?

• A. 2
• B. 4
• C. 6
• D. 8

Answer: (B)

The main idea here is how lighting track systems are supported to stay rigid and safe. When a track carries fixtures and is attached to the building structure, securing it at multiple points distributes the load and resists movement, sag, or misalignment that can occur as you slide fixtures along or as forces act on the track. For a track length of four feet or less, four fastenings provide enough support to keep the track stable and evenly loaded. This means securing at multiple points along the run—typically at the ends and at additional positions along the length—to prevent bending, misalignment, or looseness that could stress joints or mounting hardware. Fewer than four fasteners could allow movement or sag under load, while more would be more than the specified minimum for this short length. So, the minimum number of fastenings for a four-foot-or-shorter track is four. Longer runs would require fasteners spaced at appropriate intervals to maintain the same level of stability.
