How does one seal the small, 3/8th inch knockouts in metal octagonal ceiling fixture boxes (the ones that have the clamps)? I've looked for seals and the smallest is 1/2inch trade size, which is actually close to an inch and is too large for the smaller knockout. Are the internal Romex wire clamps, if tightened without a wire in them, considered adequate to seal the knockout?
