Mounting hole distance on a custom distribution box can look like a small number on a drawing. On site, a few millimeters may decide whether the box fits or fails. If the wall cannot be drilled again, or the box replaces old equipment, that small difference can delay the whole installation.
Hole distance should not be confirmed by casual memory. The customer should provide measurement method, photos with a ruler when possible, and the reference point used. The supplier should check whether the numbers make sense before treating them as final.
Penghan PHLTD can discuss custom distribution boxes and equipment-matching boxes through this measurement discipline. The content should separate mounting hole distance from general outer size because the two are not the same problem.
The installer’s pressure is real. They are the person standing in front of a wall with a box that almost fits. “Almost” does not help them if the holes do not line up.
A good article should teach buyers to respect small dimensions. Confirm early, photograph clearly, and let both sides agree on the measurement before production turns numbers into metal or plastic.
