Two alternative mounting methods and devices for mounting rails achieve new points of mounting (8) by adding new pitch-holes to mounting rails (2) and using either adjustable cage-nuts or cage-nuts containing two nuts in their respective pitch-holes. The shape of the new pitch-holes preserves the structural integrity of mounting rails (2). The number of mounting points and possibilities can be dramatically increased, thereby satisfying various ventilation and pass-through requirements between devices (5). |
