1.20 Material and Finish

The fuse platform chassis and brackets are made of 16 gauge cold rolled steel. The fuse platform and brackets are finished with powder paint that is putty white color.

1.21 Weight

The weight of the fuse platform is approximately 12.5 pounds (5.675 kilograms).

1.22 Cooling

Vent openings are provided in the top and bottom of the fuse platform. The vent openings allow convection cooling of all components without the use of fans or blowers. A minimum of 1.75 inches (4.45 cm) of air space (one rack space) must be provided above and below the fuse platform to allow air to circulate freely.
