Strongbox

Since 1980 StrongBox? is the Heavy-Duty Rack-Mount Chassis Most Trusted by Engineers.

The most obvious difference between STRONGBOX? Heavy–Duty Rack–Mount Chassis and “regular–duty” versions offered by other manufacturers is the thickness of the aluminum from which they are made. The main structural members of their chassis are 0.090″–thick. Similar parts of other units are only 0.040″ to 0.063″. Their heavy–duty chassis provide more than twice the intrinsic strength without using hard–to–machine steel or added internal framework sub–assemblies. Specify STRONGBOX? to keep your project hassle–free.

Their Heavy–Duty Rack–Mount Chassis assemble with stainless steel machine screws, lock washers, and captive PEM nuts which do not react galvanically with aluminum. Many other chassis use thinly plated, carbon steel, sheet metal screws or loose bolts and nuts. Captive machine hardware goes together precisely, solidly, and permanently. Sheet metal screws have been know to vibrate loose, or spontaneously disassemble when worn plating permits an electrolytic reaction with chassis metal. Besides the materials used in manufacture and the hardware used for assembly, STRONGBOX? chassis configurations are engineered to support greater static and dynamic loads. Main load–bearing panels are stiffened and supported by wide flanges and from six to ten sets of hardware, and are anchored to who support panels of equal or superior strength. The resulting chassis are rigid, solid, cohesive unit–structures which support and protect their contents under extremely stressful conditions. Protect your electronics inside a chassis built like a bank vault, but don?t spend a fortune to do it.
