EMS Flightcases & Bags
You can place these small PVC rings between the nut and your 19 inch device. In this way, the rack ears of your device do not get damaged.
This 19 inch rack panel comes in handy when you have a little space left in your flight case that is too small for a 1U panel. Because it is only 0.5U high, this blind plate can be mounted in small spaces that would otherwise remain open.
This EMS rack-ware installation kit is specifically suited for EMS flight cases. If there is very little or no rack-ware at all included with your flight case, this kit can help you out.
