FE-3X™扩展架可扩展范围并提供深入的机架服务器支持。设计用于 SL-500FX™前装式升降机 和 SL-500FXL™ Extended Height Lift，此组合为任何机架内的服务器提供了严格的支持。非常适合制造商和系统集成商。

The FE-3X plate is a “dual-purpose plate.” It can be used to get deeper into a rack (providing an additional 9″ into the rack), and it can also be used like the LE-500X to provide assistance for unboxing servers and other IT equipment. It comes with hooks and straps just like the LE-500X.
