Englisch > Deutsch Technik E-Technik/Elektronik Wafer carrier

This is from a catalogue with all kind of different products.

I know that the "H" bar is the end of the wafer carrier that has only one crossbar, but I don't know ther German term for this.

The above term shows up in a table with the following entries:

Part Number: ABC123
End Wall Configuration: Flanges
***"H" Bar End Flanges***: Yes
Compatible Boxes: A1, B2, C3
Material: XYZ


Other context is a list of bullets, where "H" bar shows up as well:

- Open sidewall style with wraparound wash slots
- "H" bar equipment interface
- Protective side wall design guards against damage from operator contact


Any help from people specializing in this field is greatly appreciated.
Thanks
