Great for back up or replacement
The Mother board comes with its own endcaps these are more for the extra attachment is you do not want to attach them to the mother board and would want to use them separately. Also good to have around incase some of the ones you have break, it is a a very durable plastic but there are always accidents.
Endcaps for any part of the OCB MOBO tray motherboard system!
