I don't quite get what makes this DigiKey part suitable for the role of a fused resistor. I do see that it has specs for 'fusing behavior' but that aside, I don't see that this series is marketed / sold as a "fusible resistor". One reason I question it, is the fact that the fusing ratings are only

A friend mentioned that there was a thread about the card guides in an 8a or 8e chassis but I was unable to locate it so I am posting this as a new thread as it has more relevance than just specifically those card guides. Nylon is hygroscopic. Hygroscopic means it has the ability to absorbs water.
