The little clippy widgets (looks kind of like @) on some oldschool racks, that hold the nut in place for the hex-head bolt. Why these were considered desirable is beyond me.
We've got a bunch of racks like that (and my PDP8 rack at home has them as well). The nice thing about them is if you get a screw cross threaded and chew up the threads, you can pop the clip off and put a new one on. With rack rails that are pre-threaded, you've just lost the use of a hole (or you can try to re-tap the hole, maybe ending up having to use a non-standard screw for just that hole). -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
