Spreader tips not captive?

[Beezer]

Hi there thanks for the reply. The spreader tip does indeed allow fore and aft movement as well as vertical movement. The shroud is only captive within the tip. I may be overestimating the size of the opening it sits in. Might be more like an inch and a half wide. There is no obvious place to sieze the spreader tip in place and almost as importantly there is absolutely no notch to seat the wire in if it was wired in place, which led me to believe the shroud was supposed to be unconstrained. But really I don't like the situation and feel like it should be more secure. I can only find photos of "twist lock" spreader tips on rigrite but these while functionally similar are not at all the same and appear to allow more play. Are these really oddball then? I was hoping someone had seen something similar. I don't have a photo unfortunately. Thanks very much!
