Springs, eh? That's interesting.

Yep. I like the clamps. They look the same as the ones that were used in Westinghouse cobraheads. The nuts are pretty interesting too. They are those ones that have like that plastic coating in the threads.

They're lock-nuts, probably so the force of the springs doesn't loosen the nuts over time.

That is the classic Westinghouse slipfitter design (sans springs and locknuts) carried over into the 4th generation silverliners.

@Mike, the springs are actually very weak if I remember right. There is just enough pressure to keep the clamps in the open position.

@NiMo, yeah I love these Westinghouse style slipfitters.

Cooper Lighting OVW

Here is a closeup of the slipfitter clamps and bolts inside the OVW. Notice how the clamps are sitting on springs.
