My guess is no where. It doesn't look factory to me (for a Stern Spider-Man).

My guess is someone added it to block a ball trap, but I have never had a ball trap in my Spider-Man since I had my Sandman "legs" reshaped.

The screw doesn't look right.

The clear plastic and bracket, I wonder if it broke off the clear webbing or the clear plastic by the shooter lane ?

LTG : )

Agree. If it was bigger, has/had an allen head and a lock washer, I'd say coil stop screw. Flat washer on a thumb screw? No idea. Fell off test equipment at the factory maybe?

My guess on the plastic and bracket is it's from one of the side supports on the arch (webslinger assembly) that comes out of the Doc Ock VUK. Specifically, from the part right near where the arch starts. The other (right) side curves at the end. Good pic linked below.

Plastic looks like its from the plastic rail on the VUK behind Sandman.

As for the screw, I found one in my AC/DC Premium and have no idea where it goes. I think it's from the assembly process.

Look at the bottom of the plastic guides for both Sandman and Doc Ock overhead loops it looks like it may be a piece broken off the bottom.
Screw doesn't look like a pinball screw.

Table?

Sorry had to I do not own the game.
It does look like an added plastic to stop ball hang ups somewhere.

Sorry to resurrect an old thread but the same thing has happened to my SM, although my screw looks different. In my case this is from the beginning of the Sandman VUK webslinger clear plastic guide.

I'm just curious if skov refitted it and it it has broken again or not. I'm just trying to figure out if a bit of superglue to rejoin the broken plastic and fixing the screw back in with a bit of thread-lock will do the trick or will it end up being a short term fix?
