Sorry to hear that, could have been worse.
Live and learn.

What pin are we talking about?

Here is a the replacement shell for the topper:

I'd make sure no connections jarred loose but it sounds like you've got away with it. Check J120 is good and tight because FT burns the GI connector more than I burn toast.

And that's a lot.

I think we all have live and learn stories about our pinball machines that we could share such as yours.

Sorry to hear, but the main thing is it sounds like no big damage and the plastic dome can be easily replaced. If your plastic dome was anything like mine that can on my FT, it probably needed replacing anyway.

Marco has them for $68. Easy Fix!

How is this possible other than wrong/not enough shrink wrap? Did it somehow catch/rip apart on something?

I will use shrinkwrap before straps anytime I can....

When I first saw that pic, I didn't realize it was rotated.. I thought it had fallen over on it's side

Twice I've cut the shrink wrap without holding onto the backbox and let it slam to the ground (last time it hit my toe). As smart as some of us are, we can be really dumb (gee, what happens if I cut the one thing supporting this backbox?)

I am not a big fan of shrink wrap. Too many people are thrifty with it and don't put on enough passes, but that is hard to tell until it gives way. Also if you are shoving the pin in and out a of a car/truck it is very easy for the bottom (hidden) side of the wrap to get torn up and you won't know it until it gives way.

You can get cheap ratchet straps for $3 each at Lowes in a four pack. Rated for 600 lbs. They are nice for $3 each.

Every fold down head pin I sell/trade comes with a "free" ratchet strap. Just put some newspaper or other padding at all of the areas where the strap will rub on the cabinet.

What I like the wrap for is when I am transporting a pin in an open bed truck and I want to keep it nice and clean. Plastic wrap is excellent for that job.
