Mysterious rubber !

[Just Love Pinball]

Hi all, has anyone got any idea what this is for? I've seen it on a number of my machines - on the playfield support bar, a single rubber band. Should I make sure all of my machines have one installed? What dies it do? Thanks in advance!

It’s to tie it into position when it was shipped originally.

I always wondered why they were there
