It's kind of hard for me to tell from just the picture, but my best guess is that it could be some sort of flexible cable/wire with a white outer sheathing on it. After looking up "Siamese Cable" and looking at it again, I think you might be right. Considering its free, and if it's not to far from you, I would jump on it. Considering the TV,
microwave, shelving and other items he/she has. Not to mention if you have a
business card or can let him know you recycle other metals and
e-waste (if applicable).
