Thanks. From the picture it looks like a plastic back to me.

It took me a few tries to get the size right on the first zebra strips I had made. Getting the height just right, to get the right amount of compression, is a bit of an educated guess. I'm guessing since you say 'golden zebra' it is of the type shown here: https://www.fujipoly.com/usa/products/ze...ctors.html. These seem to take less pressure to make a good contact than the silicone rubber type. I'm not sure the silicone type, which is easier to get made in small quantities, will work.
