The zebra comes with a holding harness to avoid damage. In addition, it comes with a couple of staples to hold it together too. But in order to put it in the calculator, you need to remove both the staples and the holder.
The zebra can be used on the previous support in the calculator, or even without support. In case of damaged hardware, it can be removed (provided that the screw posts remain), and the zebra be put on the screw posts - it will work all the same! The plastic of the PCB circuit is far more resistant than the original, and the connectors can handle much better the current than any elastomeric zebra (included the white ones found in some HP41c).
