These are by far the best wire clips I can find. I used a construction stapler, it wasn't strong enough. I've used regular metal clips but they are difficult to work with while also holding the wire in place. This is great because you can push the plastic piece into place, effectively holding the wire in place, and then drive in each nail individually or all at once. Hands don't bother, glasses enter easily. No more bending clamps. Those are the only ones I would buy.
