No. The whole thing is metal Unfortunately the tool they have for it cannot control the tension so you can overtighten them. Or you can tighten by hand and then cut them with cutters but then you risk leaving a nice sharp edge.
They are good for transmission line but questionable for Cat5. I prefer good tape or the HD nylon ties.
