More time for miles of smiles, rather than expletives on the side of the road or trail. Yea, we have all been there. The TCS Tyre Plug Kit uses durable "Rocket" anchors (because they look like tiny rockets) that stay in your tire and hold the plug in place. You will not lose a plug. The anchor will hold it in place like a ship at dock.But wait... there's more... You can reuse the anchors when you're all done. It's like a treasure chest when you need to swap-out your tyres. The Rocket Plug Kit also features an 'Extra Hand' tool under the smaller cap. If you haven't pre-loaded the Rocket, the Extra Hand will temporarily plug the hole and take the pressure off while you prepare your Rockets and plugs.
