Ultimate MagnumSpike

There are two types of MagnumSpike! Systems with all the same exceptional features: the original MagnumSpike! and the Ultimate MagnumSpike! Both systems come in convenient deployable lengths (10 ft, 12 ft, 16ft, and 25 ft). in both polymer hard case or ballistic nylon case (wrap & roll). All models have the same patented, non-clogging spikes that penetrate and deflate tires in predictable short distances. The Ultimate MagnumSpike! uses a friction-free spike release system. The spikes are secured and suspended on pins. When the vehicle tires run over the spikes, the spikes are pushed down shearing the pins which release the spikes into the tires causing deflation. All systems are measured from the first spike to the last, i.e. usable length. Included with every UMS system is a winding reel with 45 ft.of 150 lb. test nylon cord, 50 extra spikes with shear pins, a DVD, and a 5-year,100% warranty for any components, including spikes.
