S4 L.L.C. Only deals in equipment that Keith has had long term experience in using. This is why the product line is limited. We use and carry, or have used and carried, on a daily basis, what we sell now.  

The company continues to do point of sale in West Milford, Morristown, and Florham Park, NJ. We are considering whether or not a virtual storefront meets our needs, please stand by.

Meanwhile, please check out examples of our new line of safety, security, and survival equipment on the pages at left.
