Universal Modular MultiMount - Composite Black, Composite Red or UM3-QRM-CMSS mount is an engineered composite mount designed for lightweight, strength, corrosion resistant environments, yet performs as well as the Billet mount, but at a lower price point. Perfect for lighter duty appliances, including fire extinguishers attached to chase trucks, jeeps, lawn equipment vehicles, ocean going vessels, and the millions of passenger cars that carry fire extinguishers. UM3-QRM-BSS (Billet) aluminum mount is the most advanced, designed for all weather, high load and stress conditions for off-road or marine environments. It has no length limits for cylinder mounting with the Patent Pending 'drop and slide' design. All mounts can be easily attached anywhere with either clamps or bolts (not included). They are being used for air tanks, search lights, shovels, drive shafts, fuel cans and more. UM3 comes in two parts. The Base is attached to a wall using screws or bolts, or to a tube using metal straps. The Mount is secured to the base with a stainless-steel pull pin and lanyard.
