RAM stands for Round-A-Mount and got its start in 1995. Most of the product line is based on a patented design revolving around a rubber ball and socket system. Far and away the most innovative product line of its kind, RAM continues to evolve into one of the most sought after accessories for electronics. RAM products have quickly become an essential mounting component for a wide variety of applications including rugged vehicle, industrial, military and defense, material handling as well as any application requiring a robust mounting solution. Incorporating a non-slip feature as well as shock and vibration dampening, our often imitated but never duplicated mounting solutions are truly one of a kind and enhance every application they are used in. Unwilling to compromise durability and versatility, many RAM products are available to support devices from less than a pound up to 185 pounds. Utilizing the finest assembly hardware, durable composites, steel, stainless steel, rubber, and aluminum, our mounting bases and complete kits are manufactured to perform above expectations and remain cost effective.
For over a decade RAM Mounting Systems has been synonymous with quality and performance. For your next mounting application, choose wisely. Choose RAM.
