Ball Base Information
"RAM" Prefix Code
To provide lightweight strength and corrosion resistance, RAM is made of marine grade Aluminium with a black powder coated finish, stainless steel hardware and 'rubber balls' - 'RAM' products are stiffer and stronger than their 'RAP' variants and typically used in more rugged applications.
"RAP" Prefix Code
Many of our 'RAM' products are available in a 'RAP' - composite variant. Our composite 'RAP' products are generally designed for lighter duty applications where keeping the weight of the mount low is a priority.
