The 301 raised pavement marker (RPM) is the road stud most prevalent on British roads and motorways - the undisputed 'Heavy Weight' champion of the road marker world, weighing in at a whopping 4kg. Over two million of them are currently in operation throughout Britain. The 301 is a combination of a virtually indestructible cast iron base, within which, a 290 3M thermoplastic stud is simply inserted. The iron 'housing' completely protects the inserted 290 and it is a relatively simple operation to replace the insert, as and when necessary, after about 5-10 years of heavy usage. The 301 represents incredible value for money and is the ideal candidate for projects where heavy duty road studs are called for. The 290 3M thermoplastic inserts are used extensively in hot tropical climates, such as Florida, and are one of the most commonly used RPM's around the world.
