Are you finding it difficult to launch your boat off of your trailer? With good quality rollers on your trailer, launching and retrieving is a breeze. There are three types of rollers that you can choose from. Black rollers are the conventional roller type, made from soft, hard-wearing rubber. Red rollers are made from soft, hard wearing polyurethane which is less abrasive and reduces hull marking, making them ideal for fibreglass boats. The blue rollers are made from hard polypropylene. They are less abrasive and reduce hull marking, however due to their hard construction they are more suited to aluminium boats. Ensure you always install the correct size and type of roller to suit your boat. If your rollers are not spinning with ease, check your roller spindles and brackets to see if they are in good condition and replace them when required.
