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 various types of rollers that you can choose from and it's important to choose good, solid rollers to support your boat on the trailer. This grey ribbed wobble roller is constructed from soft, yet hard wearing polyurethane, which is less abrasive and reduces hull marking, making it ideal for fibreglass boats. Ensure you choose the correct size of wobble roller to suit your boat and install the roller in the right spot for centering. 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.
