Typically, roof racks purchased from Rackattack.com do come with detailed instructions for installation. These instructions are designed to guide customers through the setup process step by step, ensuring that the roof rack is installed securely and correctly. However, the specifics can vary depending on the manufacturer and model of the roof rack. It is important to check the product description on the Rackattack.com webpage for any specific details about the included instructions for the particular roof rack you are interested in. If for any reason the instructions are missing or you require further assistance, often additional resources, such as video tutorials or FAQs, may be available on the website. This can offer further guidance on proper installation and usage.
