Extension rods are long, slender tools used to extend the reach of various devices, such as paint rollers or camera tripods. They allow users to access hard-to-reach areas without the need for ladders or scaffolding, making tasks safer and more efficient. These rods are typically made from lightweight materials like aluminum or fiberglass, ensuring they are easy to handle. Many extension rods feature adjustable lengths, allowing for customization based on the specific job requirements. They are commonly used in construction, photography, and home improvement projects.
