All of our streamlined Harp Caddies are aluminum welded to ensure long lasting durability. Because of its convenient size, it easily fits in any vehicle. We use Colson Hi-performa wheels and a rubber covered base which provides a non-slip surface. Two industrial strength nylon straps with side-release buckles ensure security during transport. Red oak handles make a smooth bridge between the aluminum and the hand - giving a comfortable grip. The shearling wool cover on the curvature of the handle gives support and protection to the harp body. All models come with a 30-day, money back guarantee and full one-year warranty on parts and labor. With all these features, the Harp Caddy can take your harp practically anywhere (Mt. Everest excluded!).
