This is a dolly used for SUP. The base has been reinforced to prevent wobbling. The weight capacity is up to about 15 kg, so it can be used for SUPs, longboards, etc., but not for kayaks. As a bonus, I'll include the 367 SUP SLING (with a storage waist pouch) in the photos. This is unused, but it has been taken out of the bag. A CAD-made stand-up paddleboard cart with an aluminum handle and large-diameter rubber tires. - Brand: CAD - Handle Material: Aluminum - Tire Type: Rubber - Handle Grip: Rubber grip - Tire Size: Large diameter Thank you for looking.
