The Original Royal Wire Rolling Dolly makes lugging saddles to and from horse trailers to tack stalls a cinch. This is one of Royal Wire's best selling products. The Rolling Dolly is expertly designed to be a versatile component of your Royal Wire equine organizational system. The Rolling Dolly is a two-tiered, four wheeled system. The dolly comes with a welded-on 3-hook bridle rack and a roomy 20" x 13" basket on the bottom. By itself, it's great for moving tack trunks and heavy bales of hay. Customize your Rolling Dolly by choosing any two of the following product options: Saddle Racks, 18"x 13" Basket, Speed Rail, Flat Shelf or Saddle Pad Holder. Please note that all of the above options are sold separately and are interchangeable with our Main Frame System. To show off the Rolling Dolly's versatility even more, it collapses for convenient transportation and storage. A wide base with high quality, large hard rubber tires provides stability, while the front swivel casters make taking tight corners easy. Manufactured out of 1" square tubing and 3/8" diameter basic steel and is zinc plated to guard against rust and corrosion. Dimensions 52"W x 31"D x 19"W. Simple assembly required.
