Set of 3 Plow Dollies. Each Dolly holds 350#, and has locking wheels to prevent rolling. We use these in our shop every day. Molded polymer top has groove for cutting edge to sit in. Approx. 6.5" x 6.5", 4.75" tall overall. Orange powdercoat finish on steel base. We love these dollies! We have tried others, but these have worked the best. Customers always ask about them when they see us use them to mount their plows. Here they are. Remove the plastic top from one to use with an EZ PLus and Crankstand (see pic).
