Heavy Duty All Steel Fridge Stand Mobile Base with 4 Locking Wheels and 8 Sturdy Feet 16.9"-26" Adjustable Furniture Dolly for Washer, Refrigerator and Dryer（White）

I have a beastly heavy punching bag I'd like to be able to move around the house. This seems reasonable for the task.The rolling base has double heavy duty casters for a total of 8 wheels. Assembly is easy, just combine the two "U" shapes, otherwise you'll come to the final rod and not be able to insert it. You get some spare parts.First thing that makes this different than a furniture dolly is the legs/stands that have an adjustable foot that raises enough to make sure the thing can roll around. When in place, you can lock the wheels and lower the feet to stabilize the load (which is meant to be a washing machine or other large appliance).These feet make the cart unable to roll over carpet or any other obstructions, since it's so low to the ground and drags.The parts feel heavy duty enough and the side rods have measuring marks so you can adjust the size to fit various needs. The yellow squares have double stick material to hold the rubber pads on the load area.Moving a heavy load is a bit slow, but very easy to control. The wheel locks are a bit hard to get to depending on the angles and space you're working in, but lock things down nicely.

Works great for moving heavy items , was super easy to use
