AR150 Desk and Cabinet Corner Mover Dolly, 1320 Lb Capacity/4 Pieces, 10.5" Length x 10.5 Width x 3.35" Height (Case of 4)

I bought these to help me move heavy items (furniture; a massive Seaton Submersive subwoofer, etc.) as I navigate through the conclusion of my home construction project. I primarily but them for the sub because it is ultimately going under the stairs . . . where the vertical clearance is limited. These do not raise the unit very much, making it easy for me to leave the sub placed, but still allowing for my contractors to slide it out as needed - no, I will not be leaving the sub on these permanently (not that I can tell that there is a difference in the audio . . . but I'm sure it should be directly coupled to the floor).These work so well! I could not be happier, completely worth the price. They roll very easily, direction changes are a piece of cake. They are VERY heavy duty. I own several sets of those small 'star' shaped dollies. The work OK, but I find that things slide off of them easily and that the wheels get stuck on bumps, grout lines on tile, and other things. These roll right over those.That said, they are corner units. If you bump into something that you need to roll over (which is sometimes unavoidable), you will need to take care not let one of the corners slide too much.I imagine that this is less of an issue with heavier items.One upgrade would be to put rubber or felt pads in the corner of the units (where the item you are moving rests). I was a little worried about scuffing the wood of the item I moved (this has not happened). I'm going to add some extra foam door seal that I have laying around the house to address this.

Concept great, but could be far better if offered capability of keeping them under the item being moved; the rubber pads don't help. Significant improvement would be to augment product by adding vertical posts where each caster is located. User could then use an adjustable strap to cinch all four corners so none could slip off. This would permit a single person to move item - without another person to keep all 4 units under the item being moved. Posts could be unscrewed if get in the way of the item being moved. I achieved the same effect by fastening c-clips to each unit and then fastened an adjustable strap to keep the 4 units under the item being moved. Did the job, but would have preferred to have posts integral to the unit as bought. Manufacturer could offer as upgrade package - with a durable adjustable strap included.

These caster devices perform smoothly and are quite easy to load with furniture and cabinets. The floors in my house are slightly uneven. This resulted in one or more of the four caster units periodically slipping out from under the load which remained aloft on the three remaining caster units. As I became more experienced with using them I paid more attention to confirming that all four corners were still supported by one of the red caster units. The system works quite well. I will continue to use them to move intermediate and heavy loads over smooth surfaces.

Item was shipped quickly. Used this to move medical lab station which weighed about 800lbs. I used these by myself on the first unit and was able to put them in place by using a Johnson bar. Once in place I was able to move the unit by myself with no problem. Much better than I expected after reading some of the negative reviews. May buy another set for my company so that we can have them on hand when needed.

I have a large gun safe that needs to be moved several times as I remodel my home home office. Each move would cost $500 if done by "professionals". This Dolly Set coupled with the https://www.amazon.com/Vestil-PLB-5-Prylever-Length-Capacity/dp/B0052PP3NC/ref=cm_rdp_product means that I can move an 1100 lb safe as often as needed by myself. The low deck means that it is very easy to get each corner in place quickly and securely. Excellent heavy duty construction. Quality all around. I'm already eyeing other heavy items that could be "moved" just for the fun of it.

I have a 6' x 8' storage shed on the side of my home. When the shed was put in the installers covered the plumbing clean out so I was unable to use a rooter to unclog the plumbing drainage.So now I put these corner movers underneath the shed and I can easily push the shed to a new location . So these corner movers worked out great for this project.They are sturdy enough to hold up the wieght of the wooden shed.

Product does not stay on while moving. One corner seems to “walk off” as soon as you rotate the safe. I gave it 3 stars because it’s a design flaw. If it was deeper or correctable with a tie down around all 4 corners then I would have given 5 stars.

moved a metal lathe with these guys. i think it weighed about 1200 lbs. it got a little wonkey when one of them slid out. but when they were are all load bearing it was fine.
