This is a great product.

At time of my purchase of these, the hole pattern in product pics was shown to be 1.7X2.5in on centers of slots. Slot dimensions shown as 0.3x0.4in. Actual hole pattern is 1.76X2.88in. Actual slot size is .33X.47in. This means that the 2.5in shown in pics is actually the ~minimum dimension between slots. So if you designed mating parts to that 2.5in center shown in pics, installing the fasteners is impossible. To the person that measured the parts for the product pics: Good job! You almost got it! Keep trying, one day youll finally read that tape measure correctly, and then theyll be no limit to what you cant do! Otherwise, these seem to be as advertised.

Heavy duty and good looking. Installed on a 4 ft long storage bench that took 2 ppl to move. If I didnt have to make a trip to Home Depot to purchase washers my rating would have been a solid 5 star.

I built a platform for my stand up freezer and added these wheels to help roll it around. They are built very well and could hold a lot more weight than what I am using them for. They have a nice look and finish too.

Work well on my 4 x 8 foot assembly table

With in 1 day the brings came out of their mounted area.

I got this set to put on the bottom of a rolling stool that I built and they work great! They were easy to install and with my substantial frame on the stool, they roll and pivot very easily. I may get more at some point in the future for various projects.

One of wheels had brake clamped when delivered, it caused a large dent (flat spot) in rubber where brake contacted wheel. I dont roll it around enought to worry about flat spot on wheel but It conserns me that all wheels will develop flat spots from sitting.

I built a work table for my wife for her stained glass hobby. A pull out tray under the top stores about 200 pounds of glass and a compartment on the side stores all of her layout boards. The table rolls super smooth. For being made in China, these casters seem to be well built and have bearings instead of bushings. They work well enough that I ordered another set for a flip top table I am going to build for my thickness planer and miter saw.

Very nice, even came with bolts to mount.
