These were the only viable 4" casters… These were the only viable 4" casters with 2" tread width (important for use on grass). High quality build, even come with greasing adapters.

Look for USA model casters! The casters I bought are *not* made in China! I avoid supporting communism whenever I can. Watch what you purchase, because not all of their products are made in the USA. The casters I bought (for a few dollars more than the communist casters) are very high quality and work flawlessly.

Good fit the first time Good fit. I found the 3-D model helpful in determining which casters would be best - I was able to open it in blender 2.8, and get the measurements to compare with existing equipment that I planned on retro-fitting without removing them from existing equipment. Good job on Faultless Caster to provide 3-D models of their products for this propose - even though I am certain they were intended to be used for designers. I love using these kinds of resources "off-book".

Confusing fulfillment My only complaint was that I called the 800 number on the site to ask questions about the product and talked to somebody at a distributor who was not the distributor who ended up fulfilling the order, so when I called back to track the order, it was a bit of a ordeal to figure out where it was, etc. The person at the original distributor was extremely helpful in tracking down where my order actually was, but it was just a bit confusing. In the end, the product was just what I needed and worked great!

I ordered 4 of the Shepherd Ball… I ordered 4 of the Shepherd Ball Casters in satin chrome. These were for an antique dresser I refinished. They are beautiful! The finish is deep and lustrous. I was very impressed. They function well too. Very smooth rolling. I only got an order confirmation when I placed the order, but never a shipping confirmation. So I was pleasantly surprised when they showed up only 4 days later. I would recommend Faultless Caster, especially for these particular casters.
