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.

Customer service is on their game! Within roughly an hour of placing my order (casters without brakes), I was contacted by a Faultless Caster employee explaining that the item I ordered was out of stock and wouldn't be restocked for a few more weeks. They offered to send me the same casters I had ordered but with brakes at no extra charge. I accepted their offer and the casters were at my house in no time at all. Easy to work with and the casters are just as pictured.

Customer Service is OUTSTANDING!!!! Customer Service is OUTSTANDING!!!! I placed an order, item was on back order, they called me to let me know about the delay......they called me!!!!!! The representative wanted to make sure this delay wouldn't effect my project deadline. That is awesome!!! Once I received my order, I realized I needed something a little different. I called and they walked me through their products and helped me get what I needed. Everyone was very very helpful. I would give you 10 stars!!!

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".

Easy to navigate, comprehensive website Easy to navigate website and detailed descriptions of casters made matching them to our old ones a breeze. What an excellent source for replacements!
