Review on 📦 SY America 4&#34 Material Handling Products: Enhancing Efficiency and Safety by William Rothstein

I've been using them for about a month on a custom DJ booth a friend built for me and they glide very smoothly. They didn't need any lubrication at all and ran smoothly for over 10 gigs with no rubbing. All in all a great purchase and I recommend the quality for the price. I replaced some plain rollers that I originally bought from Home Depot with these and they changed everything.
