Review on 🔩 StarTech.com Heavy Duty Caster Kit for Open Frame Rack - TAA Compliant with Easy Installation Hardware - Set of 4 (4POSTCASTER) by Shane Schobinger

I bought these to install in my StarTech.com 36U 4POSTRACK36 Adjustable 4-Station Open Frame Server Rack (Black) and I couldn't be happier! They are extremely durable. I considered looking elsewhere for cheaper ones but was put off by their pound rating. The server rack they support weighs around 100 pounds alone. In addition, it has 7 2U UPS/batteries (probably just £350), 3 4U servers (probably just £100) and a bunch of networking equipment (probably just another £50). So they can support about 600 pounds sitting on a semi-soft Berber rug and I can slide my rack out of the wall pretty easily. I'm very impressed with how well they move this weight across the carpet and generally how well they handle that much weight (I know it's more than what the manufacturer says on the roller specs). If you are interested in the specs, the mounting holes are approximately 1.75 inches. " apart on the narrow side and 2.25 " on the long side. Two casters have locking levers, two don't. All castors are pivotable. They sit about 3 inches tall.
