Heavy Duty Polyurethane Caster Wheels For Shop Carts
✔️ Four Pack Casters 800 Pound Rating 5 To 8 Inch Polyurethane Wheel Sets

✅ Total lock brake locks wheel rotation and swivel for rock solid stationing
✅ Polyurethane skin bonded to heavy cast iron core resists chips and impacts
✅ 6-1/2 overall height clears obstacles while sitting low enough for tight spaces
✅ Top plate measures 3-15/16 by 4-1/2 to handle standard bolt spacing setups
✅ Pick either two rigid plus two locked units or go fully locked based on your gear layout

💡 Why pick polyurethane caster wheels over basic plastic tires for warehouse trucks?
Polyurethane grips concrete hard without flattening out under heavy stacks.
- Cast iron hubs swallow massive point loads without warping or cracking
- Dense rubbery tread drinks up floor vibration so loaded bins stay level
- Handy lock brakes kill movement dead yet pop free instantly when needed
- Smooth swivel action cuts push effort way down for tired operators
